Electrical Signalling
Occurs within a neuron
To achieve rapid, long-distance communication
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
