Researchers identify a driving network for compulsivity in those with alcohol use disorders. The study reports heavy drinkers have more activity in the prefronal cortex, insular and striatum, areas of the brain critical for reward and decision making.
Higher levels of the hunger hormone ghrelin predict a greater preference for smaller, immediate financial rewards over larger, delayed financial rewards.
Simulation neurons found in the amygdala allow animals to reconstruct the mental state of social partners and predict intentions. Dysfunction in these newly identified neurons may be involved in disorders associated with social behavioral problems, such as autism and social anxiety.
During decision-making tasks, activation of two brain areas in rhesus macaques mirrors the same regions as in humans. The findings shed light on the neurobiological basis of cooperation and social interactions during decision-making tasks.
Using RNA sequencing, researchers have created a spatiomolecular map of the striatum, an area of the brain implicated in decision making and addiction.
A new mathematical model evaluates the influence of social learners in group decision-making and how a critical threshold is key to informed choices.
A new study reveals the influence testosterone levels play in adolescent decision making.
A new study reports that while people on the autism spectrum often show reduced sensitivity to contextual information in perceptual tasks, this may actually head them to make more consistent choices in higher level decision making tasks.
Researchers report older people may make riskier decisions than younger people.
