Excitatory interactions between phrenic motoneurons: intracellular study in the cat.

abstract：:In order to relate single cell performance to behavioral discrimination one needs measurements of the response variance of the units. We recorded from 183 single units of area V1 of monkeys performing an orientation discrimination task. The response variance was found to increase with increasing response strength. Thi...
