Mesencephalic projections to the nucleus accumbens shell modulate value updating during probabilistic reversal learning

This study shows that optogenetic stimulation of VTA to NAcbS projections impairs reversal learning and increases exploitation bias in rats during probabilistic reversal learning.

Sleep-insomnia superposition: opposing brain signatures of sleep in task-based and resting-state conditions

The paper examines correlations between task and resting-state brain signatures of sleep, cognition, and depression in over 30,000 individuals, revealing opposing neural patterns associated with insomnia and depression.

Neurobehavioral precursors of compulsive cocaine-seeking in dual fronto-striatal circuits

The paper identifies neurobehavioral markers in rats that predict future compulsive cocaine seeking behavior through pre-existing functional and structural brain changes.

Functional connectivity between the entorhinal and posterior cingulate cortices associated with navigation impairment following path integration in at-genetic-risk Alzheimer’s disease

The paper assesses navigation impairments in at-genetic-risk Alzheimer’s disease using the Virtual Supermarket Test and finds reduced functional connectivity between the entorhinal and posterior cingulate cortices in the APOE e4 group.
