Basic Mechanisms and Implications of Non-Photic Entrainment of Circadian Rhythmicity
Abstract
The studies showed that afternoon exposure to exercise increases TSH levels and tends to delay the onset of nocturnal TSH secretion on the following night, Analysis of the melatonin levels is under progress. Mr Trabb learned to recruit, screen and supervise research volunteers, to record EEG activity, and all the basic skills of clinical research. He also participated in studies examining the effects of carbohydrate intake on vigilance and performance. Mr Salchli was responsible for incorporating the new computerized data collection and analysis system into the laboratory. His computer skills were vital in allowing the laboratory to begin using this new system. He used this system to determine the phase, shifting effects of light pulses of varying intensity on the free-running circadian rhythm of locomotor activity in both young and old hamsters. He was able to demonstrate that old hamsters are about 20 times less sensitive to the effects of light on the circadian clock, despite there being little if any effect of age on the amount of light being transmitted through the eyes
