Levels of Spontaneous Activity and Spike Responses of Cortical Neurons to Local Administration of Excitatory Amino Acids to Their Dendrites and Bodies
- 26 Downloads
Studies of cortical cortex slices showed that spontaneous neuron activity depended on the conditions of transmission of excitation from dendrites to the body. Studies using a measure of the efficiency of dendrosomatic conduction showed that cortical neurons constituted a significantly heterogeneous population. Spike reactions to direct excitation of cell bodies were relatively stable in neurons with different levels of spontaneous activity.
