Combining Technologies to View the Retina in Unprecedented Detail
Researchers say adaptive optics enables direct imaging of neural tissue, which could lead to earlier detection of diseases that affect eye tissue.... Read More...
Brain Learns to Recognize Familiar Faces Regardless of Where They Are in Visual Field
Researchers report facial recognition varies by where they appear in the visual field, and this variability is reduces through learning familiar faces via social interactions. The study reports repeated social interactions tune visual neurons in the face processing network to enable consistent and rapid rapid recognition of familiar faces.... Read More...
Link Between What We See and How We Remember ‘Breaks’ As We Age
A new study reports older adults exhibit greater eye movements, but this does not correlate with an increase in brain activity patterns. Researchers say, while the eyes and brain are taking in environmental information, the link to creating memories of what is seen weakens over a life time.... Read More...
da Vinci’s Artistic Genius May Have Been Partly Due to Eye Condition
Researchers report the reason for da Vinci's artistic genius may be the result of an eye condition that gave him an unusual ability to recreate 3D shapes. The study reports a number of other great masters may also have suffered from the same condition.... Read More...
