What is the action of dopamine on the postsynaptic membrane?
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.
What messages does GABA send to a receiving neuron?
GABA sends inhibitory messages to the receiving neuron, which help to regulate neuronal activity by reducing the likelihood of the receiving neuron to generate an action potential. This can lead to a calming effect on the nervous system and help maintain the balance of excitation and inhibition in the brain.
What are excitatory postsynaptic potentials are produced by?
Excitatory postsynaptic potentials (EPSPs) are typically produced by the influx of positively charged ions, such as sodium or calcium, into the postsynaptic neuron. This influx of ions depolarizes the neuron, making it more likely to fire an action potential. EPSPs are a key mechanism in the communication between neurons in the nervous system.
What are neurotransmitters for postsynaptic neuron?
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.
What are the synaptic events?
Synaptic events refer to the processes involved in communication between neurons at synapses. These events include neurotransmitter release from the presynaptic neuron, binding of neurotransmitters to receptors on the postsynaptic neuron, and subsequent changes in the postsynaptic neuron's membrane potential. This can lead to excitation or inhibition of the postsynaptic neuron based on the type of neurotransmitter and receptors involved.
What determines the effect that a neurotransmitter has on the postsynaptic neuron?
the receptors on the postsynaptic membrane

What happens when neurotransmitters communicate an excitatory message to the postsynaptic neuron?
When neurotransmitters communicate an inhibitory message to the postsynaptic neuron:

What is a presynaptic neuron?
a neuron from the axon terminal of which an electrical impulse is transmitted across a synaptic cleft to the cell body or one or more dendrites of a postsynaptic neuron by the release of a chemical neurotransmitter.
When does a postsynaptic potential occur?
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.
What is the name of the tiny gap the neurotransmitter has to diffuse across to reach the membrane of the postsynaptic neuron?
The tiny gap that the neurotransmitter has to diffuse across to reach the membrane of the postsynaptic neuron is called the synaptic cleft. It separates the axon terminal of the presynaptic neuron from the dendrite of the postsynaptic neuron.
Neurotransmitters find their way to and subsequently trigger firing of that neuron?
Excitatory neurotransmitter

When two or more presynaptic neurons synapse with a single postsynaptic neuron in the CNS what pathway is formed?
When two or more presynaptic neurons synapse with a single postsynaptic neuron in the central nervous system (CNS), it forms a convergent pathway. This allows for integration of multiple inputs onto a single neuron, influencing the postsynaptic neuron's response.
What are the synaptic events?
Synaptic events refer to the processes involved in communication between neurons at synapses. These events include neurotransmitter release from the presynaptic neuron, binding of neurotransmitters to receptors on the postsynaptic neuron, and subsequent changes in the postsynaptic neuron's membrane potential. This can lead to excitation or inhibition of the postsynaptic neuron based on the type of neurotransmitter and receptors involved.
