Rayleigh scattering causes the reddening of the sun at sunset — an example of how longer wavelengths (yellow and red compared to blue in blue sky) penetrate matter (dust at sunset) better. (credit: Wikipedia/CC) Researchers at The City College of New York (CCNY) have determined the optimal wavelengths for bioimaging of the brain at longer… Continuar lendo ‘Golden window’ wavelength range for optimal deep-brain near-infrared imaging determined
Although attention plays a ubiquitous role in perception and cognition, researchers lack a simple way to measure a person’s overall attentional abilities. Because behavioral measures are diverse and difficult to standardize, we pursued a neuromarker of an important aspect of attention, sustained attention, using functional magnetic resonance imaging. To this end, we identified functional brain… Continuar lendo A neuromarker of sustained attention from whole-brain functional connectivity
According to the World Health Organization, anxiety and depressive disorders are a leading source of disability, affecting hundreds of millions of people. Children can inherit an extremely anxious temperament, which is a prominent risk factor for the later development of anxiety, depression, and comorbid substance abuse. This study uses high-resolution functional and structural imaging in… Continuar lendo Intergenerational neural mediators of early-life anxious temperament
