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.

How can neurotransmitters inhibit or excite a postsynaptic neurons?
Inhibit it by hyper polarizing the membrane or excite it by bringing the voltage closer to the threshold potential.
What are the chemicals that are released at an axon terminal and can either excite or inhibit other neurons called?
These are called neurotransmitters.
What is the most important function of endorphins?
Enable neurons to excite or inhibit each other
What is the energy supply for photosynthesis?
sunlight to excite the electrons
What is needed to excite electrons?
For example when the electron absorb energy.

During photosynthesis visible light has enough energy to?
Excite electrons
What does psychostimulant mean?
Psycho = brain stimulate = to excite so it would mean to stimulate or excite the brain. Good examples would be methamphetamine, amphetamine, cocaine and the like. I suppose you could also qualify anti-depressants as psychostimulants because they enhance neurotransmitters, thus increasing brain activity.
What happens when pigments absorb light?
the electrons of the pigment molecules excite, then the energy dissipates as heat.
If electromagnetic forces were somehow increased equally would it take more energy to excite atoms?
Specifically would an object with said increased electromagnetic bonds etc. exhibit appearances of being colder than they actually were due to the increased energy required to excite them?
What does the word excitable mean?
Excite is a verb meaning "to raise an emotional response, usually of happiness or joy". In science, the verb excite means "to raise the energy level of, generally in reference to an electron".
What does the process of transmitting a nerve impulse from one neuron to another involve?
When a neurotransmitter lands on their receptor site, they can either excite of inhibit the receiving cell. To excite a cell, positive sodium ions flow to it, which depolarizes the membrane in a similar way to a nerve impulse. The depolarizing effect spreads through the membrane and only last for 1/3 of a millisecond.
How do you write excite in Spanish?
entusiasmar = to excite
