Finding a "face neuron" in an ANN doesn't mean it encodes faces like we do. 🧵 In my first project with @apurvaratan.bsky.social, we show that category selectivity in ANNs ≠ category selectivity in brains. Details in thread + preprint: www.biorxiv.org/content/10.6... Feedback or questions welcome!

Circuit mechanisms of psychotic symptoms across disorders
In this review, Braun et al. propose that psychotic symptoms across psychiatric and neurological disorders arise from disturbances in neuromodulatory systems that alter neural gain and precision weighting, destabilizing cortico-striato-thalamo-cortical circuits and large-scale brain networks, offering a transdiagnostic, testable framework for future research.
