Previous brain-wide association studies (BWAS) have linked specific environmental and behavioral variables to brain variability. In this work, we mapped 649 variables to children’s brains and compared...

ADHD, sleep deprivation, amphetamines and the truth of why they work

The substantia nigra and all Parkinson’s disease deep-brain stimulation targets are selectively connected to the somato-cognitive action network rather than to effector-specific motor regions.

A brain network first identified by Washington University in St. Louis School of Medicine researchers, called SCAN, is shown in a new study to be the neurological basis for Parkinson’s disease. Patients receiving treatments targeted to this brain region, rather than to surrounding areas, experienced greater improvements in symptoms.

A new study suggests Parkinson’s may stem from disruptions in a little-known brain network, reshaping how doctors think about the disease.

The substantia nigra and all Parkinson’s disease deep-brain stimulation targets are selectively connected to the somato-cognitive action network rather than to effector-specific motor regions.

Modafinil is a non-amphetamine central nervous system stimulant with wakefulness-promoting properties. It is used in the treatment of conditions which cause excessive daytime sleepiness. In the United...

New research suggests that prescription stimulants for ADHD don't actually improve attention directly. They work on different pathways in the brain that support attention. .

Functional MRI studies across ages show that the classic homunculus of the motor cortex in humans is in fact discontinuous, alternating with action control-linked regions termed the somato-cognitive ...
