IBS scientists control memory by modulating synchronized brain waves during deep sleep

Have you ever tried to recall something just before going to sleep and then wake up with the memory fresh in your mind? While we absorb so much information during the day consciously or unconsciously, it is during shut eye that a lot of facts are dispatched to be filed away or fall into oblivion.

Study provides greater understanding of psychology behind fear

What happens in the brain when we see other people experiencing a trauma or being subjected to pain? Well, the same regions that are involved when we feel pain ourselves are also activated when we observe other people who appear to be going through some painful experience.

Shutting down key protein could slow or prevent Alzheimer’s disease, study shows

In experiments with a protein called Ephexin5 that appears to be elevated in the brain cells of Alzheimer's disease patients and mouse models of the disease, Johns Hopkins researchers say removing it prevents animals from developing Alzheimer's characteristic memory losses.

Alcohol strengthens emotional memories linked to fearful experiences, study shows

Experiments in mice by researchers at Johns Hopkins suggest that if the goal is to ease or extinguish fearful emotional memories like those associated with post-traumatic stress disorder, alcohol may make things worse, not better.

New suite of sensors can help monitor patients to prevent heart failure events

A suite of sensors can predict heart failure events by detecting when a patient's condition is worsening, according to Dr. John Boehmer, professor of medicine, Penn State College of Medicine, who presented the findings at the American Heart Association annual meeting in New Orleans.

Transplant drug rapamycin may reduce nerve damage, neuropathic pain after spinal cord injury

New research in mice indicates that a drug commonly used to suppress the immune system in recipients of organ transplants may also reduce tissue damage and neuropathic pain after spinal cord injury. The findings are published in the Journal of Orthopaedic Research.

Study finds decreased habenula activity in people with depression

A region of the brain that responds to bad experiences has the opposite reaction to expectations of aversive events in people with depression compared to healthy adults, finds a new UCL study funded by the Medical Research Council.

Uncertainty can lead to significantly more stress, study finds

Knowing that there is a small chance of getting a painful electric shock can lead to significantly more stress than knowing that you will definitely be shocked, finds a new UCL study funded by the Medical Research Council .

Aggression influences new nerve cell production in the brain

A group of neurobiologists from Russia and the USA, including Dmitry Smagin, Tatyana Michurina, and Grigori Enikolopov from Moscow Institute of Physics and Technology, have proven experimentally that aggression has an influence on the production of new nerve cells in the brain.

Brain regions cause PTSD patients to generalize non-threatening events

Regions of the brain function differently among people with post-traumatic stress disorder, causing them to generalize non-threatening events as if they were the original trauma, according to new research from Duke Medicine and the Durham VA Medical Center.

Higher nurse staffing levels and better working conditions improve survival following IHCA

Patients with in-hospital cardiac arrest (IHCA) have low survival rates--but why do some hospitals achieve higher survival than others? Higher nurse staffing levels and better working conditions may be part of the answer, reports a study in the January issue of Medical Care.

Scientists discover special brain mechanism that can retrieve unconscious memories

Some stressful experiences - such as chronic childhood abuse - are so overwhelming and traumatic, the memories hide like a shadow in the brain.

Study on marine snails could help better understand underlying mechanisms of age-related memory loss

A new research study on marine snails uncovered the first cells in the nervous system to fail during aging. The University of Miami Rosenstiel School of Marine and Atmospheric Science researchers' findings are important to better understanding the underlying mechanisms of age-related memory loss in humans.

Cortisol study may explain persistence of emotional memories occurring in anxiety, PTSD

The stress hormone cortisol strengthens memories of scary experiences. However, it is effective not only while the memory is being formed for the first time, but also later when people look back at an experience while the memory reconsolidates. This has been published by cognition psychologists from the Ruhr-Universität Bochum in the journal "Neuropsychopharmacology".
