Study: Strength of brain connectivity varies with fitness level in older adults A new study shows that age-related differences in brain health – specifically the strength of connections between different regions of the brain – vary with fitness level in older adults. The findings suggest that greater cardiorespiratory fitness – a measure of aerobic endurance – relates to stronger brain connections and likely improves long-term brain function [...]
Adults over 30 not as happy as they used to be — but teens and young adults happier than ever Are you less happy than your parents were at the same age? It may not be all in your head. Researchers led by San Diego State University professor Jean M. Twenge found adults over age 30 are not as happy as they used to be, but teens and young adults are happier than ever. Researchers [...]
Resilience-based interventions could curb depression in LGBT youths Previous research has found lesbian, gay, bisexual and transgender youths are four times more likely to commit suicide compared to their straight peers. Members of this community usually are more stressed and depressed than the general population. Now, researchers at the University of Missouri School of Medicine are exploring the role resilience plays in off-setting [...]
How do our brains reconstruct the visual world? Given that we see the world through two small, flat retinae at the backs of our eyes, it seems remarkable that what each of us perceives is a seamless, three-dimensional visual world. The retinae respond to various wavelengths of light from the world around us. But that’s just the first part of the process. Our [...]

Brain imaging reveals possible depression signature in traumatic brain injury Individuals with depression in addition to traumatic brain injury (TBI) are prone to poorer recovery, reductions in cognitive performance, greater functional disability, increased suicide attempts and other social and sexual difficulties. Since depression symptoms vary greatly, teasing apart a diagnosis in the context TBI is often difficult. However, researchers have identified a potential brain-based biomarker for depressive symptoms that could simplify the process.
Schizophrenia’s Genetic Makeup is Super Complicated New research into the genetic makeup of schizophrenia has confirmed what many researchers have long suspected — the genetics of schizophrenia is super complicated. In order to better understand diseases like schizophrenia, researchers developed a new algorithm to better map its genetic architecture. The new … ...
Scientists find neural match for complexity of visual world The complexity of the neural activity we use to process visual images reflects the intricacy of those images, a team of scientists has found. Their study offers new insights into how our brain extracts information about our natural surroundings from the light captured by our eyes.
Strength of brain connectivity varies with fitness level in older adults A new study shows that age-related differences in brain health -- specifically the strength of connections between different regions of the brain -- vary with fitness level in older adults.
