Since these brain areas are all interconnected, an important next step will be to determine their relative roles in the categorization process.” We are not born with a built-in ab...

After 12 days, the concentration of ultrafine particles in the olfactory bulb rose 3.5-fold and doubled in the lungs, the study found. Although the ultra-tiny particles did not cause obvious lung inflammation, severa...

The lessening of these abilities indicates the buildup of more plaques and tangles in the brain. The buildup results from abnormal protein accumulation inside...
