How do fruit flies see in color?

Researchers have identified a circuit in the brains of fruit flies, which enables them to see in color. The network is similar to that which allows human color vision. The findings could help in the development of AI technologies.

Why, Sometimes, We Don’t See What We Actually Saw

Crashes in visual processing occur when neurons processing one image are tasked with processing another too quickly. This results in either one or both images being unable to reach our conscious awareness.

A computer that understands how you feel

EmoNet, a new convolutional neural network, can accurately decode images into eleven distinct emotional categories. Training the AI on over 25,000 images, researchers demonstrate image content is sufficient to predict the category and valence of human emotions.

Why are we able to see moving objects against moving backgrounds?

The human brain can desensitize background motion and focus on smaller moving objects in the foreground as a result of activity in the middle temporal visual area. However, our ability to pick out smaller objects changes over time. Younger people are better at picking out foreground objects moving, while those over 65 have heightened awareness of objects moving in the background.

Study identifies our ‘inner pickpocket’

People are able to form the correct mental model of puzzles from either visual or haptic experiences alone and are able to predict haptic properties from visual ones. Findings suggest humans segment scenes into objects without explicit boundary cues by using purely statistical information.

Optical illusions reveal regular waves of brain activity enable visual feature integration

Optical illusions are helping researchers better understand attention and visual perception. Findings suggest attention operates periodically on the perceptual binding of visual information.

“Number sense” arises from the recognition of visible objects

Results from a new artificial intelligence study indicate number sense is spontaneously created by the visual system, without prior experience of counting.
