However, blinking is not only dependent on dryness and/or irritation. [citation needed] A brain area, the globus pallidus of the basal ganglia, contains a blinking center that controls blinking. Nonetheless, the external stimuli are still involved. Blinking is linked with the extraocular muscles. Blinking is often concurrent with a shift in ...
Though one may think that the stimulus triggering blinking is dry or irritated eyes, it is most likely that it is controlled by a "blinking center" of the globus pallidus of the lenticular nucleus—a body of nerve cells between the base and outer surface of the brain. Nevertheless, external stimuli can contribute.
Flicker vertigo, sometimes called the Bucha effect, is "an imbalance in brain-cell activity caused by exposure to low-frequency flickering (or flashing) of a relatively bright light." [ 1 ] It is a disorientation -, vertigo -, and nausea -inducing effect of a strobe light flashing at 1 Hz to 20 Hz, approximately the frequency of human brainwaves .
The endocrine system is affected largely by many internal and external stimuli. One internal stimulus that causes hormone release is blood pressure. Hypotension, or low blood pressure, is a large driving force for the release of vasopressin, a hormone which causes the retention of water in the kidneys. This process also increases an individual ...
External inhibition was especially observed when the tone (external stimulus) was introduced during the acquisition phase, which was the interval right after the paired CS-UCS trials. The conditioned response, blinking reflex, was observed to be in decline (inhibited) compared to the rate during conditioning. [5]
The order in which stimuli are presented is an important factor in all forms of classical conditioning. Forward conditioning describes a presentation format in which the CS precedes the US in time. That is, from the perspective of the research subject, experiencing the US is contingent upon having just experienced the CS. EBC is usually, but ...
It's probably safe to say that we've already established that cats blink. However they don't quite do it in the same way that we do. Cats' eyes are largely similar to ours but with some ...
It can be difficult to distinguish and understand information when experiencing sensory overload. Even such meaningless stimuli such as white noise or flickering lights may induce sensory overload. [32] Sensory overload is common among consumers as many corporations compete with each other especially when advertising.
