Web15 Feb 2024 · The cell that receives information is the postsynaptic neuron (i.e., receives chemical messages). Neurotransmitters are used by the nervous system to send signals between neurons and other cells. WebThis is known as a Inhibitory Postsynaptic Potential (IPSP) because it’s going to be LESS likely to throw off an action potential. Contrast that with exitatory NTs: All excitatory neurotransmitters cause an opening of ligand-gated sodium ion channels. The inhibitory NT could also cause an opening up of ligand-gated Chloride Ion channels.

WebSynapse The points of contact between neurons where information is transmitted from one neuron to the next are referred to as synapses. The majority of synapses use chemical messengers to communicate. Other synapses are electrical, and ions move directly between cells in these synapses. WebThe neurotransmitter binds to the neuroreceptors in the post-synaptic membrane, causing the channels to open. In the example shown these are sodium channels, so sodium ions flow in. 5. This causes a depolarisation of the post-synaptic cell membrane, which may initiate an action potential, if the threshold is reached. 6.
