Definitions:

Neurons Sensitivity

The capacity of neurons to respond to stimuli or changes in the environment, affecting how signals are transmitted through the nervous system.

Receptor Molecules

Molecules, usually found on cell surfaces, that recognize and bind to specific substances, triggering a response.

Neurotransmitter

A chemical substance that is released at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure.

Ligand-Gated Channels

Ion channels in cell membranes that open or close in response to the binding of a chemical signal (ligand), allowing ions to pass through the membrane.
