Vision. Scientists Discover the Origin of a Giant Synapse. How do we locate the spatial position of sounds?
Scientists have revealed a mechanism responsible for the creation of giant synapses in the brain that allow us to efficiently process auditory information. Humans and most mammals can determine the spatial origin of sounds with remarkable acuity. Variation in Bitter Receptor mRNA Expression Affects Taste Perception. Do you love chomping on raw broccoli while your best friend can’t stand the healthy veggie in any form or guise?
Part of the reason may be your genes, particularly your bitter taste genes. Over the past decade, scientists at the Monell Center and elsewhere have made headway in understanding how variants of bitter taste receptor genes can help account for how people differ with regard to taste perception and food choice. However, some perplexing pieces of the puzzle remained, as two people with exactly the same genetic makeup can still differ markedly regarding how bitter certain foods and liquids taste to them. Preemies and Sound. What you hear could depend on what your hands are doing.
