The hemispheres are not equal: How the brain is not symmetrical

Although the brain is divided into two halves, it is not exactly a mirror image. Some functions are processed more on the left side, others more on the right. Scientists have now discovered heritable underpinnings of brain asymmetry and how much we sha…

Resident physicians report COVID-19 impacts

A study assessed resident physicians’ perceptions, coping strategies and self-reported levels of depression, anxiety and stress experienced during the early phase of the pandemic.

Study links length of REM sleep to animals’ body temperature

The study suggests a previously unobserved relationship between body temperature and REM sleep, with REM sleep appearing to act like a ‘thermostatically controlled brain heater.’

Can the brain recover after boxers, MMA fighters stop fighting?

Boxers and mixed martial arts (MMA) fighters may see some recovery in their thinking and memory skills as well as brain structure after they stop fighting, according to a new study.

Brain patterns reveal why elderly drivers are prone to mistaking the gas pedal for the brake pedal

Researchers in Japan have found that older participants have longer reaction times, slower decision times, and greater brain activation in the parts of the brain involved with inhibition and switching tasks. These findings suggest insights into the cau…

A switch telling the brain when to learn and when to remember

The memory system alternates between periods of learning and remembering. These two functions are controlled by different neural circuits. Using an animal model, scientists recently identified a neural signal in the hippocampus, a brain region essentia…

This fungus shrinks in size to better infect the brain

A fungus that is a common cause of fungal meningitis undergoes a remarkable transformation once it enters the body, allowing it to infect the brain, according to new research. The discovery could lead to new strategies for blocking Cryptococcus neoform…

Mild traumatic brain injury increases risk of behavioral and emotional problems in kids

Researchers have found that kids who experience a traumatic brain injury (TBI), even a mild one, have more emotional and behavioral problems than kids who do not.

The gene to which we owe our big brain

ARHGAP11B — this complex name is given to a gene that is unique to humans and plays an essential role in the development of the neocortex. The neocortex is the part of the brain to which we owe our high mental abilities. A team of researchers has inve…

How visual information travels from the retina to the midbrain

Neuroscientists have revealed the precise connections between sensory neurons inside the retina and the superior colliculus, a structure in the midbrain. Neuropixels probes are a relatively recent development, representing the next generation of electr…
