Cortical Neuron Activity in the Temporal Organization of Behavior
Neuropsychological studies in primates have implicated the prefrontal cortex and also (with regard to vision) the inferotemporal cortex in the integration of temporally separate items of sensory information. Single-unit studies support such evidence and point to the involvement of neurons in those neocortical regions in the mechanisms of temporal integration. Sustained elevations and diminutions of firing related to the retention of cues in delay tasks suggest participation of those neurons in the mnemonic process that makes that form of integration possible. Protracted and color-dependent changes of firing, after color cues to be provisionally retained by the animal in performance of a task, indicate that inferotemporal neurons are specifically involved in visual short-term memory.
