- synaptic transmission
- nerve impulse travels down the axon
- it reaches the pre synaptic terminal
- this triggers the releaseof neuro transmitters
- they are fired into the synaptic cleft
- neuro transmitters bind with receptors on the dendrite of the adjacent neuron
- if successfully transmitted the neuro transmitter is taken up by the post synaptic neuron
- the message will continue via electrical impulses
- if successfully transmitted the neuro transmitter is taken up by the post synaptic neuron
- neuro transmitters bind with receptors on the dendrite of the adjacent neuron
- they are fired into the synaptic cleft
- this triggers the releaseof neuro transmitters
- it reaches the pre synaptic terminal
- action potential
- occurs when a neuron sends information down an axon away from the cell body
- it's an explosion of electrical activity
- a stimulus causes the resting potential to move forward
- excitation and inhibition
- excitory= they will make it more likely the next neuron will fire e.g acetylcholine
- inhibitory= they will make it less likely that the next neuron will fire e.g GABA
- normal brain function depends on a regulated balance between excitory and inhibitory influence
- nerve impulse travels down the axon
