Molecular Mechanism of Synaptic Function
Action potentials
Crosses the synapse
Crosses 3 neurons
Calcium ions into the nerve terminal.
Activates neurotransmitters, they release their content.
One activates receptors on target neurons.
Lets sodium ions in
Information transfers from one neuron to the other.
The Cochlea
