Motivation depends on how the brain processes fatigue

How do we decide whether or not an activity which requires work is ‘worth the effort’? Researchers have shown that the willingness to work is not static, and depends upon the fluctuating rhythms of fatigue.

Exercise may boost kids’ vocabulary growth

Swimming a few laps likely won’t turn your child into the next Katie Ledecky or Michael Phelps, but it just might help them become the next J.K. Rowling or Stephen King. A recent study suggests aerobic exercise, such as swimming, can boost kids’ vocabu…

More than just walking: A new role for core brain region

For decades, a key brain area has been thought to merely regulate locomotion. Now, a research group has shown that the region is involved in much more than walking, as it contains distinct populations of neurons that control different body movements. T…

Scientists uncover how decisions about what we see are relayed back through the brain

Researchers have discovered that decisions based on visual information, which involve a complex stream of data flowing forward and backwards along the brain’s visual pathways, is broadcast widely to neurons in the visual system, including to those that…

Eating for hunger or pleasure? Regulating these feeding behaviors involves different brain circuits

Researchers discovered that although the brain regulates feeding for pleasure and for hunger through serotonin-producing neurons in the midbrain, each type of feeding is wired by its own independent circuit that does not influence the other type of fee…

Scientists discover early signs of frontotemporal dementia in personalized cerebral organoids

Frontotemporal dementias are a group of fatal and debilitating brain disorders for which there are no cures. Researchers describe how they were able to recreate much of the damage seen in a widely studied form of the disease by growing special types of…

Brain’s ‘memory center’ needed to recognize image sequences but not single sights

The visual cortex stores and remembers individual images, but when they are grouped into a sequence, mice can’t recognize that without guidance from the hippocampus, according to a new study.

What does a virtual roller coaster ride tell us about migraine?

When experiencing the ups and downs of a virtual roller coaster ride, people who get migraine headaches reported more dizziness and motion sickness than people who do not get migraines, according to a new study.

Neuroscientists posit that brain region is a key locus of learning

Long thought of as a generic alarm system, the locus coeruleus may actually be a sophisticated regulator of learning and behavior, according to a new review.

‘Feel good’ brain messenger can be willfully controlled, new study reveals

Researchers have discovered that spontaneous impulses of dopamine, the neurological messenger known as the brain’s ‘feel good’ chemical, occur in the brain of mice. The study found that mice can willfully manipulate these random dopamine pulses for rew…
