Dopamine modulation of phasing of activity in a rhythmic motor network: contribution of synaptic and intrinsic modulatory actions.

abstract：:1. We studied the effect of zinc on the gamma-aminobutyric acid-C (GABAC) receptor in acutely isolated catfish cone horizontal cells using the whole cell patch-clamp technique. 2. GABA activates the GABAC receptor with a half-activation concentration (EC50) of 2.99 microM. The Hill coefficient is 1.32. Desensitization...
