New research shows The amygdala helps choose between competing strategies when rewards are uncertain and decisions get confusing.
Neuron-powered computer chips can now be easily programmed to play a first-person shooter game, bringing biological computers a step closer to useful applications ...
The brain’s primitive “fear center” may be much more than that, as new research on the amygdala suggests it plays a crucial role in learning, emotion, and decision-making. Researchers from Dartmouth ...
Understanding how a healthy brain works can provide insight into how it fails, too. Scientists hope that studying organoids derived from humans with neurodevelopmental disorders — particularly ...
A Dartmouth study challenges the conventional view that the amygdala-the two-sided structure deep in the brain involved in emotion, learning, and decision making-is simply the brain's primitive "fear ...
Researchers find that the amygdala is a sophisticated mediator that chooses between action-based and stimulus-based learning ...
How we learn to predict an outcome isn’t determined by how many times a cue and reward happen together. Instead, how much ...
People with spinal cord injuries often lose movement even though their brains still send the right signals. Researchers tested whether EEG brain scans could capture those signals and reroute them to ...
They looked at the brain’s non-visual light-sensing system, driven by melanopsin-containing intrinsically photosensitive retinal ganglion cells (ipRGCs). Even though the photopigment melanopsin is in ...
Summary: A biologically grounded computational model built to mimic real neural circuits, not trained on animal data, learned a visual categorization task just as actual lab animals do, matching their ...
Researchers have created a protein that can detect the faint chemical signals neurons receive from other brain cells. By tracking glutamate in real time, scientists can finally see how neurons process ...
