    Computational simulations of the biofluid flow in the ventricles in the brain are performed using computational fluid dynamics method. The head movements considered are head nodding motions. The cerebrospinal fluid flow is modeled as a Newtonian fluid with properties at the core body temperature. The motions of the brain are associated with two head motions. One is the normal nodding that is customarily signaling agreement and the second represents a hypnogogic jerk. The results of the simulations show that the cerebrospinal fluid flows in the brain ventricle are moderately affected by the light nodding, but the effects are more significant during the hypnagogic jerk motion, where mixing of the cerebrospinal fluid is distinctly enhanced. The outcomes illustrate that the head motions are significant drivers of ventricular cerebrospinal fluid flow simulated.
