All neurotransmitters have an effect on the post synaptic membrane of either inhibition or excitation. Dopamine is an Excitatory NT so if a Excitatory Neuron meets with another Excitatory Neuron it creates Excitation. However if it meets with an Inhibitory Neuron Dopamine and the other Excitatory NT's wll only create Inhibition. Only GABA and Glycine are considered Inhhibitory NTransmitters.
Neurotransmitters that bind to the postsynaptic membrane generate a response by either depolarizing or hyperpolarizing the postsynaptic neuron. This response can lead to the generation of an action potential if the threshold is reached, propagating the signal further along the neuron.
The presynaptic cell that must have action potentials to produce one or more action potentials in the postsynaptic cell is the neuron releasing neurotransmitters at the synapse. When an action potential reaches the presynaptic terminal, it triggers the release of neurotransmitters into the synaptic cleft, which then bind to receptors on the postsynaptic cell membrane, leading to the generation of an action potential in the postsynaptic cell.
Inhibitory neurotransmission results in hyperpolarization of the postsynaptic membrane by increasing the influx of negatively charged ions (e.g. chloride ions) or decreasing the influx of positively charged ions (e.g. potassium ions). This hyperpolarization makes it more difficult for the neuron to reach its threshold for firing an action potential, thus inhibiting the generation of an action potential in the postsynaptic neuron.
No, many neurotransmitters cause the postsynaptic membrane to be depolarized.
EPSP (excitatory postsynaptic potential) and IPSP (inhibitory postsynaptic potential) are two types of postsynaptic potentials that occur in neurons. EPSPs result from the binding of neurotransmitters that lead to depolarization of the postsynaptic membrane, making the neuron more likely to fire an action potential. In contrast, IPSPs are caused by neurotransmitters that hyperpolarize the postsynaptic membrane, decreasing the likelihood of action potential firing. Together, EPSPs and IPSPs regulate neuronal excitability and communication within the nervous system.

binds to specific receptors on the postsynaptic cell membrane, leading to changes in the cell's membrane potential. This can either excite or inhibit the postsynaptic neuron, influencing the likelihood of an action potential being generated. Ultimately, the effect of the neurotransmitter can influence the communication between neurons in the nervous system.
the receptors on the postsynaptic membrane
It can be an excitatory postsynaptic potential (EPSP) or an inhibitory postsynaptic potential (IPSP), depending on the synapse. The EPSP depolarizes the membrane, while the IPSP hyperpolarizes it.
A postsynaptic potential occurs when neurotransmitters released from the presynaptic neuron bind to receptors on the postsynaptic neuron, causing a change in its membrane potential. This change can be either depolarizing (excitatory) or hyperpolarizing (inhibitory), influencing the likelihood of the postsynaptic neuron firing an action potential.
Neurotransmitters are chemical messengers that transmit signals and information from the presynaptic neuron to the postsynaptic neuron at the synapse. They bind to receptors on the postsynaptic neuron, leading to changes in its membrane potential and triggering a new signal to be passed along the neural pathway. Some common neurotransmitters include acetylcholine, dopamine, serotonin, and glutamate.
EPSP stands for excitatory postsynaptic potential. It is a temporary depolarization of postsynaptic membrane potential caused by the flow of positively charged ions into the neuron, usually due to the binding of neurotransmitters to their receptors. EPSPs can help to trigger an action potential in the neuron.
When acetylcholine (ACh) receptors open, sodium ions (Na+) primarily flow into the postsynaptic membrane. This influx of positively charged sodium ions leads to depolarization, making the inside of the cell more positive. If the depolarization reaches a certain threshold, it can trigger an action potential in the postsynaptic neuron.
