PSYC324_12_Pupil_Dilation

Pupil dilation ______ due to fatiguepupil dilation ______ during a task in a manner similar (but the reverse of) the EMG gradientPupil dilation ____ in response to pain PD Increased with increasing intensity of electric shockwomen had higher pain tolerance than kmen

Pupil dilation _____ when people are thinking hard aversive pictures cause momentary pupil dilation followed by constriction

Pupil dilation is related to_________

Pupil constricting response to bright light differentiate patients that will have schizophrenic episodes during drug-free period and those that won't.Those that relapse have ____ pupil constrictionthe pupils of people with schizophrenia don't ____ as much during cognitively demanding tasks as the pupils of people without schizophrenia

Factors that increase the phasic pupil response also increase the ____________ phasic pupil dilation is _____, sudden dilation in the absence of lighting changes, and is referred to as the PDR

The PDR does not include dilation to which is not a phasic (short-term) response

The PDR is sensitive to

The locus coeruleus demonstrates two types of firing______ is base finding rate chanes slowly, sleep/wake cycle, arousal and vigilance______ is rapid-onset, brief increase in firing to specific stimulus/event: enhanced in signal to noise ratio in cortex

Recordings form monkeys: changes in _______ _____ correlate with tonic firing of ____

Spontaneous and drug-induced drowsiness and other low-arousal states, which are characterized by low tonic LC activity, reduces __________

Noradrenergic drugs that _____ arousal and_____ LC activity also______ baseline pupil diameter

Task processing is accompanied by rapid and dramatic________which is consistent with the occurrence of an LC phasic response to task-relevant events

Both the LC and the SNS receive _____ projections coming form a common source: the________

The PDR may be used to assess ______ activity

________ may track instantaneous LC activity, such that baseline pupil diameter corresponds to ________firing rate, and task-evoked dilations correspond to ______ activity
