Alzheimer; News from the web:
The writer of the post in our link for today developed an approach that allowed us to activate the neurons that store memory information, referred to as memory engrams, through optogenetics—that is, introducing a gene that is light sensitive into the memory engram cells of “Alzheimer’s” mice, then delivering blue light pulses to activate them—and measuring memory recall strength directly. To our surprise, we found comparable numbers of engram cells in normal healthy animals and Alzheimer’s animals, suggesting that the initial memory storage process is intact. Targeting the recall process in Alzheimer’s animals led to an improvement in their memory, which reached the performance level of normal animals.
