Molecular Power Behind Memory Discovered

Neuroscientists have long wondered how individual connections between brain cells remain diverse and "fit" enough for storing new memories. Reported in the science journalNeuron, a new study led by Dr. Inna Slutsky (heh – sorry! – PD) of the Sackler School of Medicine at Tel Aviv University describes what makes some memories stick.

The key is GABA (γ-Aminobutyric acid), a natural molecule that occurs in the brain, which could be the main factor in regulating how many new memories we can...
