Study explores neurocognitive basis of bias against people who look different
Study explores neurocognitive basis of bias against people who look different
Research from Penn Medicine shows brain responses and attitudes reinforce the “anomalous is bad” stereotype.
How to foster supported decision making for adults with cognitive impairment
How to foster supported decision making for adults with cognitive impairment
Supported decision making helps medical professionals identify what people living with dementia can do, not what they can’t.
Risk-taking behavior has a signature in the brain, big data shows
Risk-taking behavior has a signature in the brain, big data shows
While there is no such thing as a single “risk area” of the brain, a study of 12,000 people led by the Wharton School’s Gideon Nave found a connection between genes, lower levels of gray matter, and risky behavior.
Parkinson's disease pathology is tied to the activity of cell's 'recycling centers'
Parkinson's disease pathology is tied to the activity of cell's 'recycling centers'
Genetic variations associated with both increases and reductions in risk of the neurodegenerative disease alter the action of ion channels within cellular organelles called lysosomes, a new Penn study finds.

Most people break New Year’s resolutions within a few weeks. Neuroscientist Vera Ludwig offers six tips to move mindfully through this process, leading to a greater chance for success.
Organoids to rebuild the brain
Organoids to rebuild the brain
Penn neuroscientists are developing innovative ways to treat neurological diseases, including implanting neural tissue like a brain organoid to rebuild brain circuitry.
Scientists identify brain cells that drive wakefulness and resist general anesthetics
Scientists identify brain cells that drive wakefulness and resist general anesthetics
A new study that identifies the neurons that promote wakefulness supports a long-debated hypothesis that the brain’s sleep regulation mechanism also regulates its response to general anesthetics.
A modified game of ‘chicken’ reveals what happens in the brain during decision-making
A modified game of ‘chicken’ reveals what happens in the brain during decision-making
Research from the Platt Labs found that in rhesus macaques, two regions of the brain mirror those of similar regions in humans, broadening the understanding of what unfolds, neurologically, when people interact and cooperate.
One step closer to a clinical fix for the side effects of monovision
One step closer to a clinical fix for the side effects of monovision
Monovision counters the deterioration of the ability to see up close but also causes dramatic visual distortions. New research confirms that a solution that successfully works with trial lenses—the special lenses used by eye doctors—also succeeds with contact lenses.

Scientists identify the region of the brain associated with risk-taking—and it could explain why some people are more likely to smoke and drink
Gideon Nave of the Wharton School spoke about research he co-authored, which identified areas of the brain linked with risk-taking. “We find that we don’t have only one brain region that is the ‘risk area,’” he said. “There are a lot of regions involved.”

Elon Musk to show off working brain-hacking device
Ari Benjamin, a doctoral student in the School of Engineering and Applied Science, said the biggest stumbling block for brain-to-machine interface technology is the complexity of the human brain. "Once they have the recordings, Neuralink will need to decode them and will someday hit the barrier that is our lack of basic understanding of how the brain works, no matter how many neurons they record from,” he said. "Decoding goals and movement plans is hard when you don't understand the neural code in which those things are communicated."

A radical new model of the brain illuminates its wiring
Danielle Bassett of the School of Engineering and Applied Science spoke about how neuroscience has led to a greater understanding of the brain’s networks and how to treat a variety of conditions. “Hopefully, with an understanding of the individual differences in the brain, we will have a better lever on how to predict human responses to a particular intervention,” she says, “and then not have to have people go for a year through different kinds of medication before we find one that works for them.”

Antarctic study shows isolation, monotony may change the human brain
Alexander Stahn of the Perelman School of Medicine led a study that found a volume decrease in the hippocampi of explorers who spent 14 months at a research station in Antarctica. “It was an average of about 7%, which is really big in terms of brain changes,” he said.
