متن کاملReflex excitability regulates prepulse inhibition.
Presentation of a weak stimulus, a prepulse, before a reflex-evoking stimulus decreases the amplitude of the reflex response relative to reflex amplitude evoked without a preceding prepulse. For example, presenting a brief tone before a trigeminal blink-eliciting stimulus significantly reduces reflex blink amplitude. A common explanation of such data are that sensory processing of the prepulse ...

vasovagal syncope or neurocardiogenic syncope refers to the loss of consciousness that occurs secondary to hypotension resulting in reduced blood supply to the brain. it is the most common form of unexplained syncope (50-60%) in the outpatient setting. Bradycardia and vasodilation are the primary causes of this hypotension. fear, pain, dehydration, alcohol consumption, anxiety, tight clothing a...
متن کاملThe oculorespiratory cardiac reflex in the dog.
Intraorbital and intracranial electrical stimulation as compared with manual eye pressure indicates that in the dog the afferent pathway for the oculorespiratory cardiac reflex is carried by the ophthalmic division of the fifth cranial nerve. The effects on cardiac and respiratory arrythmia produced by using intravenous atropine have demonstrated that, although reflex bradycardia can be abolish...
