Document Summary
Brain complexity of different animals th january 2016. Consumes almost 20% of entire metabolic energy. More surface area=more brain needed to process information based on body size and dot)=residual. Regression line= predicts how big your brain should be. As you go further away from line (difference between line. Brain and spinal cord: cns (inside of skull) Pns: outside of skull: cranial nerves: direct connections to brain (interconnectedness withcns, spinal nerves: nerves connect to spinal cord, autonomic system, consists of nerves and bundles of axons. Gyri and sulci: allow small brained animals to develop a greater complexity to the brain without growing larger. Evolutionary correction is gyri and sulci: more surface area in a packed brain large enough to pass through the birthing canal. Evidence that folding leads to greater intelligence. Meninges: protective outer sheath of the brain, physical protection, blood vessels in meninges, three types of meninges. When filled with cerebrospinal fluid helps to create tensions and packs everything.
