Ahn suffers a brain injury that causes the release of a specific neurotransmitter in staggering amounts. The result is that her neurons fire off a frenzy of nonstop action potentials in a cascading sequence that may, in time, become fatal. What neurotransmitter has been affected by this injury?

Acetylcholine

Explanation:

A neurotransmitter are neuron generated chemical message carriers that transmits signals over the synaptic cleft

The neurons releases neurotransmitters as a response to a presynaptic neuron axon terminal depolarization

Neurotransmitters function by exciting or inhibiting a response when they are bound to post-synaptic cell receptors thereby based on the the kind of post-synaptic cell can lead to an array of response

Acetylcholine is a neurotransmitter released at the junctions between nerves and muscles and aids in the initiating contraction of the muscles

Excessive stimulation by Acetylcholine due to lack of removal from the synapses can be fatal.
