What is a PET scan?

Back

A PET scan (Positron Emission Tomography) is a neuroimaging technique that provides information about brain function by detecting radioactive tracers in the brain.

Front

Which neuroimaging method monitors electrical activity in the brain?

Back

EEG (Electroencephalography) is the method that helps provide information about brain function by monitoring electrical activity.

Front

What does accommodation refer to in vision?

Back

Accommodation is the process by which the lens changes shape to focus images on the retina.

Front

What is the correct order of structures through which light passes after entering the eye?

Front

What is the role of the lens in the eye?

Back

The lens changes shape to help focus light onto the retina for clear vision.

Front

What is the function of the retina?

Back

The retina converts light into neural signals and sends them to the brain for visual recognition.

Front

What is the difference between CT and MRI scans?

Back

CT (Computed Tomography) uses X-rays to create images of the body, while MRI (Magnetic Resonance Imaging) uses magnetic fields and radio waves to produce detailed images of organs and tissues.

Front

What does the optic nerve do?

Back

The optic nerve transmits visual information from the retina to the brain.
