Neuronal activity in the monkey prefrontal cortex during a duration discrimination task with visual and auditory cues

Abstract To investigate neuronal processing involved in the integration of auditory and visual signals for time perception, we examined neuronal activity in prefrontal cortex (PFC) of macaque monkeys during a duration discrimination task with auditory and visual cues. In the task, two cues were cons...
