Weekly Neuroscience Update

Granule cells connect with other cells via long projections (dendrites). The actual junctions (synapses) are located on thorn-like protuberances called “spines”. Spines are shown in green in the computer reconstruction Credit DZNE/Michaela Müller.

New findings on the link between nerve cells at the interface to the hippocampus may have an influence on learning and memory.

People choosing between two or more equally positive outcomes experience paradoxical feelings of pleasure and anxiety, feelings associated with activity in different regions of the brain, according to research at the Princeton Neuroscience Institute at Princeton University.

Latest findings on how stress hormones promote the brain’s building of negative memories.

Researchers have studied the changes in the brain that are associated with impulsiveness, a personality trait that causes difficulties in inhibiting a response in the face of a stimulus and leads to unplanned actions without considering the negative consequences. These patterns can serve as an indicator for predicting the risk of behavioural problems.

People taking dopamine for Parkinson’s disease sometimes begin to generate a lot of artwork. New research differentiates their expressiveness from obsessive or impulsive tendencies.

Researchers have uncovered more than 100 genetic markers linked to developing schizophrenia.

A type of immune cell widely believed to exacerbate chronic adult brain diseases, such as Alzheimer’s disease and multiple sclerosis (MS), can actually protect the brain from traumatic brain injury (TBI) and may slow the progression of neurodegenerative diseases, according to research published in the online journal Nature Communications.
