Astrocytes are the most common type of cell in the brain and play an important role in the function of neurons -- nerve cells. New research from Sweden shows that they are also directly involved in the regulation of signaling between neurons.
Research Shows an Incentive to Snitch Produces False Information (PhysOrg) (PhysOrg.com) -- The secondary confession - also known as snitching - is widely accepted as valid evidence in criminal prosecution. Yet, the first behavioral study to investigate whether people will provide false secondary confessions has raised significant concerns about the use of such evidence when informants are offered incentives, according to University of Arkansas psychology researchers ..
Childhood Adversity May Affect Processing In The Brain's Reward Pathways Childhood adversity is associated diminished activation in the regions the brain that anticipate reward, according to a new study. Using fMRI, researchers examined the brain activity of individuals who had experienced childhood abuse that met state guidelines for maltreatment, and found weaker responses to reward-predicting cues in left hemisphere regions of the basal ganglia.
Sleep Deprivation Can Negatively Affect Information Processing A new study shows that sleep deprivation causes some people to shift from a more automatic, implicit process of information categorization (information-integration) to a more controlled, explicit process (rule-based). This use of rule-based strategies in a task in which information-integration strategies are optimal can lead to potentially devastating errors when quick and accurate categorization
Older brains make good use of 'useless' information A new study has found promising evidence that the older brain's weakened ability to filter out irrelevant information may actually give aging adults a memory advantage over their younger counterparts.
