Researchers have identified a pre-programmed neural circuit in the basolateral amygdala of mice that processes both positive and negative stimuli.
Newly formed emotional memories can be erased from the human brain.The findings may represent a breakthrough in research on memory and fear. This is shown by researchers from Uppsala University in a study being published by Science.
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.
In order to recover from phobias, researchers suggest people must alter memory driven negative attitudes about their feared object.
According to a new study, fear memory encoding is influences by parvalbumin interneurons in the amygdala.
Coupling training to reduce fear and transplanting embryonic interneurons into the amygdala of mice, researchers were able to reduce fear response, a new study reports.
