New study “Reward Association Enhances Stimulus-Specific Representations in Primary Visual Cortex.” has been recently released last month in Current Biology. Henschke and her colleagues demonstrated that the association of a reward with a repetitive visual stimulus over 5 consecutive days resulted in an enhanced representation of the reward-associated stimulus in mouse V1 layer 2/3 neurons, while responses to other stimuli were unaffected. They did sophisticated behavior experiments like random, uncoupled and goal-oriented water reward with VR system during locomotion in a learning paradigm.

They performed two-photon resonant calcium imaging and used Jet Ball System from #PhenoSys.

The study is open access: https://www.cell.com/current-biology/pdf/S0960-9822(20)30356-0.pdf
