Researchers Discover Idling Brain Activity in Severely Brain Injured Patients Who “Wake Up” After Using a Sleep Drug
Researchers discover a signature of brain activity in some severely brain injured patients, who regained some consciousness after using certain drug treatments.
Researchers find definitive brain alterations in veterans with GWI, caused as the result of exposure to neurotoxic chemicals during the first Gulf War. The study confirms working memory is affected in those with GWI.
Researchers have identified a group of proteins essential to the formation of long-term memories.
Researchers discover a low dose of psilocybin erased conditioned fear responses in mice. They suggest the agent could be a potential treatment for PTSD and related conditions.
Researchers identify the sleep mechanism which enables the brain to consolidate emotional memory. Additionally, they discovered a popular sleep medication heightens the response to and recollection of negative memories.
By watching individual neurons at work, a group of psychologists at the University of Wisconsin-Madison has revealed just how stress can addle the mind, as well as how neurons in the brain’s prefrontal cortex help remember information in the first place.
Researchers have discovered how to store diverse forms of artificial short-term memories in isolated brain tissue. Using isolated pieces of rodent brain tissue, the researchers demonstrated that they could form a memory of which one of four input pathways was activated.
Scientists found that adverse listening situations are difficult for the brain, partly because they draw on the same, limited resources supporting our short-term memory. The new findings are particularly relevant to understanding the cognitive consequences of hearing damage, a condition that affects an increasing number of people.
Researchers recently localised and identified the most important types of nerve cells involved in forming positive and negative memories of a fruit fly. All four nerve cell types they discovered use dopamine to communicate with other nerve cells. Three of the nerve cell types assume various functions in mediating negative stimuli, while the fourth enables the fly to form positive memories.
Study shows intact memory for familiar information, despite memory deficit A 22-year-old woman known as “HC” with amnesia since birth as a result of developing only half the normal volume of the hippocampus in her brain, has demonstrated to scientists that the ability to hold a single face or word in short-term memory is impaired.
