New research reveals that Type 2 diabetes may impair the brain’s reward and memory processing in ways that mirror early Alzheimer’s disease.

Type 2 diabetes may quietly alter the brain in ways that mimic early Alzheimer’s, weakening reward perception and memory ...

All rats pursued rewards, but areas where rewards were received were less salient to those with T2D; these rats had weaker ACC reward signals in these locations and did not stay there long.

Hippocampal replay, which is implicated in memory formation and planning, exhibits a reward-dependent spatial specificity that in novel environments requires dopamine signaling.

In a study in the Journal of Affective Disorders, Fralin Biomedical Research Institute scientists Pearl Chiu and Brooks Casas investigate how brain signals involved in reward learning might help ...

Learning theory states that we learn that a stimulus is paired with a reward only if, initially, we don't expect it — there must be a 'prediction error' for learning to occur. Now Waelti et al.

We're all familiar with Pavlovian conditioning, in which a reward-anticipatory behavior follows a reward-predicting stimulus. Perhaps you experience it yourself when passing a café or restaurant and ...

The signals in the anterior putamen exhibited a positive response to the unpredicted reward, while those in the caudate head showed a weak response. This is significant because the dorsal striatum ...
