Title Light as a modulator of cognitive brain function Type Journal Article
Year 2009 Publication Trends in Cognitive Sciences Abbreviated Journal Trends Cogn Sci
Volume 13 Issue 10 Pages 429-438
Keywords Human Health; Animals; Brain/anatomy & histology/*physiology; Brain Mapping; Circadian Rhythm/*physiology; Cognition/*physiology; Diagnostic Imaging/methods; Humans; *Light; Melatonin/metabolism; Retina/anatomy & histology/physiology; Visual Pathways/anatomy & histology/physiology
Abstract Humans are a diurnal species usually exposed to light while engaged in cognitive tasks. Light not only guides performance on these tasks through vision but also exerts non-visual effects that are mediated in part by recently discovered retinal ganglion cells maximally sensitive to blue light. We review recent neuroimaging studies which demonstrate that the wavelength, duration and intensity of light exposure modulate brain responses to (non-visual) cognitive tasks. These responses to light are initially observed in alertness-related subcortical structures (hypothalamus, brainstem, thalamus) and limbic areas (amygdala and hippocampus), followed by modulations of activity in cortical areas, which can ultimately affect behaviour. Light emerges as an important modulator of brain function and cognition.

Title NixNox procedure to build Night Sky Brightness maps from SQM photometers observations Type Report
Year 2014 Publication E-prints Complutense Abbreviated Journal
Volume Issue 26982 Pages
Keywords Skyglow; measurement; SQM; SQM-L; mapping
Abstract The NixNox procedure to build all-sky maps of the nocturnal night sky brightness using SQM photometers is described. Astronomers belonging to amateur associations in Spain are using this observational method to obtain data of their preferred sites of observation to characterize the astronomical quality of the sky and the sources of light pollution.
