In nocturnal rodents, brain areas that promote wakefulness have a circadian pattern of neural activation that mirrors the sleep/wake cycle, with more neural activation during the active phase than during the rest phase. To investigate whether differences in temporal patterns of neural activity in wake-promoting regions contribute to differences in daily patterns of wakefulness between nocturnal and diurnal species, we assessed Fos expression patterns in the tuberomammillary (TMM), supramammillary (SUM), and raphe nuclei of male grass rats maintained in a 12:12 h light-dark cycle. Day-night profiles of Fos expression were observed in the ventral and dorsal TMM, in the SUM, …

Light influences the daily patterning of behavior by entraining circadian rhythms and through its acute effects on activity levels (masking). Mechanisms of entrainment are quite similar across species, but masking can be very different. Specifically, in diurnal species, light generally increases locomotor activity (positive masking), and in nocturnal ones, it generally suppresses it (negative masking). The intergeniculate leaflet (IGL), a subdivision of the lateral geniculate complex, receives direct retinal input and is reciprocally connected with the primary circadian clock, the suprachiasmatic nucleus (SCN). Here, we evaluated the influence of the IGL on masking and the circadian system in a diurnal …

Increasing emphasis on interprofessionalism and teamwork in healthcare renders psychologists’ collaborations critical and invites reexamination of psychologists’ roles related to medications. The Collaboration Level outlined by the APA’s Ad Hoc Task Force is more achievable and in synch with health reform than prescription privileges (RxP). RxP remains controversial due to training and safety concerns, lacking support from health professionals, psychologists, and consumers. Differences in educational preparation of psychologists relative to prescribing professionals are discussed. Enactment of only three of 170 RxP initiatives reveals RxP to be a costly, ineffectual agenda. Alternatives (e.g., integrated care, collaboration, telehealth) increase access without risks …
