Category Recognition in the Monkey Orbitofrontal Cortex
The orbitofrontal cortex (OBF) is known to play important roles in evaluation of reward value based on integration of multimodal sensory inputs. In this study, we investigated the complex cognitive functions in the OBF neurons from rhesus monkeys (Macaca mulatta). Glass-coated Elgiloy electrodes and tungsten fiber multi-barreled glass microelectrodes have been used for extracellular recording during behaving the visual discrimination task. As a result, Neurons showed a wide variety of selectivity for these complex images. OBF neurons are involved in various levels of categorization and integrate various endogenous humoral signals and specific exogenous sensory cues.
