Research Abstract |
To investigate neuronal mechanism for interval timing, especially for temporal discrimination of sensory stimuli with different modality, we recorded neuronal activity from prefrontal cortex of animals performing a temporal discrimination task using visual and auditory stimuli. Many prefrontal neurons selectively responded to visual and auditory stimuli during stimulus presentation periods while a group of neurons represented relative duration for visual and auditory stimuli in a discrimination decision phase. These results suggest temporal information of visual and auditory stimuli is processed partially in different neuronal networks in prefrontal cortex.
