Search-and-rescue dogs are prized for their ability to sniff out a hiker buried in deep snow. But how exactly do their noses work?
UC Berkeley engineers have built the first dust-sized, wireless sensors that can be implanted in the body, bringing closer the day when a Fitbit-like device could monitor internal nerves, muscles or organs in real time.
Older people’s short-term memory is generally slower and less accurate compared to younger people. But a new University of California, Berkeley, study suggests that brains that continue to perform well in old age do so by rallying more of the brain to complete mental tasks.
Netflix binge-watching versus a hike in the woods. A cheeseburger versus kale salad. Fentanyl versus Tylenol. New UC Berkeley research suggests our brain activity could be influenced to make the healthier choice.
Alexander Huth, a postdoctoral researcher in neuroscience at UC Berkeley, has won a prestigious early-career award for his work in decoding semantic language in the brain.
UC Berkeley scientists have taken a step in that direction by building a “semantic atlas” that shows in vivid colors and multiple dimensions how the human brain organizes language.
UC Berkeley scientists have captured unique images of problem-solving in action by tapping into the minds of mice. The study shows rapid rewiring in the rodents’ frontal brains after they learn by trial and error.
Male friendships, portrayed and often winked at in bromance movies, could have healthful effects similar to those seen in romantic relationships, especially when dealing with stress.
New research led by scientists at UC Berkeley shows for the first time that PET scans can track the progressive stages of Alzheimer’s disease in cognitively normal adults, a key advance in the early diagnosis and staging of the neurodegenerative disorder.
A team of scientists, including a UC Berkeley pioneer in odor mapping, has received a $6.4 million grant from the National Science Foundation to dig deeper into how humans and animals navigate by using their sense of smell and converting odors into spatial information.
Like Duke Ellington’s 1931 jazz standard, the human brain improvises while its rhythm section keeps up a steady beat. But when it comes to taking on intellectually challenging tasks, groups of neurons tune in to one another for a fraction of a second and harmonize, then go back to improvising, according to new research led by UC Berkeley.
A new UC Berkeley study shows that sleep deprivation dulls our ability to accurately read facial expressions. This deficit can have serious consequences, such as not noticing that a child is sick or in pain, or that a potential mugger or violent predator is approaching.
Challenging the idea that addiction is hardwired in the brain, a new UC Berkeley study of mice suggests that even a short time spent in a stimulating learning environment can rewire the brain’s reward system and buffer it against drug dependence.
Sleep may be a missing piece of the Alzheimer’s puzzle. The toxic protein that is the hallmark of Alzheimer’s disease blocks the deepest stages of sleep, resulting in memory decline, according to new research.
Neuroscientist Linda Wilbrecht can observe “rewiring” in the living brain using an imaging instrument called a twophoton laser scanning microscope, which has a resolution better than 1/10,000 of an inch.
If early intervention is key, then so is the ability to detect even the slightest sign of neurological damage. The William Jagust Lab is using statistical and computational approaches to refine PET scan sensitivity to identify a possible Alzheimer precursor.
What if there were a pill that made you more compassionate? A new study finds that giving a drug that changes the neurochemical balance in the brain causes a greater willingness to engage in prosocial behaviors, such as ensuring that resources are divided more equally.
