I am not an expert in this field, but we did study psychiatric disorders recently in my nursing classes. The neurotransmitter serotonin controls mood and sleep (among other things), and when you decrease its levels (or if uptake is blocked), people end up with clinical depression. Antidepressants work to increase serotonin (or increase its uptake). Also, GABA (gamma-Aminobutyric acid) is an inhibitory neurotransmitter that regulates excitability in the nervous system. So if there is too little GABA present, the hormones that cause excitability run wild and you end up with anxiety (overstimulation). Anxiolytics (anti-anxiety meds) work to increase GABA, which inhibits that excitabililty and slows those anxious feelings.
Neurotransmitters are the chemicals released at an axon terminal that can either excite or inhibit other neurons. They help transmit signals across the synapses between neurons in the nervous system. Examples of neurotransmitters include dopamine, serotonin, and GABA.
Neurotransmitters can inhibit a postsynaptic neuron by binding to inhibitory receptors, which can open channels that allow negatively charged ions like chloride to enter the neuron, making it more negative and less likely to fire. On the other hand, neurotransmitters can excite a postsynaptic neuron by binding to excitatory receptors, leading to the opening of channels that allow positively charged ions like sodium to enter the neuron, depolarizing it and increasing the likelihood of firing an action potential.
Neurotransmitters are released from the presynaptic neuron into the synaptic cleft, where they diffuse across to bind to receptors on the postsynaptic neuron. This binding initiates a series of events that can either excite or inhibit the postsynaptic neuron, leading to the transmission of signals in the nervous system.
Neurotransmitter receptors are located on the postsynaptic membrane of neurons. When a neurotransmitter binds to its specific receptor, it can either excite or inhibit the postsynaptic neuron, thereby influencing the transmission of signals in the brain.

Neurotransmitters bind to specific proteins on the postsynaptic membrane called receptors. These receptors initiate a series of events that can either excite or inhibit the firing of the postsynaptic neuron.

after impulse conductionby postsynaptic neurons is initiated, neurotransmitters activity is rapidly terminated. Either one or both of two mechanisms cause this. Some neurotransmitters molecules difuseout of the synaptic cleft back into synaptic knobs
Yes, neurotransmitters are sometimes referred to as "keys" because they play a critical role in transmitting signals between nerve cells, or neurons. These molecules bind to specific receptors on the surface of neurons, which triggers a response in the receiving cell. Just like a key fits into a lock to open a door, neurotransmitters bind to receptors to either excite or inhibit activity in the brain and body.
The cell body fires when it receives enough input signals, usually in the form of neurotransmitters from other neurons. These signals can excite or inhibit the cell body, changing its membrane potential until it reaches a threshold that triggers an action potential.

Yes, that is correct. A postsynaptic potential is a localized change in the membrane potential of a postsynaptic neuron in response to neurotransmitters binding to receptors on its membrane. This results in a graded potential that can either excite or inhibit the postsynaptic neuron's firing.
The energy required to excite an electron from the ground state to an excited state with an energy level of 13.6 eV is 13.6 electron volts.
