to use crustacean preparations to investigate the properties involved in synaptic
recruitment in low -and high-output synapses in motor nerve terminals. With the
combination of ultrastructural and physiological analysis of specific synapses,
direct functional correlations are being made.

& Dr. Kert Viele (Dept. of Statistics, Univ. of KY.)
we are collaborating on a statistical problem with synaptic transmission in Drosophila
related to neuromodulation.
Dr. Seongjai Kim (Dept. of Mathematics,
Univ. of KY.)
We have continued projects that develop quantitative sterological
methods for reconstructing the dimensions and spatial distribution of synaptic
structures in the pre- and post-synaptic tissue from conventional transmission
electron microscopy. Dr. Kim has the computational abilities to provide programs
for the analysis of the biological problems that I address.

Investigating differential expression of GABA
transporters and aminergic synthesis in distinct arthropod species. This research
is multidisciplinary, and includes molecular, biochemical, electrophysiology,
behavioral and genetic approaches towards understanding the regulation of synaptic

Molecular & physiological investigation of synaptically significant
molecules involved in transmission at the NMJ.
Dr. James Winslow (Univ. of Toronto, Dept. of Biomed. Eng.,
We are continuing our collaborative project on Ca2+ domains at active
zones among neurons that display synapses with complex structures,
such as with active zones of different sizes and their relative
closeness to each other.

Examining the regulation of muscle isoforms in
specific types of crustacean muscles.

We are investigating the potential
role of an autonomic nervous system in crayfish. In addition, we are using physiological
measures of heart rate (HR) and ventilatory rate (VR) of crayfish following presentation
of a defined sensory stimuli. Since behavioral observations do not allow an internal
status to be assessed, it is suggested that HR and VR may serve as useful bioindices
in crustaceans to their internal drive or possibly an awareness level to environmental
