New role for brain’s support cells in controlling circadian rhythms

A new study has found that astrocytes, previously thought of as just supporting neurons in regulating circadian rhythms, can actually lead the tempo of the body’s internal clock and have been shown for the first time to be able to control patterns of d…

Neuroimaging shows social exclusion spurs extremism in those vulnerable to radicalization

A new study used neuroimaging techniques to show that social exclusion increases the number of ideological and group values worth fighting and dying for in populations vulnerable to radicalization. The study focused on neural activity in a region of th…

Scientists harness machine learning to uncover new insights into the human brain

An inter-disciplinary research team has successfully employed machine learning to uncover new insights into the cellular architecture of the human brain. This approach could potentially be used to assess treatment of neurological disorders, and to deve…

Newly discovered leukodystrophy in children: Potential cure

Medical researchers have uncovered a novel disease of children affecting the brain white matter — the myelin sheath –, leading to severe incapacity and death in some cases. These defects were corrected by a treatment with fingolimod, a drug in use fo…

Raising histamine levels boosts long-term memory

According to a recent Japanese study, boosting histamine levels in the brain can significantly improve performance in long-term memory tests.

Excessive body fat around the middle linked to smaller brain size, study finds

Carrying extra body fat, especially around the middle, may be linked to brain shrinkage, according to new research. For the study, researchers determined obesity by measuring body mass index (BMI) and waist-to-hip ratio in study participants and found …

Decreased deep sleep linked to early signs of Alzheimer’s disease

Researchers have uncovered part of the explanation for why poor sleep is linked to Alzheimer’s disease. They found that older people who have less slow-wave sleep – the deep sleep you need to consolidate memories and wake up feeling refreshed – hav…

Genes on the move help nose make sense of scents

With today’s study, researchers have pinpointed a genomic mechanism by which a finite number of genes can ultimately help distinguish a seemingly near-infinite number of scents.

How words get an emotional meaning

Everyday objects and people have an emotional meaning. A wool sock might have an emotional value if it was the last thing grandmother knitted before her death. The same applies to words. A stranger’s name has no emotional value, but if a loving relatio…

Brain plasticity restored in adult mice through targeting specific nerve cell connections

Research in mice finds a new molecular mechanism that is essential for maturation of brain function and may be used to restore plasticity in aged brains. Unlike previous research that broadly manipulated brain plasticity and affected the entire brain, …
