Is glutamate an excitatory or inhibitory neurotransmitter?

Glutamate is a small, amino acid neurotransmitter, and is the primary excitatory neurotransmitter at almost all synapses in the central nervous system. This molecule binds multiple postsynaptic receptors including the NMDA receptor, AMPA receptor, and kainate receptors.

Also, is glycine an inhibitory neurotransmitter?

As a neurotransmitter. Glycine is an inhibitory neurotransmitter in the central nervous system, especially in the spinal cord, brainstem, and retina. When glycine receptors are activated, chloride enters the neuron via ionotropic receptors, causing an Inhibitory postsynaptic potential (IPSP).

Is Dopamine an excitatory or inhibitory neurotransmitter?

Dopamine: Excitatory Neurotransmitter. Dopamine functions as both an inhibitory and excitatory neurotransmitter depending upon where in the brain and at which particular receptor site it binds to.

Is GABA an excitatory or inhibitory neurotransmitter?

GABA is the main inhibitory neurotransmitter in the adult brain. GABRA3 is a candidate gene for autism. Doctor Josh Dubnau explains that the genes active in different neurons can make them excitatory (e.g. glutamate) or inhibitory (e.g. GABA). These neurotransmitters are critical to learning.
