Accommodation (vertebrate eye)

Accommodation is the process by which the vertebrate eye changes optical power to maintain a clear image or focus on an object as its distance varies.

See Pupillary response and Accommodation (vertebrate eye)

Accommodation reflex

The accommodation reflex (or accommodation-convergence reflex) is a reflex action of the eye, in response to focusing on a near object, then looking at a distant object (and vice versa), comprising coordinated changes in vergence, lens shape (accommodation) and pupil size.

See Pupillary response and Accommodation reflex

Adrenaline

Adrenaline, also known as epinephrine, is a hormone and medication which is involved in regulating visceral functions (e.g., respiration).

See Pupillary response and Adrenaline

Anisocoria

Anisocoria is a condition characterized by an unequal size of the eyes' pupils.

See Pupillary response and Anisocoria

Anticholinergic

Anticholinergics (anticholinergic agents) are substances that block the action of the acetylcholine (ACh) neurotransmitter at synapses in the central and peripheral nervous system.

See Pupillary response and Anticholinergic

Arousal

Arousal is the physiological and psychological state of being awoken or of sense organs stimulated to a point of perception.

See Pupillary response and Arousal

Classical conditioning

Classical conditioning (also respondent conditioning and Pavlovian conditioning) is a behavioral procedure in which a biologically potent stimulus (e.g. food, a puff of air on the eye, a potential rival) is paired with a neutral stimulus (e.g. the sound of a musical triangle).

See Pupillary response and Classical conditioning

Cocaine

Cocaine (from, from, ultimately from Quechua: kúka) is a tropane alkaloid that acts as a central nervous system (CNS) stimulant.

See Pupillary response and Cocaine

Cognitive load

In cognitive psychology, cognitive load refers to the amount of working memory resources used.

See Pupillary response and Cognitive load

Cycloplegia

Cycloplegia is paralysis of the ciliary muscle of the eye, resulting in a loss of accommodation.

See Pupillary response and Cycloplegia

Dilated fundus examination

Dilated fundus examination (DFE) is a diagnostic procedure that uses mydriatic eye drops to dilate or enlarge the pupil in order to obtain a better view of the fundus of the eye.

See Pupillary response and Dilated fundus examination

Fight-or-flight response

The fight-or-flight or the fight-flight-freeze-or-fawn (also called hyperarousal or the acute stress response) is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival.

See Pupillary response and Fight-or-flight response

Hallucinogen

Hallucinogens are a large and diverse class of psychoactive drugs that can produce altered states of consciousness characterized by major alterations in thought, mood, and perception as well as other changes.

See Pupillary response and Hallucinogen

Interest (emotion)

Interest is a feeling or emotion that causes attention to focus on an object, event, or process.

See Pupillary response and Interest (emotion)

Iris dilator muscle

The iris dilator muscle (pupil dilator muscle, pupillary dilator, radial muscle of iris, radiating fibers), is a smooth muscle of the eye, running radially in the iris and therefore fit as a dilator.

See Pupillary response and Iris dilator muscle

Iris sphincter muscle

The iris sphincter muscle (pupillary sphincter, pupillary constrictor, circular muscle of iris, circular fibers) is a muscle in the part of the eye called the iris.

See Pupillary response and Iris sphincter muscle

Locus coeruleus

The locus coeruleus (LC), also spelled locus caeruleus or locus ceruleus, is a nucleus in the pons of the brainstem involved with physiological responses to stress and panic.

See Pupillary response and Locus coeruleus

LSD

Lysergic acid diethylamide, commonly known as LSD (from German Lysergsäure-diethylamid), and known colloquially as acid or lucy, is a potent psychedelic drug.

See Pupillary response and LSD

MDMA

3,4-Methylenedioxymethamphetamine (MDMA), commonly known as ecstasy (tablet form), and molly or mandy (crystal form), is a potent empathogen–entactogen with stimulant and minor psychedelic properties.

See Pupillary response and MDMA

Miosis

Miosis, or myosis, is excessive constriction of the pupil.

See Pupillary response and Miosis

Mydriasis

Mydriasis is the dilation of the pupil, usually having a non-physiological cause, or sometimes a physiological pupillary response.

See Pupillary response and Mydriasis

Neurotransmitter

A neurotransmitter is a signaling molecule secreted by a neuron to affect another cell across a synapse.

See Pupillary response and Neurotransmitter

Oculomotor nerve

The oculomotor nerve, also known as the third cranial nerve, cranial nerve III, or simply CN III, is a cranial nerve that enters the orbit through the superior orbital fissure and innervates extraocular muscles that enable most movements of the eye and that raise the eyelid.

See Pupillary response and Oculomotor nerve

Ophthalmology

Ophthalmology is a clinical and surgical specialty within medicine that deals with the diagnosis and treatment of eye disorders.

See Pupillary response and Ophthalmology

Opiate

An opiate is an alkaloid substance derived from opium (or poppy straw).

See Pupillary response and Opiate

Opioid

Opioids are a class of drugs that derive from, or mimic, natural substances found in the opium poppy plant.

See Pupillary response and Opioid

Optic nerve

In neuroanatomy, the optic nerve, also known as the second cranial nerve, cranial nerve II, or simply CN II, is a paired cranial nerve that transmits visual information from the retina to the brain.

See Pupillary response and Optic nerve

Parasympathetic nervous system

The parasympathetic nervous system (PSNS) is one of the three divisions of the autonomic nervous system, the others being the sympathetic nervous system and the enteric nervous system.

See Pupillary response and Parasympathetic nervous system

Physiology

Physiology is the scientific study of functions and mechanisms in a living system.

See Pupillary response and Physiology

Pupil

The pupil is a hole located in the center of the iris of the eye that allows light to strike the retina.

See Pupillary response and Pupil

Pupillary light reflex

The pupillary light reflex (PLR) or photopupillary reflex is a reflex that controls the diameter of the pupil, in response to the intensity (luminance) of light that falls on the retinal ganglion cells of the retina in the back of the eye, thereby assisting in adaptation of vision to various levels of lightness/darkness. Pupillary response and pupillary light reflex are pupil.

See Pupillary response and Pupillary light reflex

Pupillary reflex

Pupillary reflex refers to one of the reflexes associated with pupillary function.

See Pupillary response and Pupillary reflex

Pupillary response

Pupillary response is a physiological response that varies the size of the pupil, via the optic and oculomotor cranial nerve. Pupillary response and Pupillary response are pupil and sexual arousal.

See Pupillary response and Pupillary response

Pupillometry

Pupillometry, the measurement of pupil size and reactivity, is a key part of the clinical neurological exam for patients with a wide variety of neurological injuries.

See Pupillary response and Pupillometry

Pupilometer

Pupillometer, also spelled pupilometer, is a medical device intended to measure by reflected light the size of the pupil of the eye.

See Pupillary response and Pupilometer

Rapid eye movement sleep

Rapid eye movement sleep (REM sleep or REMS) is a unique phase of sleep in mammals (including humans) and birds, characterized by random rapid movement of the eyes, accompanied by low muscle tone throughout the body, and the propensity of the sleeper to dream vividly.

See Pupillary response and Rapid eye movement sleep

Sexual arousal

Sexual arousal (also known as sexual excitement) describes the physiological and psychological responses in preparation for sexual intercourse or when exposed to sexual stimuli.

Substituted amphetamine

Substituted amphetamines are a class of compounds based upon the amphetamine structure; it includes all derivative compounds which are formed by replacing, or substituting, one or more hydrogen atoms in the amphetamine core structure with substituents.
