Brain circuits convert visual input into action via cortical hierarchies and basal ganglia loops.
Visual signals progress from V1 to V2, V4, and inferotemporal cortex. Prefrontal areas handle working memory and reward evaluation while parietal regions integrate context.
Basal ganglia loops with striatal D1 and D2 pathways, subthalamic nucleus, and dopaminergic input from SNc and VTA, via the thalamus, select actions. Part B shows encoding, transformation, reward evaluation, decoding, and motor processing under working memory. These models help refine deep brain stimulation for Parkinson's disease.

Emotions are fundamental to human life, but when dysregulated, they can contribute to anxiety and trauma-related mood disorders.
In a new #SciencePerspective, researchers dive into new approaches to understand emotions across species and how these insights could be used to advance treatments for psychiatric disorders.
