Hallucinations are sensory perceptions that appear in the absence of stimuli. Although they are often associated with illnesses such as schizophrenia, these phenomena can occur in the absence of mental ill health. But what explains these uncanny occurrences? Not all hallucinations occur due to psychotic disorders or psychedelic drugs. There are many types of hallucinations....

Transcranial stimulation to prevent fear memories from returning

by University of Bologna research group from the University of Bologna has succeeded in modifying the negative effect of a returning memory that triggers fear, and developed a new non-invasive experimental protocol. The result of this study, published in the journal Current Biology, is an innovative protocol that combines fear conditioning—a stimulus associated with something...

Calcium channel subunits play a major role in autistic disorders

by Universitaet Mainz After 21 days in vitro, hippocampal neurons of the rat form many synaptic contacts and communicate with each other. Within the study such neuronal networks cultivated on multi-electrode arrays were used to invest the synaptogenic function of α2δ-subunits. Credit: ill. by Artur Bikbaev The ability of the human brain to process and...

Breakthrough image shows how “super-ager” brains resist cognitive decline

By Rich Haridy July 15, 2020 New research is illustrating the differences in toxic protein accumulations in the brains of older subjects suffering cognitive decline compared to older subjects with unexpectedly strong cognitive abilities. An image compiled from PET scans of these so-called “super-agers” has won Image of the Year from the Society of Nuclear...
