ABSTRACT
This study aims to investigate whether the position of the eyes affects the neuronal activity in auditory cortex in a condition in which not the active control of eye position but the execution of hand movements was required relative to stimuli. Two monkeys were trained to perform audio-visual tasks in which they had to use their hand to respond to both the visual and the auditory stimuli to earn a reward. We recorded the spiking activity and the local field potentials from the core fields of auditory cortex, along with the eye position of the monkeys while they performed the tasks. We found that both the spiking activity and the local field potentials did not significantly vary with the eye position. This was the case both during the presentation of sounds and during other periods of the tasks. Our results indicate that eye position did not affect the neuronal activity in auditory cortex during the audio-visual tasks. Our results, together with the previous finding that eye position affects the neuronal activity in auditory cortex during eye fixation tasks, suggest that the presence of eye position effects in auditory cortex depends on the specific behavior a subject has to exhibit to obtain a reward.
