- Ions: Na+, K+, Ca2+, Cl-, A-
- Movement across plasma membrane allows electrical signalling to occur
- In action potentials, it conveys info
- Neurotoxins (tetrodotoxin) help us understand
the role of ion channels in electrical signalling
- Cannot cross the chemical synapse (break in
electrical circuit)
- Converted into chemical signal, to link action
potential of 1 neuron to synaptic potential of other
- Can cross electrical synapse
- Converted into chemical signal, to link action
