Researchers reveal how the olfactory system aids in threat assessment and have identified neurons that learn whether a specific smell represents a threat.
Some patients diagnosed with behavioral-variant frontotemporal dementia (bv-FTD) may instead be suffering from a cerebrospinal fluid leak that leads to brain sagging.
Postmortem brains of those with schizophrenia have fewer genes associated with 12-hour activity cycles in the dorsolateral prefrontal cortex. Mitochondrial-related genes in the dlPFC did maintain a 12-hour rhythm, but their activity did not peak at normal times.
The activation of dentate granule cells in the hippocampus plays a key role in alterations that occur during the development of post-traumatic epilepsy.
Frequent moderate to vigorous exercise is linked to better cognition and brain power during middle age. This intensity level was associated with better working memory and mental processes. Reducing the intensity to lower intensity or sedentary behavior for 6-7 minutes per day was associated with poorer cognitive performance.
Injecting the brain molecule into mouse models of multiple sclerosis increased the number of oligodendrocytes. The findings suggest fractalkine may help to slow the progression, or potentially halt multiple sclerosis.
Anhedonia and depression arise when POMC neurons in the arcuate nucleus of the hypothalamus become hyperactive as a result of chronic stress. Reducing the activity also reduces feelings of depression and loss of pleasure.
Teenagers who suffer from inadequate or disrupted sleep may be at higher risk of developing multiple sclerosis later in life.
Many say reading a good book can help us to process complex emotions, but is that really the case? Researchers investigate how cathartic reading can be.
While pet dogs and pet pigs pay their owners a similar amount of attention, when it comes to pointing to the location of an out-of-range treat, only dogs direct their owner's attention to the location. Findings suggest directing human attention to an interesting location is not ubiquitous in domesticated animals.
When teaching a child to read, giving them challenges individually adapted to their levels is most effective.
Researchers say mindfulness meditation has benefits for adolescents who have experienced trauma.
