| Research Abstract |
To investigate roles for pyramidal cells (RS) and interneurons (FS) in prefrontal cortex (PFC) underlying choice behavior, we recorded neural activity during task performance and analyzed how single (multiple) neurons code the upcoming choice.
RS and FS similarly contribute to the choice behavior. When cues were novel for rats, ensemble activity was similar as that when the cue was familiar. It suggests that prior experiences in the PFC bias the ensemble patterns even if sensory cue is novel. It is successful method to combine use of neurotracor to label projection neurons to striatum with juxtacelluar recording/labeling method.
