Understanding Vision and Brain Processing

What role does the visual cortex play in the process of seeing?

• It processes raw visual information before conscious perception.

• It creates images directly without any input.

• It is responsible for hearing.

• It only receives signals from the eyes.

What was the significant finding of the University of London study in the 1960s?

• Electrodes cannot be used on the brain.

• The visual cortex cannot be stimulated.

• Phosphenes can be created by stimulating the visual cortex.

• The visual cortex is unrelated to the visual field.

What are phosphenes?

• A part of the eye.

• A type of visual illusion.

• Spots of light seen when the visual cortex is stimulated.

• A new type of camera lens.

What was the main challenge faced by researchers in creating shapes on the visual cortex?

• Difficulty in finding the visual cortex.

• Insufficient number of participants.

• Inability to isolate electrical currents in the brain.

• Lack of funding for research.

How did researchers overcome the challenge of creating shapes on the visual cortex?

• By using more electrodes.

• By tracing the outline of shapes with electrodes.

• By increasing the electrical current.

• By using a different part of the brain.

What potential application does the tracing of shapes on the visual cortex have?

• Improving color perception.

• Creating a visual prosthetic for the blind.

• Enhancing night vision.

• Developing new types of cameras.

What is the long-term goal of stimulating the visual cortex?

• To enhance memory retention.

• To develop new languages.

• To allow people to see without eyes.

• To improve hearing abilities.
