Electrical impulses and chemical activities in human brain generate brain waves at frequency domains ranging between 0.5 Hz and 100 Hz that characterize different mental states. The states of attention and focus can be traced to areas within the prefrontal cortex (PFC) of the brain at gamma brainwave frequencies of about 40 Hz and above. The cerebral brain cells can be synchronized to a desired ... [Show full abstract]Read more
“Mini-brains,” or brain organoids, the latest development in stem cell technology, are organized 3D cell structures made up of different brain cells, which resemble the complexity of the human brain. Human stem cells can be grown into brain organoids in 40 days, offering neuroscientists an unprecedented opportunity to more accurately model human brain development and disease. Until now, scientists had two choices: to study the brains of other mammals and extrapolate similarities with the human brain, or study the cells that make up the brain in a dish, which although informative, can only tell us so much about how the human brain works as a whole.
The benefits of aerobic exercise — like running, dancing, spinning, and in-line roller-skating — include an increased heart rate. When your heart rate is accelerated, your body releases endorphins, natural opiates that make you feel good with no side effects. High-energy activities help you feel better physically and mentally. Just be sure to check with your doctor before starting any high-intensity workouts.
