A new paper by Aman Saleem in the Carandini lab finds that V1 activity is modulated not only by spatial position, but by the animal’s subjective experience of it’s position, tightly correlated with CA1 activity.
From the abstract…
… Neuronal populations in both CA1 and V1 encoded the animal’s position along the corridor, and the errors in their representations were correlated. Moreover, both representations reflected the animal’s subjective estimate of position, inferred from the animal’s licks, better than its actual position. When animals licked in a given location—whether correctly or incorrectly—neural populations in both V1 and CA1 placed the animal in the reward zone. …
