Hippocampus Rewires Memories to Predict Future Rewards

A preclinical study shows the hippocampus actively reorganizes memories to forecast rewards, with hippocampal neurons shifting their activity from the moment of reward to earlier task features as mice learn. Using long-term calcium imaging, researchers tracked cells over weeks, revealing a predictive, backward-shifting signal that refines the brain’s internal model of outcomes and offering a new lens on learning—and why decision-making falters early in Alzheimer's disease.

Ultrasound Techniques Enhance Brain Reward Systems Rapidly

Researchers used non-invasive transcranial ultrasound stimulation to target the nucleus accumbens, a deep brain structure involved in motivation, and found it enhanced reward learning in humans within 60 seconds, suggesting potential for treating mental health disorders without surgery.

"The Cerebellum's Impact on Learning and Autism Unveiled"

A study by researchers at the University of Pittsburgh and Columbia University reveals that the cerebellum, traditionally associated with motor control, also plays a crucial role in reward-based learning and forming new visuomotor associations. By training monkeys to associate visual cues with hand movements for rewards, the study shows that blocking a specific region of the cerebellum impairs the ability to learn new associations, highlighting its contribution to cognitive functions. This discovery expands our understanding of the cerebellum's role beyond motor control and offers insights into addressing non-motor symptoms in individuals with cerebellar disorders.
