Neurons transmit signals/impulses to other nerve cells.

When depolarization reaches -55mV, neuron fires an action potential.

Synapses are gaps between neurons; impulses transmit across them through chemical/electrical signals.

Action potential causes neurotransmitter release into the synaptic cleft from vesicles in a presynaptic neuron.

Neurotransmitters bind to receptors on the postsynaptic neuron, triggering changes (e.g., opening ion channels).

Stimulates a neuron towards an action potential.

Reduces the probability of an action potential.

Changes in neural connections throughout life, including learning and recovery from damage.
