Operational implications of varying ambient light levels and time-of-day effects on saccadic velocity and pupillary light reflex

Autor: Edwin R. Hotchkiss, Minzhong Yu, Maria L. Thomas, Michael B. Russo, Mary A. Kautz, Dagny Johnson

Publikováno v: Ophthalmic and Physiological Optics. 27:130-141

Changes in maximal saccadic velocity (SV), initial pupil diameter (IPD), constriction latency (CL) and constriction amplitude (CA) determined by the pupillary light reflex have been found to be sensitive indicators of impairment as a result of drugs,

Neural basis of alertness and cognitive performance impairments during sleepiness II. Effects of 48 and 72 h of sleep deprivation on waking human regional brain activity

Autor: Kathryn A. Popp, Maria L. Thomas, Helen S. Mayberg, David R. Thorne, Daniel P. Redmond, Helen C. Sing, Gregory Belenky, Laura M. Rowland, A. Welsh, Robert F. Dannals, Henry N. Wagner, Sharon M. Balwinski, Henry H. Holcomb

Publikováno v: Thalamus & Related Systems. 2:199-229

Sleep deprivation impairs alertness and cognitive performance, and these deficits suggest decreases in brain activity and function, particularly in the prefrontal cortex, a region subserving alertness, attention, and higher-order cognitive processes

Publikováno v: Journal of Sleep Research. 12:1-12

Daytime performance changes were examined during chronic sleep restriction or augmentation and following subsequent recovery sleep. Sixty-six normal volunteers spent either 3 (n = 18), 5 (n= 16), 7 (n = 16), or 9 h (n = 16) daily time in bed (TIB) fo

Publikováno v: Journal of Sleep Research. 9:335-352

The negative effects of sleep deprivation on alertness and cognitive performance suggest decreases in brain activity and function, primarily in the thalamus, a subcortical structure involved in alertness and attention, and in the prefrontal cortex, a

The Effects of L-Dihydroxyphenylalanine on Alertness and Mood in α-Methyl-Para-Tyrosine-Treated Healthy Humans Further Evidence for the Role of Catecholamines in Arousal and Anxiety

Autor: Warren Avery, David R. Thorne, Martica H. Hall, Gregory Belenky, Helen C. Sing, Kathy Popp, Maria L. Thomas, Una D. McCann

Publikováno v: Neuropsychopharmacology. 13:41-52

Treatment with alpha-methyl-para-tyrosine (AMPT), a catecholamine synthesis inhibitor, has been shown to produce pronounced increases in sleepiness and mild increases in negative mood and anxiety when administered to healthy male adults. The present
