PSYB57H3 Chapter 2: Structure and Function
Document Summary
Three groups in the brain: hindbrain, midbrain, and forebrain. Hindbrain: the part of the brain, containing some of the most evolutionarily primitive structures, that is responsible for transmitting information from the spinal cord to the brain, regulating life support functions, and helping to maintain balance. Medulla oblongata: a structure in the hindbrain that transmits information from the spinal cord to the brain and regulates life support functions such as respiration, blood pressure, coughing, sneezing, vomiting, and heart rate. Pons: a structure in the hindbrain that acts as a neural relay center, facilitating the crossover of information between left side of the body and the right side of the brain and vice versa. Involved in balance and in the processing of both visual and auditory information. Cerebellum: part of the brain that controls balance and muscular coordination. Brain lesions in the cerebellum cause irregular and jerky movements, tremors, and impairment of balance and of gait.
