💁🏻‍♀️ TIL: Using ultra-thin Neuropixels probes, #Baylor College researchers found the #hippocampus processes #speech and predicts upcoming #words during #anesthesia. 🧠

Over 70% of #neurons distinguished unexpected #sounds from predictable ones. This challenges the idea that understanding #language requires consciousness. 😪

New paper by Maimon et al (Ulanovsky lab): recordings from #bats flying through tunnels up to 200 m reveal a sparse-to-dense transformation between #hippocampal #CA3 and #CA1.

In small environments, CA3 and CA1 #PlaceCells look similar. At large spatial scales, however, CA3 #neurons mostly show single, ultrasparse #PlaceFields, while CA1 neurons show dense multifield coding.

The #brain’s code seems to be in constant flux. #Neurons fire much more erratically than researchers thought. What does that mean for how the brain works?

🧠 New paper by Chiu et al: #SST #interneurons do not only suppress #dendritic signaling. Via tonic activation of α5 #GABA receptors, they can paradoxically enhance AP-evoked dendritic #CalciumSignaling in #cortical #pyramidal #neurons.

Mechanistically, tonic #GABA hyperpolarizes #dendrites & deinactivates low-threshold voltage-gated #calcium channels, increasing calcium influx and facilitating calcium-dependent inhibitory #SynapticPlasticity.
