Neurons eat glutamate to stay alive
... Glutamate is the most abundant excitatory neurotransmitter, but too much of it causes toxicity by overactivating postsynaptic receptors. When postsynaptic receptors are activated, the postsynaptic cytoplasmic calcium concentration rises, activating proteases, lipases, and endonucleases, causing cell ...
