Proof it’s possible to enhance or suppress memories

Using optogenetics to stimulate different areas of the hippocampus has the ability to enhance or suppress memories in mice. The findings could have implications for suppressing memories associated with traumatic events in PTSD, and also in enhancing cognitive ability or improving memory for those with neurodegenerative diseases, in the future.

Estrogen Made by Neurons Important to Memory Making

Researchers report estrogen may play a significant role in synaptic plasticity and memory formation. The study reports mice whose neurons did not produce estrogen have impairments in spatial reference memories, recognition and contextual fear memories. Restoring estrogen levels assisted in reversing the memory impairments, the study revealed.
