"Neural stem cells seem to be particularly interested in the chemical GABA (gamma-aminobutyric acid) a neurotransmitter thats known to be involved in inhibiting signals from other neurons. When scientists artificially block these stem cells GABA receptors from receiving messages, the cells wake up and start replicating but when those GABA signals are allowed to reach the receptors, the stem cells stay dormant.
In this case, Song explains, GABA communication keeps the brain stem cells in reserve, so if we dont need them, we dont use them up.
In short, leaky synapses arent wasteful as a matter of fact, theyre essential to the brains self-sculpting abilities."
And also, how does taking a daily benzo affect this communication?When I had no roof I made Audacity my roof.-Robert Pinsky
