Our brain can recognize familiar music within just 100-300 milliseconds (0.1-0.3 of a second), according to a new study published in the journal Scientific Reports. Jagiello et al used electroencephalography and pupillometry to reveal the temporal signatures of the brain processes that allow differentiation between a familiar, well liked, and unfamiliar piece of music.

The normal form of amyloid beta has been tagged with a yellow marker in these cells, making healthy cells a uniform pale yellow (left). Contact with prion forms of amyloid beta -- for example in extracts from human brain tissue -- forces these yellow proteins into the sticky prion form as well, leading to the formation of bright yellow clumps (right).

Overview of observed standardized regression coefficients (b values) for the associations between total body fat and fractional anisotropy (FA)- and mean diffusivity (MD)-based DTI tracts for men and women. Standardized regression coefficients reflect the standard deviation (SD) change in FA and MD, respectively, per standard deviation (6.5% in women and 5.5% in men) change in total body fat. Results were adjusted for age, ethnicity, Townsend deprivation index, assessment center (baseline visit and imaging visit), smoking, alcohol use, diabetes, cardiovascular disease, and intracranial volume.
