Modulatory role of serotonergic system on visual responses of excitatory and inhibitory neurons in layer I and II/III of primary visual cortex, an optogenetic and in vivo whole-cell patch-clamp study

Goal: Because of complexities of 5-HT function in cortical networks we would like to measure exact subthreshold and supra threshold responses of different excitatory and inhibitory neurons in primary visual cortex (V1) to different orientations and contrasts.
