3 Big Things We Learned About the Brain in 2019

In 2019, three major brain discoveries were made. First, humans may sense Earth's magnetic field, as shown by changes in alpha waves during a controlled experiment. Second, some people can smell without olfactory bulbs, suggesting brain adaptability or undetected structures. Lastly, during sleep, cerebral spinal fluid flows in waves, potentially flushing out toxins and aiding brain health. These findings highlight the brain's complexity and adaptability.
