excitatory and inhibitory

what is excitatory

* nt eg noradrenaline are the nervous systems ‘on switches’
* these inc likelihood that postsynaptic cell will fire

what is inhibitory

* neurotransmitters (e.g. GABA) are nervous system ‘of switch’
* makes postsynaptic cell less likely to fire.

explain excitatory processes

For example, if an ^^excitatory neurotransmitter^^ like noradrenaline ^^binds to the post-synaptic^^ ^^receptors^^ it will cause an ^^electrical charge in the cell membrane^^ which results in an ^^**excitatory post-synaptic potential (EPSP)**^^**,** which makes the post-synaptic cell ^^more likely to fire^^.

explain inhibitory process

Whereas, if an %%inhibitory neurotransmitter%% like GABA %%binds to the post-synaptic receptors%% it will result in an %%**inhibitory post-synaptic potential (IPSP)**%%**,** which makes the post-synaptic cell %%less%% %%likely to fire.%%
