👉 The handed fluid refers to a type of fluid found in the central nervous system, particularly in the brain, that exhibits handedness or chirality. This means that the fluid has a preference for interacting with one-handed or right-handed molecules, similar to how left-handed people often exhibit a preference for certain handedness in various activities. In the brain, this handedness is thought to be linked to the asymmetry in the structure and function of neurons and neural pathways, which can lead to differences in cognitive processes, language abilities, and other neurological functions between left-handed and right-handed individuals. This phenomenon is a key aspect of understanding handedness in neurobiology.
