Novel technology allows researchers to understand how a fruit fly's brain processes color.
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.
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.
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.
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.
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.
Visually represented information is a functional part of conceptual knowledge. The extend of the visual representations is influenced by visual experience.
Study provides new evidence supporting the theory that perceptual limitations are caused by a correlated noise in neural activity.
Understanding how the brain decides what it should pay attention to is key to understanding how prediction plays a tole in autism.
Reward does not improve visual perception learning unless it is followed by a good night's sleep.
