… required genetically engineering the mice so that their neurons could be controlled by light from a fiber optic … cells accelerated fear extinction and suppressing the neurons made fear extinction harder, demonstrating that … among neurons. Yet another theory focuses on the inhibitory neurotransmitter GABA, suggesting that reduced …

… called astrocytes are about as abundant in the brain as neurons, but scientists have spent much less time figuring … the chemical conditions necessary for groups of neurons to team up to encode information. Specifically, the … about the movies lab mice were seeing. GABA is a common inhibitory neurotransmitter that sharpens neural activity and …

Inhibitory neurons constantly remodeled connections with their excitatory partners. Inhibitory synaptic connections had never been visualized …

… circumstances, these chemicals steer the activity of neurons to produce and sustain relatively long-lasting … it uses a burst of endocannabinoids to quiet down inhibitory signals that would otherwise come from another … she’ll knock out the endocannabinoid receptors on the inhibitory cells and see what difference that makes to the …
