Endogenous recruitment of frontal-sensory circuits during visual discrimination

This is the authors' abstract. We don't add key points for this paper.

Summary A long-range circuit linking anterior cingulate cortex (ACC) to primary visual cortex (V1) has been previously proposed to mediate visual selective attention in mice during visually guided behaviour. Here we used in vivo two-photon functional imaging to measure endogenous activity of ACC neurons projecting to layer 1 of V1 (ACC-V1 axons ) in mice either passively viewing stimuli or performing a go/no-go visually guided task. We observed that while ACC-V1 axons were recruited under these conditions, this was not linked to enhancement of neural or behavioural measures of sensory coding. Instead, ACC-V1 axon activity was observed to be associated with licking behaviour, modulated by reward, and biased towards task relevant sensory cortex.
