Document Summary
Chapter 2: the brain an overview of structure and function. Maximum brain weight is 1350 grams at age 20. Hindbrain contains medulla oblongata, pons, and cerebellum. Medulla oblongata transmits info from the spinal cord to the brain, and regulates life support functions. The pons acts as a neural relay centre, facilitates the crossover of info between the left side of the body and the right side of the brain and vice versa. The cerebellum contains neurons that coordinate muscular activity, and also governs balance and involves general motor behaviour and coordination. The midbrain is involved in relaying information between other brain regions, contains reticular formation and helps keep us awake and alert and is involved in the sudden arousal we may need to respond to a threatening stimulus. The forebrain is related to cognitive issues. It consists of the thalamus, which is the switching station for sensory info and also involves memory.
