What is the difference of Inhibitory postsynaptic potential vs antagonist?
In: Biology
Inhibitory potentials will cause the postsynaptic neuron to hyperpolarize, which essentially makes it harder for the postsynaptic neuron to send a signal. Keep in mind that most neurons have a lot of other neurons giving them signals, so the inhibitory signals are generally blocking signals from other pre-synaptic neurons and keeping them from activating the post-synaptic neuron.
An excitatory potential will depolarize the postsynaptic neuron, which will cause it to send a signal. It’s basically the standard process of how neurons are usually shown.
Excitatory post synaptic potentials make the neuron more likely to fire an action potential
Inhibitory post synaptic potentials make the neuron less likely to fire an action potential
EPSPs and IPSPs are weighed against each other to decide if a neuron fires or not.
An antagonist blocks the receptors on the neuron, making it so neither IPSPs or EPSPs can happen because the excitatory and inhibitory receptors are blocked
IPSPs try to stop the neuron from firing if there are more of them than EPSPs. Antagonists block excitation and inhibition from happening so there is no potential at all. There is just nothing, excitatory or inhibitory
