#cortical — Public Fediverse posts

🧠 New preprint by Garcia-Garcia et al.: The authors show that cerebellar #GranuleCells do not simply expand #cortical activity into a high-dimensional code. Instead, they preserve low-dimensional cortical #manifold geometry while reorienting it across contexts. This rotation separates similar tasks, reduces interference, and supports flexible dual-task learning.

Cortical development in #primates follows a hierarchical gradient, but how does this vary between species? This study shows that #humans & #macaques share conserved maturation patterns, with humans exhibiting prolonged #cortical development @PLOSBiology https://plos.io/4prEO65

🧠 New study by Lempel et al. (2025): Visual experience after eye opening aligns #feedforward inputs (L4) and #RecurrentNetworks (L2/3) in mouse #VisualCortex. This improved alignment, together with enhanced orientation discrimination, creates coherent, reliable sensory codes, revealing how experience shapes stable #cortical representations:

📚 New preprint by Song et al.: Geometry of #NeuralDynamics along the #cortical #attractor landscape reflects changes in attention. They show that while attractor positions are determined by cortical organization, the geometry of neural dynamics on the landscape changes systematically with attentional states and contexts.

Cortical thinning is associated with altered neurotransmission in young adults with a history of heavy drinking since adolescence

The article discusses a recent study conducted in Finland that explored the effects of #heavy #alcohol #consumption during #adolescence on #brain #development.

The study followed a group of young adults over a 10-year period, comparing those with a history of heavy drinking in adolescence to those who consumed little or no alcohol. The researchers found that the heavy-drinking group had #lower #cortical #gray #matter #thickness in several brain regions and #altered #neurotransmission compared to the control group.

Specifically, they observed increased activity in inhibitory neurotransmitters and thinner gray matter in the #frontal and #parietal lobes.

The study highlights the potential negative impact of heavy alcohol use during adolescence on brain structure and function, emphasizing the need for further research to understand the underlying mechanisms
