Researchers report the same subset of neurons encode actual and illusory flow motion, supporting the concept Jan Purkinje proposed 150 years ago, that "illusions contain visual truth".
A new study challenges 75 year old dogma of mammalian vision. Researchers have shows the post rhinal cortex obtains visual data from the superior colliculus and is not dependent upon information from primary visual cortex.
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.
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.
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.
Using human retinal tissue grown from stem cells, researchers shed light on how color vision develops. The study found thyroid hormones dictated whether the cells became blue, green or red photoreceptors.
