Deep temporal lobe projections to the nucleus of the diagonal band of Broca

Summary Electrophysiological studies with acutely prepared cats found that stimulation of deep temporal lobe structures (e.g., amygdala, prepyriform cortex) evoked responses in the nucleus of the diagonal band of Broca. An analysis of field, extra- and intracellular unitary responses points to the existence of a monosynaptic excitatory connection.This work was supported by NSF Grant No. GB 35532 and NIH Grants Nos.
