For many years, delineating such modules in the human brain was based on following patients with a specific neurological dysfunction and then localizing the corresponding anatomical defect via brain autopsy. The most dramatic discovery of this type is due to Pierre Paul Broca, who proclaimed in ...
"If you go into the data on gene expression or brain structure at different ages, you see these lifespan patterns that we don't know what to make of. The brain seems to continue to change in dynamic ways through early adulthood and middle age," Germine says. "The question is: What d...
Under an alternative account, salience processing may still be generally impaired in psychosis, but this may be secondary to dysfunction of diverse neural systems. In the current study, we, therefore, investigated brain responses in the SN/VTA and other target areas to four types of salience25—...
Deep brain stimulation (DBS) of the nucleus accumbens (NAc) has proven to be an effective treatment for therapy refractory obsessive–compulsive disorder. Clinical observations show that anxiety symptoms decrease rapidly following DBS. As in clinical studies different regions are targeted, it is of pr...

Information about others’ experiences can strongly influence our own feelings and decisions. But how does such social information affect the neural generation of affective experience, and are the brain mechanisms involved distinct from those that mediat
Whenever we learn a new skill, your brain must decide where to store that skill. Many skills span multiple regions of the brain, but within those regions, they still get assigned to specific areas. The brain will of course make these assignments on its own, but can you always trust that...
In a major study, investigators have compared how individuals with Parkinson's disease respond to deep brain stimulation (DBS) at two different sites in the brain. Contrary to current belief, patients who received DBS at either site in the brain experien
Stimulant medication is approved to treat the three types of ADHD in adults as well as children age six or older. Stimulants work by increasing the amount of dopamine and norepinephrine in certain parts of the brain that can increase focus, improve working memory, and direct impulse c...
An essential role would be played by creation of a data registry for patient characteristics and outcomes, as suggested by investigators in the field and by NIMH. Disclosure: B.D. Greenberg: Part 1; Medtronic, Inc.; Jazz Pharmaceu- ticals. Part 3; Medtronic, Inc. Deep Brain Stimulation ...
