Glutamate
Definition
Glutamate is an excitatory neurotransmitter that increases brain activity and plays a key role in learning and memory.
Analogy
If GABA is like brakes on a car, then glutamate would be like stepping on the gas pedal. It speeds up communication between neurons helping us think faster, learn new information, and form memories.
Related terms

NMDA Receptor: A receptor for glutamate that plays a key role in learning and memory formation when activated.
Long-Term Potentiation (LTP): This refers to a long-lasting increase in synaptic strength between two neurons resulting from their simultaneous activation. LTP is thought to be one mechanism by which memories are stored.
