Repeated DNA arrays can confer psychiatric risks
Repeated, human-specific DNA sequences are tied to an increased risk of psychiatric disorders, a Stanford study finds. It might be possible to treat the diseases with existing drugs.
Brain circuit tied to sociability
Autism spectrum disorder is marked by severe social deficits. Stanford researchers were able to reverse those types of deficits in mice by activating a single brain circuit.
New therapy for drug-resistant epilepsy
The FDA has approved the use of an implanted device that releases periodic electrical discharges in the brain to counteract seizures in people with epilepsy. In an interview, neurologist Robert Fisher described the technology and Stanford’s role in testing the device.
Impaired reward circuitry in autism
Deficits in the brain’s reward circuit are linked to social deficits in children with autism and may point the way toward better treatments, according to a new Stanford study.
Nicotine-mimicking molecules as medicine?
Stanford researchers discovered that a receptor that binds to nicotine and to clusters of beta-amyloid molecules is found on certain types of immune cells that can act as suppressors and regulators of the immune system.
Low hormone level may be autism marker
In the fluid around the brain, low levels of a hormone called vasopressin are linked to low social ability in monkeys and to autism in children, Stanford scientists have found.
Fear, courage switches found in brain
Pinpoint stimulation of a cluster of nerve cells in the brains of mice encouraged timid responses to a perceived threat, whereas stimulation of an adjacent cluster induced boldness and courage.
Brain link between obesity, depression
Reward centers in the brains of children and teenagers who are obese and depressed show abnormalities that suggest the two conditions are neurologically connected, Stanford researchers have found.
Mom’s fundraising boosts tumor research
Bereaved mother Mycah Clemons raised money for a summer scholarship at Stanford for research on diffuse intrinsic pontine glioma. The move sparked a series of experiments that have led to a possible treatment for the tumor.
Now seizure-free, Gracin gets her words back
A robotic assistant helped doctors detect seizures deep in Gracin Hahne’s brain without having to open her skull or even shave her head.
