Which statement is NOT true regarding the Parvocellular pathway compared to the Magnocellular pathway?

The Parvocellular pathway, also known as the P pathway, specializes in processing fine details and color information, making it essential for high-resolution visual tasks. It is indeed more attuned to higher spatial frequencies, which allows for the perception of fine details and textures in visual stimuli.

In contrast, the Magnocellular pathway, or M pathway, is more sensitive to motion and low-contrast stimuli, functioning at lower spatial frequencies but with a faster response time. It plays a crucial role in detecting movement rather than detailed color analysis.

FDT (Frequency Doubling Technology) testing primarily utilizes the Magnocellular pathway. This test assesses contrast sensitivity through low spatial frequency stimuli, which makes it effective in detecting early glaucomatous changes. Therefore, the statement that the Parvocellular pathway is primarily used in FDT testing is not true, as it is actually the Magnocellular pathway that is engaged in this type of testing.
