A New Theory for What’s Happening In the Brain When Something Looks Familiar

Researchers propose a new theory of what happens in the brain when we experience familiar seeming visual stimuli. The theory, dubbed sensory referenced suppression, suggests the brain understands different levels of activation expected for sensory input and corrects for it, leaving behind the signal for familiarity.

Do Neural Networks Dream Visual Illusions?

When convolutional neural networks are trained under experimental conditions, they are deceived by the brightness and color of a visual image in similar ways to the human visual system. Read More

Dog Brains Do Not Prefer Faces

fMRI study reveals dogs do not have a specific face area similar to that of primates. Dogs' brain activity showed little response to faces but increased in response to seeing another dog over a human. Read More

Optical Illusions Explained in a Fly’s Eyes

It seems that flies are as susceptible to optical illusions as humans. Turning on and off some neurons that govern motion detection in flies, researchers were able to alter the insects' perception of illusory motion. Read More

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. Read More

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. Read More

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. Read More

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. Read More
