The effects of spectrum, irradiance, and duration of exposure on light‐induced melatonin suppression in healthy adults

open access: yesPhotochemistry and Photobiology, EarlyView.
The left panel reports the measured time course data of melatonin concentration in the blood plasma of 17 BL‐Rs and 15 BL‐NRs at baseline, during a two‐hour stay in the dark, during a one‐hour light exposure to blue light, and again in the dark. The right panel shows the magnitude of melatonin concentration after 60 min of exposure to warm white, cool ...

Lack of Effect of Chlordiazepoxide on the Number of Falls in a Novel Falling‐Trap Test in Male C57BL/6N Mice

open access: yesNeuropsychopharmacology Reports, Volume 46, Issue 3, September 2026.
We developed a simple falling‐trap test to examine whether the number of falls could serve as an index of anxiety‐like behavior. The test is designed to produce falls from an elevated path, based on the hypothesis that less‐anxious mice would be more prone to fall. ABSTRACT Behavioral tests in mice and other animals are widely used to study anxiety and
