Eyes: Your eyes scan the text on the page, processing the words and forming images in your mind. This involves complex neurological processes within the eyes and the visual cortex of the brain. Brain: Your brain decodes the visual information received from your eyes, interpreting the words, sentences, and paragraphs. It also engages in higher-level cognitive functions such as comprehension, analysis, and memory recall. Different parts of the brain are involved, including the visual cortex, language centers, and areas responsible for memory and reasoning. Hands: Your hands hold the book, turning the pages, and may even underline or annotate the text. This involves fine motor skills and coordination.
