Daily Neuroscience for 16 April follows 4 stories from r/neuro and r/neuroscience, moving through predictive categories, psychosis mri models, action cognitive maps, astrocyte plasticity.

1. Predictive Categories

This story is about a Nature Reviews Neuroscience paper arguing that categorization is not just a final step after perception, but something the brain builds in from the beginning. The article says the brain groups objects, organisms, actions, and events into usable categories throughout signal processing, using predictive feedback to shape how incoming information is organized.

2. Psychosis MRI Models

This story is about a Nature paper on connectome-based predictive models that use MRI data to estimate cognition in people with early psychosis. The study trained models on 93 patients and tested them in an independent sample of 20, finding moderate accuracy for predicting general and fluid cognition.

3. Action Cognitive Maps

This story is about how the hippocampus, entorhinal cortex, and motor planning areas work together to represent action plans and their outcomes, based on a study in Nature Communications. In an immersive virtual reality task, people learned abstract two-dimensional motor action-outcome associations while undergoing fMRI.

4. Astrocyte Plasticity

This story is about how astrocytes help shape critical-period plasticity in the developing brain, based on a review in Current Opinion in Neurobiology through ScienceDirect. The review argues that these glial cells are not just supporting actors; they appear to help determine when developmental windows for learning and circuit refinement open, how strong they become, and when they close.
