The precise relationship between cortical activity in the sensory areas and perception remains elusive. The perception of a given sensory stimulus can vary depending on the state of ongoing neural activity. Previous electroencephalogram (EEG) studies in humans have demonstrated distinctions in the power and phase angle of alpha oscillations (8-12 Hz) in the occipital region just before the stimulus onset between successfully detected (hits) and undetected (miss) trials (Busch et al., 2009; Dugué et al., 2011). Additionally, electrical microstimulation of V4 has shown to enhance performance in a visual detection task (Kienitz et al., 2022). To delineate neural activity during perceptual hit and miss trials in greater detail, we analyzed the multi-unit activity (MUA) and local field potential (LFP) from chronically implanted 96-channel Utah arrays in visual cortical area V4 of two macaques. During each trial, a stimulus was presented, followed by microstimulation in V4 and a subsequent target flash. The monkeys reported target detection through saccadic responses. Our preliminary results indicate an increase in target evoked MUA during hit trials compared to miss trials. This increased target response for hit trials was present both in trials with and without electrical microstimulation. In contrast, any pre-target activity was much weaker and more variable. These findings suggest that a state dependent modulation of visual target representation in visual cortex.
