This study investigates the influence of microstimulation on face categorization through the analysis of face-selectivity neurons in the inferotemporal (IT) cortex of macaque monkeys. Utilizing electrical stimuli at 200 Hz for 50 ms, we explore correlations between neuronal selectivity and behavioral outcomes, focusing on the impact of the size of selective neuron clusters on stimulation results. Our findings contribute to understanding how microstimulation affects face processing and reward mechanisms, shedding light on neural pathways involved in visual categorization.
