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

In case you haven't seen it yet, the poster session still lasts another 45 minutes! Great work from @daniellepaynter @MPIforBI
I get to present our poster about two-timeframe monosynaptic rabies tracing and visual system plasticity this afternoon (Wednesday) at #FENS2024, PS02-26PM-137. Come by! 😊😊 @MPIforBI @t_bonhoeffer @MHuebener @xpieter

Scientists of Twitter! The world needs more reminders that we're living, breathing human beings. I was tempted to post a picture of me doing not-science, but my spouse confirmed that no one wants to see a picture of me napping on a weekend afternoon.

Join us tomorrow for two SWC Seminars! At 10am in-person and online, Dr Pieter Goltstein (@xpieter, @MPIforBI) will speak about how category-defining associations are represented in the brain: https://t.co/faC83y8pnt 1/2

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)
