Definition of excitatory in English: excitatoryadjective ɪkˈsʌɪtət(ə)riɛkˈsʌɪtət(ə)riikˈsīdəˌtôrē Physiology Characterized by, causing, or constituting excitation. 〔主生理〕刺激（或兴奋）性的；有刺激（或兴奋）作用的 the excitatory action of these impulses 这些冲动的刺激作用。 Example sentencesExamples - The NMDA receptor is activated by glutamate, the primary excitatory neurotransmitter in the brain.
- However, in other cases, it may be associated with a biochemical and/or physiological defect in the brain of the patient with epilepsy presumably due to an imbalance of excitatory and inhibitory neurotransmitters.
- If an excitatory input, associated with hypoxia, was received by the respiratory motor centers in the brainstem, an increase in respiratory activity should have resulted.
- Two kinds of motor nerves, excitatory nerves that release acetylcholine and inhibitory nerves that release nitric oxide, account for all events that occur in smooth muscle of the esophagus in a swallow.
- Either of these receptors has an excitatory or inhibitory effect on the end organ.
- Ampakine drugs enhance excitatory communication, thereby partially or completely restoring the brains excitatory communication.
- In order to bring normal balance between excitatory and inhibitory postsynaptic potential, antiseizure drugs may use one or more of the following mechanisms.
- Glutamate, incidentally, is the workhorse excitatory transmitter for neurons in the brain.
- Neurosteroids can therefore alter neuronal excitability very rapidly by binding to receptors for inhibitory or excitatory neurotransmitters at the cell membrane.
- Norepinephrine and serotonin may be excitatory or inhibitory, but they are functionally inhibitory on pain transmission; glutamate is the other important excitatory neurotransmitter.
- The active transport mechanism for methylfolate across the blood-brain barrier strictly limits the entry of the vitamin, perhaps for reasons concerned with the excitatory properties of folic acid.
- In the brain, 80% of manganese is found in the enzyme glutamine synthetase, which inactivates the excitatory amino acid glutamate to glutamine.
- The responsible nerves appear to include both excitatory cholinergic fibers and inhibitory fibers that probably release nitric oxide.
- Spontaneous central excitatory phenomena and a reduction in flow demand help mitigate the effect of attenuation of chemical and neuromechanical compensatory responses that characterizes REM sleep.
- In the esophagus, most investigators have observed excitatory effects in the form of an increased incidence of nonpropulsive contractions or an increased contraction force.
- Verbal disapproval, when used alone, has been shown to increase noncompliance, and shouted commands often result in excitatory effects in preschoolers.
- The parasympathetic nervous system is excitatory and results in the contraction of smooth muscle, whereas the sympathetic system inhibits smooth muscle in the digestive system.
- The need to develop a medication that is consistently effective for cocaine abuse has brought attention to another class of agents called excitatory amino acid antagonists.
- In the heart, arrhythmias arise due to metabolic deficiencies; these are interpreted as originating directly from the excitatory muscle tissue sensitive to acidosis.
- The cells that responded to nerve stimulation were most likely principal neurons and not interneurons, because fast excitatory postsynaptic potentials were recorded in these cells.
