INDIANAPOLIS: Memories lost due to traumatic brain injury, stress, or diseases such as Alzheimer’s may be retrieved by activating brain cells with light, shows a promising study.
Neuroscience researchers have for many years debated whether retrograde amnesia, which follows traumatic injury, stress, or diseases such as Alzheimer’s, is caused by damage to specific brain cells, meaning a memory cannot be stored, or if access to that memory is somehow blocked, preventing its recall.
“The majority of researchers have favored the storage theory, but we have shown in this paper that this majority theory is probably wrong,” said…
