How diverse brain cells reach a decision together

Researchers found that individual neurons have perplexingly complex responses, but their activity is shaped by a shared structure that ultimately guides the brain toward a unified choice. The findings offer deeper insight into fundamental brain function and how it goes awry in disorders such as schizophrenia or bipolar disorder.

How the brain remembers what gave you food poisoning

Princeton neuroscientists pinpoint the central amygdala as the brain region responsible for forming lasting memories of food poisoning, which may shed light on PTSD and inform future clinical treatments. The study found that novel flavors can 'tag' specific brain cells to remain sensitive to illness signals.

Princeton neuroscientists crack the code of how we make decisions

A new mathematical model sheds light on how the brain processes different cues during decision making, potentially improving treatment for neurological disorders like Alzheimer's. The latent circuit model proposes a 'low-dimensional' mechanism that explains decision-making in large neural networks.
