People who hear voices that other people can't hear may use unusual skills when their brains process new sounds, according to research led by Durham University and University College London (UCL).
A theory that has gained considerable attention in international media, including Newsweek and the CBS broadcast 60 minutes, suggest that antidepressant drugs, such as the SSRIs, do not exert any actual antidepressant effect. A research group at the Sahlgrenska Academy has now analyzed data from clinical trials and can rebut this theory.
Knowing whether to stay in or leave a romantic relationship is often an agonizing experience and that ambivalence can have negative consequences for health and well-being. Now a new study offers insights into what people are deliberating about and what makes the decision so difficult, which could help therapists working with couples and stimulate further research into the decision-making process.
Young people between the ages of 15 and 30 living with a chronic illness are three times more likely to attempt suicide than their healthy peers, according to a new study from the University of Waterloo.
Neuroscientists who study memory have long believed that when we recall an event, our brains turn on the same hippocampal circuit that was activated when the memory was originally formed. However, MIT neuroscientists have now shown, for the first time, that recalling a memory requires a 'detour' circuit that branches off from the original memory circuit.
Researchers at the University of California, Riverside have devised a method to selectively erase particular fear memories by weakening the connections between neurons involved in forming these memories. In their experiments, they found that fear memory can be manipulated in such a way that some beneficial memories are retained while others, detrimental to our daily life, are suppressed. The research, done using a mouse model, offers insights into how PTSD/specific phobias may be better treated.
The human brain has a region of cells responsible for linking sensory cues to actions and behaviors and cataloging the link as a memory. Cells that form these links have been deemed highly stable and fixed. Now, the findings of a Harvard Medical School study conducted in mice challenge that model, revealing that the neurons responsible for such tasks may be less stable, yet more flexible than previously believed.
According to new research from the RIKEN-MIT Center for Neural Circuit Genetics, experiencing something and remembering it later is not a neural 'direct flight.' The pathway in the brain's hippocampus that underlies long-term memory formation contains at least one 'stopover' that is important specifically for retrieving episodic, personally experienced memories. This is in contrast to known direct memory circuits that pass through the hippocampus. This detour may be involved in quickly updating memories and responding to instinctual fears via hormonal release.
According to new research by Kalina Michalska, assistant professor of psychology at the University of California, Riverside, we now know that anxious children tend to avoid making eye contact, and this has consequences for how they experience fear. The shorter and less frequently they look at the eyes of others, the more likely they are to be afraid of them, even when there may be no reason to be.
In recent years, the Veterans Administration (VA) Healthcare System has expanded its efforts to target groups of veterans facing disparities in healthcare access and outcomes. An update on research toward advancing equitable healthcare for all veterans is presented in a September supplement to Medical Care, published by Wolters Kluwer.
