In the classic “Rubin’s vase” optical illusion, you can see either a vase or two faces. At any given moment, which scene you perceive depends on whether your brain is viewing the central vase shape to be the foreground or background of the picture. Now, researchers have made headway into understanding how the brain decides which side of a visual border is a foreground object and which is background.

Researchers have now found a new technique to measure and quantify neuronal tissue architecture in three dimensions and at high resolution, which enabled them to identify changes in neurons in Alzheimer’s.

Researchers have been able to document and visualize hearing loss-associated genes in the human inner ear, in a unique collaboration study between otosurgeons and geneticists.

Fixational eye movements are tiny movements of the eye that play a large role in our ability to see letters, numbers and objects at a distance. Researchers have further cemented the evidence for the important role of these tiny movements.
