Oxidative downmodulation of the transient K-current IA by intracellular arachidonic acid in rat hippocampal neurons.

abstract：:The dorsal premotor area (PMd) of monkeys has been implicated in processes relating to movement preparation and movement selection. In the present study, we sought to determine whether PMd neurons that are activated during a delayed reaching task have directional responses that reflect either the target (i.e., the goa...
