Research Abstract |
Elucidation of neocortical organization principles is crucial for understanding the function of the cerebral cortex. We quantitatively identified excitatory pyramidal and GABAergic nonpyramidal cell subtypes. We found that the neuron subtypes exhibited selective connectivity and that GABAergic cells discharged during the local and global rhythms. Thus, the local synaptic organization and firing activity in the neocortex are specified according to global inter-regional circuits and their oscillatory interaction.
