| Research Abstract |
The purpose of this study is to characterize the integrative properties of the cardiovascular/pulmonary systems that are distributed, rather than those which are properties of individual cells. We will specifically focus on those properties which relate to interactions among the component neurons. The technology best suited for carrying out these studies is multiple-site optical recording using voltage-sensitive dyes, which can provide high resolution(temporal and spatial)views of neuronal activity throughout cardiovascular/pulmonary systems. The proposed experiments take advantage of the special expertise, facilities, and different preparations used in the laboratories of our group in order to identity basic principles by which networks integrate neuronal information. "Distributed processing" has been used to label several phenomena. First, it can refer to instances where large numbers of neurons in one or several regions of cardiovascular/pulmonary systems are involved in generating each behavior. Second, it may refer to situations where individual neurons are multifunctional : each cell is involved in the discrimination of more than one sensory input or the generation of more than one behavioral output. Third, distributed processing refers to situations where synaptic strength of the connections between neurons are low and activity in many excitory and inhibitory inputs are evaluated in determining the output of each individual neuron. The experiments in this study examined all three aspects of the distributed processing.
