One
What is excitation?
Increase of positive charge causing the neuron to fire
In it’s resting state, how is a neuron charged?
Negatively
What is an inhibitory neurotransmitter?
A chemical that increases the negative charge of a neuron making it less likely to fire
What is summation?
The sum of all signals a neuron receives - it will either fire or not = ‘all or nothing’
