ADHD Medications Focus The Brain On A Task’s Benefits

Common assumption has long held that Ritalin, Adderall, and similar drugs work by helping people focus. A new study shows that these medications — usually prescribed to individuals diagnosed with attention deficit hyperactivity disorder, but often used by otherwise healthy people as a “study aid” — actually work by directing…Continue readingADHD Medications Focus The Brain On A Task’s Benefits

The Striatum Builds Behavioral Sequences From Sub-second Components

The brain relies on an exquisite balance between the activity of two populations of neurons in a part of the brain called the striatum, the hub for motor and action planning, suggests a new study led by scientists from Harvard Medical School. The findings could help researchers better understand conditions…Continue readingThe Striatum Builds Behavioral Sequences From Sub-second Components

Psychosis Risk Linked To Impaired Probabilistic Category Learning

Boosting how well people at risk for psychosis learn from positive and negative feedback could potentially keep psychosis at bay, researchers at the University of Missouri have found. The team also found that brain scans using functional magnetic resonance imaging, coupled with behavioral measures, could provide markers for the diagnosis…Continue readingPsychosis Risk Linked To Impaired Probabilistic Category Learning

Cortico-striatal Regulation Of Striatal Activation Is Disrupted In Psychopathy

Psychopath’s brains are wired in a way that leads them to over-value immediate rewards and neglect the future consequences of potentially dangerous or immoral actions, a new study reports. The study relies on brain scans of nearly 50 prison inmates to help explain why psychopaths make poor decisions that often…Continue readingCortico-striatal Regulation Of Striatal Activation Is Disrupted In Psychopathy

Intolerance Of Uncertainty Linked To Striatum Grey Matter Volume

Individuals who have trouble coping with uncertainty or the ambiguity of possible future threats may have an unusually large striatum, an area of the brain already associated with general anxiety disorder, according to new research. Lead author Justin Kim, PhD, of Dartmouth College, said: “Uncertainty and ambiguity of potential future…Continue readingIntolerance Of Uncertainty Linked To Striatum Grey Matter Volume

What Is The Striatum?

The striatum, also known as the neostriatum or striate nucleus, is a subcortical part of the forebrain and a critical component of the reward system. It receives glutamatergic and dopaminergic inputs from different sources and serves as the primary input to the rest of the basal ganglia system. In all…Continue readingWhat Is The Striatum?

Striatum Rhesactome Regulates Amphetamine Induced Motor Activity

A specific signaling circuit in the brain is deeply involved in motor activity, scientists from the Florida campus of The Scripps Research Institute have found. The new findings that could have an impact the development of therapies for a number of currently untreatable brain disorders such as Parkinson’s and Huntington’s…Continue readingStriatum Rhesactome Regulates Amphetamine Induced Motor Activity
