Modeling Human Pupil Dilation to Decouple the Pupillary Light Reflex

open access: yesOpen Physics, 2019
The aim of this paper is to present methods to calculate pupil size based on various parameters, such as: luminance, age, corneal flux density or monocular/binocular effect.

The Pupillary Light Reflex in Postgeniculate Lesions

open access: yes, 1993
This study was undertaken to investigate the effect of postgeniculate lesions on the pupillary light reflex. The pupil responses to focal, hemifield, and full field light stimuli were recorded in 5 patients with occipital lobe infarcts.

Infant Pupil Diameter Changes in Response to Others' Positive and Negative Emotions. [PDF]

open access: yes, 2011
It has been suggested that infants resonate emotionally to others' positive and negative affect displays, and that these responses become stronger towards emotions with negative valence around the age of 12-months.

Characteristics of the Pupillary Light Reflex in the Macaque Monkey: Metrics

open access: yes, 2000
To investigate whether the simian light reflex is a reasonable model for the human light reflex, we elicited pupillary responses in three behaving rhesus macaques. We measured the change in pupillary area in response to brief (100 ms), intermediate (1 s)

Pupil size modulation drives retinal activity in mice and shapes human perception

open access: yesNature Communications
Retinal adaptation is assisted by the pupil, with pupil contraction and dilation thought to prevent global light changes from triggering neuronal activity in the retina.

The neural substrate for the pupillary light reflex in the pigeon (Columba livia)

open access: yes, 1984
The neural substrate of the pupillary light reflex in the pigeon was investigated using anatomical, stimulation, and lesion techniques. In birds, as in mammals, the sphincter pupillae muscle (which constricts the iris) is innervated by cells in the ...
