Document Summary
Neuropsychology: the scientific study of the relations between brain function a behavior. Brain theory: the brain is the source of behavior. Neuron theory: unit of brain structure and function is the neuron or nerve cell. Brain is the tissue found within the skull (cranium) Cerebrospindal fluid (csf) cushions the brain and assists in removing metabolic waste. The cerebral cortex, cortex meaning bark because the cortex"s folded appearance resembles the bark of a tree and cortical tissue covers most of the rest of the brain. Fold or bumps in the cortex are called gyri (gyrus is greek for circle), and the creases between them are called sulci (sulcus is greek for trench) Large sucli are called fissures: the longitudinal fissure divides the two hemispheres and the lateral fissure divides each hemisphere into halves. Pathways called commissures, the largest of which is the corpus callosum, connect the brain"s hemispheres.
