Marijuana: Differential effects on right and left hemisphere functions in manMarijuana, smoked at moderate doses, produced a differential impairment of the reaction times of right-handed males to pictorial stimuli presented to the left and right cerebral hemispheres. After smoking marijuana responses to...
While no one is really left-brained or right-brained only unless a hemisphere is damaged or removed, it is quite interesting to see how people test. Broad generalizations are made in popular psychology about certain functions on one side or the other. The brain receives messages through the fi...
The largest part of the brain is called the cerebrum and it is symmetrically divided down the middle into the left and right hemispheres. Each hemisphere has its own cognitive functions and while it is true that one side may be more dominant than the other, they still work together and this...
How the Left and Right Hemispheres Work Together Both sides of the brain collaborate to handle major functions such as language processing and vision. But they are also, to a degree, specialized. Some areas of the brain are more active than others during particular tasks, and one hemisphere ma...
The right-hemisphere damaged subjects demonstrated greater affective non-verbal impairment than those with left-hemisphere damage and normals, but the differences between right-hemisphere damaged subjects and left-hemisphere damaged subjects on affective mean rank scores were small. Lesion location either ...
To investigate the role of the right hemisphere (RH) in semantic control, we compared nine RH stroke patients with 21 left-hemisphere SA patients, 11 mild SA cases and 12 healthy, aged-matched controls on semantic and executive tasks, plus experimental tasks that manipulated semantic control in...
row of Fig.3). We tested for hemispheric differences in the global gradient value by averaging all gradient values across the 17 Yeo networks within each hemisphere separately for each participant in the sample and comparing these means using a pairedttest (left hemisphere vs right hemisphere)....
Intriguingly, in 90 percent to 95 percent of right-handers, the left hemisphere is dominant for language and speech functions, suggesting evolution has honed one side to handle skillful work. "If I have one part of my brain controlling my fine motor movements, it would make sense to have ...
Source analysis was used to isolate the N250m response in the left and right hemisphere. In children with language impairment left-hemisphere N250m responses were enhanced compared to those of controls, while no group difference was found in the right hemisphere. Consequently, language impaired ...
Chances are, you've heard the label of being a "right-brained" or "left-brained"thinker. Logical, detail-oriented and analytical? That's left-brained behavior. Creative, thoughtful and subjective? Yourbrain's right side functions stronger —or so long-held assumptions suggest. ...
