Optical reporters of synaptic activity in neural circuits.

Abstract:

:One of the most basic computational elements within a circuit is the synapse across which signals are transferred. Here we summarize some experimental strategies that allow the synaptic basis of circuit function to be studied through imaging. The two most promising approaches available currently are pHluorin-based reporters of synaptic vesicle fusion and genetically encoded calcium indicators localized to presynaptic terminals. Other potential approaches include the optical sensing of local voltage changes or of neurotransmitter substances, but the spatial and temporal sensitivity of the current reporters would need to be improved.

  • Segmental heterogeneity of rat colonic electrogenic secretion in response to the bacterial enterotoxin Escherichia coli STa in vitro.

    abstract::The effects of the bacterial toxin Escherichia coli STa on electrogenic secretion in proximal, mid and distal rat colon were examined in vitro using the short-circuit current (Isc) as an index of secretion. All areas showed toxin-elevated Isc which was reduced by bumetanide. The proximal colon was the most sensitive (...
