Using magnets to improve memory

The ability to remember sounds, and manipulate them in our minds, is incredibly important to our daily lives -- without it we would not be able to understand a sentence, or do simple arithmetic. New research is shedding light on how sound memory works in the brain, and is even demonstrating a means to improve it.

Study provides insights into how excess serotonin affects motivation

A new study in mice shows that increasing serotonin, one of the major mediators of brain communication, affects motivation - but only in certain circumstances. Furthermore, the study revealed that the short and long term effects of increased serotonin levels are opposed - a completely unforeseen property of this neurotransmitter's functional system.

UAB researchers discover novel underlying mechanism involved in anxiety disorders, PTSD

University of Alabama at Birmingham neurobiologist Lynn Dobrunz, Ph.D., has discovered a novel mechanism for how stress-induced anxiety — the type of experience that can produce post-traumatic stress disorder, or PTSD — affects circuit function in the hippocampus, the area of the brain where aversive memories are formed.

Johns Hopkins scientists find link between sleep/wake cycles and core body temperature

A clump of just a few thousand brain cells, no bigger than a mustard seed, controls the daily ebb and flow of most bodily processes in mammals -- sleep/wake cycles, most notably.
