Developmental changes in electrophysiological properties and synaptic transmission in rat intracardiac ganglion neurons.

abstract：:1. The homeostatic model of delta sleep has provided a useful framework for basic sleep research. This model is based on the relation of delta EEG to the duration of prior waking in man, a relation highlighted by the marked increase (rebound) in the delta EEG of nonrapid eye movement (NREM) sleep that follows total sl...

We describe a four-layered neural network (Fig. 1), based on the input organization of a collision signaling neuron in the visual system of the locust, the lobula giant movement detector (LGMD).
