Amnesia is a fixable result of retrieval impairment, not damage
MIT researchers have found they were able to reactivate memories in mice that could not otherwise be retrieved, using optogenetics — in which proteins are added to neurons to allow them to be activated with light. The breakthrough finding, in a paper published Thursday (May 28) in the journal Science, appears to answer a longstanding question … more…

Light electric stimulation of the brain may improve memory for people with schizophrenia
May 29, 2015

Transcranial direct-current stimulation device (credit: GoFlow) Lightly stimulating the brain with transcranial direct current stimulation (tDCS) may improve short-term memory in people with schizophrenia, according to a new study by researchers at the Johns Hopkins University School of Medicine. The tDCS procedure involves placing sponge-covered electrodes on the head and passing a weak electrical current between them. David Schretlen, Ph.D., a … more…
