What is the mechanism of black and white checkerboard stimulation?

Black and white chessboard stimulation is a kind of visual stimulation, and its mechanism mainly includes retina, visual nerve pathway and cerebral cortex.

1. retina: black-and-white chessboard stimulation can stimulate the photoreceptors of retinal photoreceptor cells, producing signals of light and dark changes.

2. Visual nerve pathway: black-and-white chessboard stimulation activates black-and-white cells in the visual nerve pathway, which are highly sensitive to black-and-white contrast and can better identify the light and dark changes in the black-and-white chessboard.

3. Cerebral cortex: It is the area responsible for processing and interpreting visual information. Black-and-white chessboard stimulation can activate many visual areas of cerebral cortex, and the activation of these areas can help the brain to better process and interpret the information in black-and-white chessboard.
