Manipulation Of Specific Neurons Helps To Erase Bad Memories

Imagine if memory could be tuned in such a way where good memories are enhanced for those suffering from dementia or bad memories are wiped away for individuals with post-traumatic stress disorder. A Stony Brook University research team has taken a step toward the possibility of tuning the strength of memory by manipulating one of the brain’s natural mechanisms for signaling involved in memory, a neurotransmitter called acetylcholine. Their findings are published in the journal Neuron.

Brain mechanisms underlying memory are not well understood, but most scientists believe that the region of the brain most involved in emotional memory is the amygdala. Acetylcholine is delivered to the amygdala by cholinergic neurons that reside in the base of the brain. These same neurons appear to be affected early in cognitive decline. Previous research has suggested that cholinergic input to the amygdala appears to strengthen emotional memories.

[...] In the paper, titled “Cholinergic Signaling Controls Conditioned Fear Behaviors and Enhances Plasticity of Cortical-Amygdala Circuits,” Dr. Role and colleagues used a fear-based memory model in mice to test the underlying mechanism of memory because fear is a strong and emotionally charged experience.[...]

Animation explanation: Nineteenth century psychologist, Herman Ebbinghaus, demonstrated that we normally forget 40% of new material with the first twenty minutes, a phenomenon known as the forgetting curve. But this loss can be prevented through memory consolidation, the process by which information is moved from our fleeting short-term memory to our more durable long-term memory, thanks to the hippocampus…and a good night’s sleep!
