When a cocaine addict relapses, it isn't a matter of personal failure—it's the biological result of their brain's rewiring, ...

Scientists identify the protein DeltaFosB as the "master switch" that rewires the brain's memory and reward circuits, driving chronic cocaine addiction and relapse.

What Is the Limbic System? The limbic system is a part of the brain consisting of several components such as the hippocampus and amygdala and serving many functions within the body. While we have a ...

In a recent study published in Neuronal Psychiatry, researchers explored the molecular and cellular processes regulated by tissue inhibitor of metalloproteinases-2 (TIMP2) in the extracellular matrix ...

While neurogenesis—the growth of new brain cells—typically slows with age, superagers produce new neurons in the hippocampus at twice the rate of healthy older adults. In contrast, individuals with ...

The hippocampus plays a role in the brain's ability to learn and remember. In the Early Edition of the Proceedings of the National Academy of Sciences, Mody et al. report the use of a microarray ...

A. Overview of hippocampal dynamics during movie watching. FMRI data from the hippocampus were measured at the voxel level, and low-dimensional subspaces for two types of novelty and memorability were ...
