How chronic early-life stress raises PTSD vulnerability

Medical researchers may have discovered how chronic stress experienced early in life increases vulnerability to post-traumatic stress disorder later in life.

Thin, flexible polymers record ‘conversations’ deeper in the brain with less injury-risk

Researchers have developed thin, flexible polymer-based materials for use in microelectrode arrays that record activity more deeply in the brain and with more specific placement.

Babies make the link between emotions expressed vocally and facially

The ability of babies to differentiate emotional expressions appears to develop during their first six months. But do they really recognize emotion or do they only distinguish the physical characteristics of faces and voices? Researchers have just prov…

Brain combats dementia by shifting resources

The brain continues to put up a fight even as neurodegenerative diseases like dementia damage certain areas and functions. In fact, recent findings in a Baycrest-University of Arizona study suggest that one method the brain uses to counter these diseas…

An immunological memory in the brain

Inflammatory reactions can change the brain’s immune cells in the long term — meaning that these cells have an ‘immunological memory.’ This memory may influence the progression of neurological disorders that occur later in life, and is therefore a pre…

Mutant ferrets offer clues to human brain size

Scientists have engineered ferrets genetically to study abnormally small brain size in humans — and, in the process, discovered hints as to how our brains evolved.

The neural circuitry of parental behavior

Scientists have deconstructed the brain circuits that control parenting behavior in mice, and identified discrete sets of cells that control actions, motivations, and hormonal changes involved in nurturing young animals.

Brain activity can predict success of depression treatment

Researchers believe they have uncovered a method that could be useful in predicting a depressed patient’s treatment prognosis, prior to starting treatment.

Discovery could let doctors customize brain’s immune response to diseases

The neuroscience lab that discovered that the brain connects directly to the immune system now has found evidence that doctors could load up the brain with custom blends of immune cells to battle genetic disorders and neurodegenerative diseases such as…

Wildfire smoke associated with more ER visits for heart, stroke ailments among seniors

Exposure to smoke from wildfires was associated with increased rates of emergency room visits for heart- and stroke-related illness, especially among adults age 65 and older.
