Role of Cerebellum and Brain Stem in Construction of Human Psique. José Antonio O’Daly Carbonell


The cerebellum is involved in cognitive functions by acquiring knowledge through thought, experience, the senses, thru processes as attention, memory, judgment, evaluation, reasoning and computation, problem solving and decision making, comprehension and production of language as well as movement related functions the most solidly established. Purkinje cells are distinguished by their dendritic tree, receive 200,000 synapses, information from 200 million mossy fiber inputs then expanded to 40 billion granule cells, whose parallel fiber outputs then converge onto 15 million Purkinje cells. The medulla oblongata is responsible for the autonomous nervous system as control of ventilation, cardiovascular and vasomotor centers, controlling baroreceptors, reflex centers of vomiting, coughing, sneezing, including the pharyngeal reflex, the swallowing reflex, and the masseter reflex or bulbar reflexes. The pons contains nuclei that relay signals from the forebrain to the cerebellum, with nuclei that deal with sleep, respiration, swallowing, bladder control, hearing, equilibrium, taste, eye movement, facial expressions, facial sensation, and posture, helping brain in mind construction.
