I hope to develop, along
with collaboration of faculty in the College of Education and Biology,
modules which will be cross-disciplinary. I plan to develop modules on
fecundity curves of Drosophila with various numbers of females
and mix in number of males, one male and various numbers of females and
vary environmental factors such as temperature and types of food. With
the data collected I will develop a means for teachers and students to
use mathematical models to explain the collected observations. The mathematical
models can be used to predict the impact of environmental disturbances
which could influence fecundity (egg laying). Then experiments can be
performed to test if the predictions in the mathematical model hold or
if adjustments in the model need to be performed. sampotter@me.com

My project is to have the
high school students act like scientists as they explore health problems
and present findings from their classroom projects at the annual Healthy

This will allow students to take their research findings and information
directly to the locals, instead of trying to entice the locals to attend
a Health Fair.) The students, teachers, and project staff and scientists
will share their knowledge and leadership to enhance and support health
in communities by presenting annually at a Healthy Flea showcase held
in partnership with local health departments and/or health entities. The
local health depts. and nursing students in nursing programs can use these
events for screening the public for various health related issues and
help the high school students and their teachers answer questions from
the public. I will also be working with Ms. Feld (UK nursing school) and
her public health class. I hope to coordinate the county health dept activities
with the school teachers and their projects as well as the nursing school
students for the activity of the healthy flea presentations. Scientifically
I will be working with the high school students and their teachers to
insure the science and resources used are legitimate and have a sound
footing before public presentation. This will involve learning about various
topics and reviewing the student’s research and presentations. Some
of these activities I hope to cover via Skype along with Dr. Cooper and
faculty within the College of Ed at UK. daniellemiddleton222@gmail.com

The effects of
an altered serotoninergic system on behavior and development in Drosophila
melanogaster
ABSTARCT
Drosophila
is a simple model system that provides an advantage over vertebrates to
modify genetically and for electrophysiological studies on identifiable
cells. In this organism the sensory-CNS-motor circuit is modulated by
5HT, OA, DA, which gives one insight that these neuromodulators are playing
a role in central neuronal circuits. The role of 5HT in the behavior and
development of Drosophila melanogaster larvae is being studied. p-CPA
(para-chlorophenylalanine) blocks the synthesis of 5HT by blocking the
enzyme tryptophan hydroxylase. The developmental and behavior differences
in a 3rd instar larvae after feeding this drug for a chronic and acute
period is to be observed. Alteration in the central nervous system biochemically
and anatomically will also be investigated.
AIM
Address the role 5HT plays in the development of Drosophila and
changes in central nervous system physiological response due to pharmacological
manipulations (by feeding p-CPA) during the development.
My
project revolved around chemical synaptic transmission. Within the presynaptic
nerve terminal, transmitter is packaged within spheres called vesicles.
When these vesicles fuse with the presynaptic membrane they release transmitter.
The fusion of the vesicles with the nerve terminal is very dependent of
the amount of calcium within in the terminal during stimulation. The more
calcium that comes in the greater probability of a vesicle fusing with
the membrane. Likewise the longer free calcium stays in the nerve terminal
after a stimulation the more prolonged time for vesicular events to occur.
I am a MS student
in Biology. My focus is in understanding properties of synaptic transmission
using fruit flies and crayfish as model preparations. I am an active officer
in the Korean Military (Seoul, South Korea).
I
am working on behavioral projects with crayfish in relatation to social
interactions and sensory perception. I am a high school student at Dunbar
High School.
My goals are to
determine the mechanisms of action by which 3,4-Methylenedioxymethamphetamine
(MDMA, "Ecstasy") can enhance synaptic transmission at 5-HT
sensitive synapses in the Drosophila brain. Since Sameera, in our
lab, has developed an in-situ preparation to induce motor unit activity
by stimulating a sensory-CNS circuit, using the 3rd instar larvae of Drosophila
melanogaster, I will use this procedure to address the role that MDMA
has in altering the activity and determine if the actions are mediated
by 5-HT receptors. The powerful genetic manipulation in Drosophila
opens many avenues for further investigations into the circuitry and cellular
aspects of pattern generation and developmental issues of circuitry formation
and maintenance in the model organism.

On repetitive
stimulation, certain motor neuron terminals (i.e. the crayfish tonic opener
motor neuron) do not rapidly depress over a period of hours for short
trains of stimulation at 40Hz but can continually demonstrate STF. When
a short train of pulses at a given frequency (20 pulses at 40 Hz) is applied,
the excitatory postsynaptic potentials (EPSPs) may reach a plateau in
their amplitude during the pulse train. This higher [Ca2+]i can activate
silent synapses and result in new vesicle docking sites to be active.
I hope to monitor if these new sites can be detected by differences quantal
recordings. It is assumed at present that synapses might have a "quantal
signature" that can be used for quantifying their activity.

The quality and
quantity of food is very important to development of animals. Not only
is this necessary for life but for the reproduction of the species for
fertility. More subtle effects of diet can also be seen in relation to
learning and memory. Such general phenomena not only apply to humans but
to all animals. Thus studying such topics in model organisms like fruit
flies may allow one to gain a better understanding of the consequences
in humans related to these topics. The basic features of growth and development
of Drosophila have been studied in the laboratory for many years. The
animals used for these experiments are small organisms, easy to rear and
to count, with a short life cycle. Females tend to lay eggs for only about
5 days and then taper off. Many variables affect the population dynamics
of growth. This investigation will deal with variation in density of females,
composition of food sources, and in environmental factors such a temperature
and light. Other factors can also be considered and pursued. However I
plan to focus on how the quality of food affects development and fecundity.
In addition, I plan to examine learning in larvae as well as adults based
quality of food.
I
obtained a BS in Biology from EKU in Richmond, KY (Go Colonels!) and decided
to go to graduate school at the University of Kentucky in Neuroscience.
I investigated the structure pre-synaptic nerve terminals and its relation
to neurotransmitter release. I did so utilizing the macropatch recording
technique and transmission electron microscopy (TEM). To know more please
download my Ph.D. project: {PDF}
The crayfish tonic opener muscle offers the advantage of being able to
record quantal events at specific visually identified release sites, thus
allowing measurement of the physiological parameters of vesicle release
which can be used to directly correlate synaptic structure.
These
experiments take advantage of a vital dye (4-Di-2-Asp), which highlights
nerve terminals allowing visualization of individual low output varicosities
(sites of neurotransmitter release). Once one is located it may be "bookmarked"
by the use of polystyrene beads, which are both fluorescent and election
dense. Electrophysiology may then be performed and the site marked for
structural analysis. By labeling the nerve terminal recorded, it is possible
to serially thin section the exact area and visualize it by TEM. These
electron micrographs may then be reconstructed into a three-dimensional
representation of the area recorded and the ultrastructure may then be
compared to different aspects of physiology for a direct structure/function
assessment. Release sites on synapses known as active zones may then be
identified and their number and spacing revealed.
.................My 1st TEM !!
I
am from southern India and joined the lab in January 2003. My projects
involved pharmacological assessment of the central and peripheral receptors
to various neuromodulators in Drosophila (fruit flies).
The
ability to combine a genetically favorable system and pharmacological
studies is opening new horizons in regulation of development, regeneration
and repair of central neural circuits. In addition, neuromodulators provide
a rapid way in which animals can tune up or down activity within a neural
circuit and may be responsible for rapid changes in behavior, as recently
examined for aggressive behavior in Drosophila. I am assessing
three common neuromodulators of interest in arthropod neurobiology: serotonin
(5-HT), octopamine (OA), and dopamine (DA). There is a precedence of 5-HT,
DA, and OA to have central effects in the Drosophila brain.

to actions of nicotine in Drosophila melanogaster.
If I
can demonstrate in either larvae or in adults that known antagonist to
nicotine receptors can block addictive nicotine behavior it could be used
to aid vertebrate studies on the subject. The results might be useful
for human studies as well as basic studies of understanding the receptor
subtypes within a model organism, the fruit fly.

I
am currently a junior Biology major looking forward to knowing more about
neurobiology. I plan to start working on projects involved on synaptic
homeostasis in crayfish muscles which compliments other studies on going
in the lab with the Drosophila NMJs.
The
advantage of studying synaptic transmission at the crayfish neuromuscular
junction is that the sites of synaptic contact can be studied directly.
The neuromuscular preparations in the crayfish offer many advantages as
compared to vertebrates neuromuscular junctions (NMJs), since one to only
a few excitatory motor neurons innervate a muscle, and the neurons are
identifiable from preparation to preparation. In addition, the excitatory
neurotransmitter is glutamate and the excitatory postsynaptic potentials
(EPSP) are graded; thus, the biophysical properties of graded events are
analogous to the dendrites of neurons within the CNS of vertebrates, but
the quantal currents can be monitored at the postsynaptic sites in the
crayfish NMJ.

I am following
up on research started by my husband Joe (see below under past students).
Learning is a complex task for animals since it involves various neural
circuits and environmental context during a learning period. In addition
researchers have broken down learning into various forms. A simple form
of learning is associative learning. A well known example is Pavlov with
dogs. Dogs were trained to associate a bell or a light with food. Since
a intact functional nervous system is essential for learning, it is not
surprising that the behavioral state of an animal is important in the
ability to learn. Likewise if the neural circuits are modulated by substances
either that are endogenous to the animal or introduced exogenously learning
can be impaired or even enhanced . Since it has already been demonstrated
that 5-HT (serotonin) can alter electrical activity of the larval brain
then any alteration in its levels might also effect associative learning.
Amazingly enough even insects, such as adults and larval Drosophila, demonstrate
associative learning.

I am examining
the CNS activity to known 5-HT receptor agonists used in vertebrates.
Known antagonists will also be used to see which ones can block the effects
to exposure of 5-HT. These same agonists & antagonists will also be
used on the larval heart to test their effects. These studies will aid
in pharmacologically identifying the 5-HT receptor subtypes and their
localization.

Maurice-Pierre is now a 2nd yr Medical Student (MD program) at UK, but
we are still working on some projects.
I
am a displaced French Canadian and somehow ended up at UK for my undergraduate
studies. Next year I will be attending UK's medical school. Over the last
year I have been working on how novelty stress and reproductive state
alters responsiveness to sensory stimuli and 5-HT neuromodulation
Stress
in animals induced by environmental stimuli may arise in several forms.
One such stress is novelty induced stress by exposing animals to stressors
that they are not normally provided in their natural environment. Environmental
stressors can also be induced as stimuli but of intense levels to what
are found within their natural setting such as light or noise. In examining
how animals react to additional stimuli when stressed allows one an insight
into the physiological status of the animal. It is well known that pharmacological
agents show varied responses in animals which in some cases is due to
the behavioral status such as in a hyper excited or relaxed state.

I
have been in the Cooper lab since the beginning of time. I am originally
from Kentucky and have found UK a convenient place to pursue an undergraduate
education. With a Beckman fellowship I have been able to live off a good
stipend for the last year in order to spend time learning about research.
I am looking forward to going on to medical school next year and I plan
to continue with research throughout medical school training and in subsequent
years.
My
project revolved around chemical synaptic transmission. Within the presynaptic
nerve terminal, transmitter is packaged within spheres called vesicles.
When these vesicles fuse with the presynaptic membrane they release transmitter.
The fusion of the vesicles with the nerve terminal is very dependent of
the amount of calcium within in the terminal during stimulation. The more
calcium that comes in the greater probability of a vesicle fusing with
the membrane. Likewise the longer free calcium stays in the nerve terminal
after a stimulation the more prolonged time for vesicular events to occur.
The
purpose of my studies is to determine if the release process maybe saturated
during the plateau phase in the presence of high frequency stimulation
when further increases in stimulation frequency failed to enhance transmission
significantly. To test this possibility, serotonin (5-HT) was used to
further enhance release during this maximized plateau phase. 5-HT is a
endogenous neuromodulator in the crustacean model that I am using to investigate
these principles. The use of 5-HT to promote synaptic efficacy, instead
of higher [Ca2+]o , prevented the resetting of the Na-Ca exchanger and
displacing ionic driving gradients which would have differential effects
on the potential recruiting of new release sites. A second series of experiments
examined the impact of off-setting the Na-Ca exchanger on the plateau
of the EPSP amplitudes during STF.

I am a senior biology
major at Centre College in Danville, KY working in Dr. Cooper's lab for
the month of January. My work is centered around synaptic transmission
and neuroelectrophysiology in crayfish. After graduation in May, I hope
to go on to graduate and medical schools. My biggest interest lie in neurodegenerative
disease and in examining the brain during the process of aging. I would
like to, one day, do both research and practice medicine.
Hyun
Sik Yang
I
am a premedical student at Seoul National University, Seoul, South Korea.
I am working in the laboratory from January to late February 2004 to learn
neurophysiology techniques related to measures of ephaptic communication
between neurons. The project consists of intracellular recordings from
motor neurons and investigating the influence of electrical activity of
one axon on a closely associated neighboring neuron enclosed in the same
glial sheath. Ephaptic effects occur since axons are confined by restricted
extracellular volume in the same space enclosed by a glial sheath. Large
extracellular voltage changes as a result of electrical activity in the
form of action potentials can result in ephaptic excitation in another
neuron or cell. This is the foundation of the spread of epileptic activity
and sensory pain due to muscle or motor nerve damage in humans.
Mark
Lancaster (PhD-2007 in Statistics)
My PhD research in the Statistics department has centered around writing
software and analysis of synaptic function by quantal analysis. Investigating
the function of individual synapses is essential to understanding the
mechanisms that influence the efficacy of chemical synaptic transmission.
The known simplicity of the synaptic structure at the crayfish neuromuscular
junction and its quantal nature of release allow an assessment of discrete
synapses within the motor nerve terminals. My goal is to investigate the
effect of the stimulation frequency on the number of active release sites
(n) and the probability of release (p) at those active sites. Because
methods based on direct counts often provide unstable joint estimates
of (n) and (p) and underestimates n, we base our analysis on mixture modeling.
In particular, the mixture modeling approach is used to estimate (n) and
(p) for stimulation frequencies of 1Hz, 2Hz, and 3Hz. Our results indicate
that as the stimulation frequency increases, new sites are recruited (thus
increasing n) and the probability of release (p) increases. The increase
in (n) and (p) are not as well reflected by estimates obtained by direct
counting procedures and binomial distributions. Funded by NSF grants IBN-9808631,
