Long-lasting, context-dependent modification of stepping in the cat after repeated stumbling-corrective responses.

abstract：:Unitary discharge patterns (peristimulus time histograms or PSTH) and synaptic events were studies with intracellular recording techniques in 164 cat cochlear nucleus cells to steady-frequency tone bursts 250 ms in duration. There were four response types defined on the basis of the shape of the discharge patterns to ...
