fMRI brain scans reveal semantic tuning during both reading and listening to words are highly correlated in selective areas of the cerebral cortex. The new brain maps enabled researchers to accurately predict which words would active specific regions of the cortex.
Researchers have successfully recreated the whisker map a mouse creates of its surroundings to help it navigate the world, catch food and avoid predators.
Light sensitive cells in the fetal retina communicate as part of an interconnected network, giving the retina more light sensitivity during development that previously believed.
Using EEG to measure REM sleep allowed scientists to distinguish dreaming from wakefulness.
According to a new study, your sense of smell could be responsible for weight gain. Using mice, researchers noticed that those who lost their sense of smell also lost weight, while those mice with a super sense of smell gained more weight on a high fat diet than mice with a regular sense of smell. Findings suggest odor may play an important role in calorie burning processes; if you can't smell your food, you may burn it rather than store it.
Cell phone radiation increases the risk for a number of biological and health disorders, including gliomas and acoustic neuroma brain cancer. Researchers discuss how to reduce the risk of cell phone radiation.
Despite all of the public health warnings, many people are still ignoring instructions to socially distance during the COVID-19 pandemic. Many influential people are downplaying the severity of the virus, and convincing others that coronavirus is not as serious as health professionals would have us believe. In light of this, researchers discuss why some people stick to their beliefs and act with skepticism, despite overwhelming contradictory evidence.
Natural, restorative sleep can help stave off mental and physical decline as we age.
Diluting the blood plasma of older mice has a stronger rejuvenating effect on the brain, liver, and muscles than transplanting the blood of younger mice.
Sleep disruptions during middle age may be a potential biomarker for developing Alzheimer's disease later in life. Researchers found those who experienced sleep problems in their 40s and 50s had more amyloid beta accumulation in their brains later in life. Those whose sleep problems started in their 50s and 60s had increased levels of tau. Additionally, higher levels of tau were discovered in the brains of those who lacked synchronized brain waves associated with a good night's sleep.
