How the Brain’s Internal States Affect Decision-Making

Animals slowly shift their likelihood of detecting stimulus changes over ten minutes. Researchers found the activity of neural populations from the V4 visual area and prefrontal cortex slowly drifted together with the behavioral fluctuations. The slow drift acts as an impulsivity signal.

Neurons can shift how they process information about motion

When it comes to processing information about motion, neurons in the ventral intraparietal area of the brain are more flexible in switching between reference frames. The findings could be used to develop neural prosthetics designed for motion control.

Our visual world of color is largely incorrect

People are oblivious to change when color is removed from peripheral vision. Research reports the brain likely fills in for much of our perceptual experience when it comes to seeing the entire picture in color.

Why visual perception is a decision process

Prediction errors play a role in the context of dynamic perceptual events that take place within fractions of a second. Findings support the hypothesis that visual perception occurs as a result of a decision process.

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.
