Neurons & Neurotransmitters A typical neuron

The importance of binding sites on receptors
By attaching to receptor binding sites
N-Ts cause structures in walls of the
axon to open (gates or “ion channels””)
allows electrically charged particles (ions) to flow
into neuron >> alters electrical activity in neuron
Positively charged particles stimulate neuron
(moved towards firing)
Negatively charged particles inhibit it (prevent
it from firing)

here is what causes
ion channel to open]
