(Asian) eyes with dilating, constricting, and static medium-sized pupils. Our results show that, independent of race, infants' pupils dilated more when viewing eyes with dynamically changing (dilating and constricting) pupils than when viewing eyes with non-changing, static, and medium-sized ...
We measured 9-month-old infants’ brain responses to dilating and constricting pupils in the context of viewing own-race and other-race eyes using functional near-infrared spectroscopy (fNIRS). Our results show that only when responding to own-race eyes, infants’ brains distinguished between ...
use causes constricted pupils, or the characteristic “pinpoint pupils” that medical textbooks describe -->The pupil acts as an aperture, dilating and constricting to allow light to let us see -->This blog consists of photos of things I find of interest, mainly from in and around Baltimore...
Normally the size of the pupil is the same in each eye, with both eyes dilating or constricting together. The termanisocoriarefers to pupils that are different sizes at the same time. The presence of anisocoria can be normal (physiologic), or it can be a sign of an underlying medical cond...
Results showed that (a) participants trusted partners with dilating pupils and withheld trust from partners with constricting pupils, (b) participants' pupils mimicked changes in their partners' pupils, and (c) dilation mimicry predicted trust in in-group partners, whereas constriction mimicry did ...
The iris is a rounded disc of individually varying color: it surrounds the pupil and regulates the amount of light entering the eye by constricting the pupil (sphincter pupillae muscle) or dilating it (dilatator pupillae muscle). Both muscles arise from the ectoderm. The sphincter pupillae mus...
7 are taken at about 600 milliseconds after onset of the flash of light from pupillometer 10 (or from onset of video recording without a flash of light) as the pupils 20L and 20R are dilating. There is some minor difference as depicted in the graph below the images of the pupils 20L...
It is available in a 0.5% solution to partially counteract, or reverse, the dilation effect of phenylephrine, an adrenergic dilating agent, and the dilating and accommodation loss caused by tropicamide. In addition to producing redness upon instillation, dapiprazole has very little effect on pupil ...
Here, we examined whether and how race impacts the neural processing of others' pupillary changes in early ontogeny. We measured 9-month-old infants' brain responses to dilating and constricting pupils in the context of viewing own-race and other-race eyes using functional near-infrared ...
Mammalian pupils respond to light 1 , 2 and dilate with arousal, attention, cognitive workload, and emotions, 3 thus reflecting the state of the brain. Pupil size also varies during sleep, constricting during deep non-REM sleep 4-7 and dilating slightly during REM sleep. 4-6 Anecdotal ...
