How widespread are our memories stored in the brain? .Our new study, open access in @NatureNeuro, investigates how category learning changes neuronal representations in mouse visual cortical areas. (1/8).@mpi_neuro @sandra_tanja @t_bonhoeffer @MHuebener .

Starting in a couple of minutes, don’t miss it 😊 @sandra_tanja @MPIforBI.

In case you haven't seen it yet, the poster session still lasts another 45 minutes! Great work from @daniellepaynter @MPIforBI.

In summary, category learning changed many aspects of neuronal coding in visual areas, with area POR most prominently shifting from visual feature to category tuning. Thus, semantic aspects of learned categories can already be identified in visual areas of the mouse brain. (8/8).

Of course, many neurons responded already selectively to stimulus properties before learning. Using the GLM kernels, we disentangled tuning for visual features (orientation/spatial freq) from tuning for categories. Area POR showed the strongest increase in category tuning. (7/8)

Using an encoding model (GLM), we found that, across areas, the newly responsive neurons encoded choice behavior and reward. (6/8)
