Newly formed emotional memories can be erased from the human brain.The findings may represent a breakthrough in research on memory and fear. This is shown by researchers from Uppsala University in a study being published by Science.
Contrary to the prevailing theories that music and language are cognitively separate or that music is a byproduct of language, theorists at Rice University’s Shepherd School of Music and the University of Maryland, College Park (UMCP) advocate that music underlies the ability to acquire language.
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.
Have you ever wondered why some people find it so much easier to stop smoking than others? New research shows that vulnerability to smoking addiction is shaped by our genes.
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.
Frequently, as many as one thousand signals rain down on a single neuron simultaneously. To ensure that precise signals are delivered, the brain possesses a sophisticated inhibitory system. Scientists have now illuminated how this system works.
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 identified a potential medical treatment for cognitive effects of stress-related disorders, including post-traumatic stress disorder (PTSD). The study, conducted in a PTSD mouse model, shows that an experimental drug called S107, one of a new class of small-molecule compounds called Rycals, prevented learning and memory deficits associated with stress-related disorders.
Neuroscientists have believed that three brain regions are critical for self-awareness: the insular cortex, the anterior cingulate cortex, and the medial prefrontal cortex. Patient R is helping a research team show that self-awareness is more a product of a diffuse patchwork of pathways in the brain—including other regions—rather than confined to specific areas.
