Sentence examples for index pupil from inspiring English sources

Thus, it is somewhat unclear under what circumstances BOLD signal activation in the amygdala might index pupil constriction.

This was done to index pupil activity related to emotional arousal, independent of cognitive demands (in a manner similar to the one used by Bradley et al., 2008).

No significant correlations were observed between proactive indices and pupil activity in the pretrial period in either the reward or emotion session.

Alongside the AICs role in performance monitoring, a great deal of evidence has been provided implicating it as a correlate of autonomic nervous system (ANS) activity, ranging from heart beat to indices of pupil diameter (Craig 2002, 2009; Critchley 2005).

Conclusion: Automated infrared pupillometry, and particularly the quantitative Neurological Pupil index, may be useful for early neuroprognostication in VA-ECMO patients.

Patients and methods: Preliminary cohort analysis (June 2016-August 2017) of consecutive patients with VA-ECMO, in whom Npi®-200 pupillometer (Neuroptics®, USA) was repeatedly performed (12 72 h) to measure  % pupillary light response (qPLR) and Neurologic Pupil index (NPi).

Subsequently, the theoretical prediction of the counter defocus was calculated by the following equation [ 49]: where δ l is the pseudo focal shift from the focal plane, c is dioptric power, n is the refractive index, R is pupil radius, and Z 2 0 is the Zernike coefficient of defocus.

For example, a preliminary study indicated the possibility of discriminating patients (TMD or patients with obstructive sleep apnea syndrome, OSAS) from a control group investigating linear and RQA pupil indexes [ 43].

However we also examined the relation between average EDA values and average values on our other indices during the pupil calibration checks, which were presented towards the middle and end of the testing session, and found similarly low levels of agreement, which seemingly precludes this explanation.

This could be tested through psychophysiological measures that are thought to more directly index conditioning effects, such as pupil dilation, heart rate and skin conductance.

The concept of 'added value' was introduced to the UK school system in 2002 to overcome the issues of using 'raw' school attainment as a measure of school performance, because raw achievement is largely an index of the calibre of pupil intake, rather than any indication of the school's performance [1], [20].
