通过利用大脑的电磁特性或将放射性标记物送入体内,神经科学家利用大脑成像技术来创建神经元活动和生理过程的详细图片。然后,他们可以分析大脑功能的测量值在不同情况下的变化--当人们被促使以某种方式进行行为、思考或感觉时,或者它们在不同个体之间的变化。在这样做的过程中,研究人员获得了有关大脑运作及其与精神疾病...
Indeed, it has been shown that spontaneous activity modulates variability in task-induced activity in sensory cortices19,20,21,22,23. The brain’s spontaneous activity as measured in the resting state (when a participant is awake but not involved in a specific task) shows a complex temporal ...
TCF/LEF reporter activity was measured in HEK293 cells and concentrations of each compound that produce 50% activation (EC50) are shown. (c) Activity of CHIR99021 in the TCF/LEF reporter assay in HEK293 and HT-22 cells. TCF/LEF luciferase reporter activity was measured by Dual-Glo assay ...
Activity is displayed starting 1 s prior to odor-port-exit (odor sampling) and 1 s following. The positive odors are plotted in blue and the negative odors are plotted in red. Trials are shown blocked for visualization purposes; these trials occurred pseudo-randomly. (F) Same as in (E),...
Aim: To describe objectively measured physical activity level, cardiorespiratory fitness and diabetes risk in a group of Pakistani immigrant men living in Oslo, Norway. Methods: One hundred and fifty Pakistani immigrant men in the age group 25-60 years were included. Physical activity level was ...
Active leisure and in-school PA included strolling, gymnastics, track and field, martial arts, and ball games; active travel included walking and cycling; and domestic PA included cleaning the house, doing laundry, cooking, and buying food. Sedentary behaviors were measured as the average weekly ...

The δ13Corg content within the kerogen was measured using a stable isotope mass spectrometer (ThermoFinigan Delta Plus XL) with a precision better than ± 0.1‰. The carbon isotope values are given in per mille relative to VPDB. For hydrocarbon extraction and GC–MS analysis, the powders ...
1d for the speed distribution of a single particle measured in orbit for ≈4 min (>1200 frames). For swimmers on circular posts, the (arc) displacement was obtained according to Fig. 3a. On the peanut-shaped posts, distances were obtained using the NIS-Elements Advance Research software ...
Brain activation was measured in 63 healthy participants, before and after the walk, using a fearful faces task and a social stress task. Our findings reveal that amygdala activation decreases after the walk in nature, whereas it remains stable after the walk in an urban environment. These ...
