BIOL 313 Lecture Notes - Lecture 2: Deep Cerebellar Nuclei, Olfactory Bulb, Purkinje Cell
Document Summary
Lecture 3 and 4 anatomy of the brain and nerves. Cerebral cortex higher brain function, divided into hemispheres and lobes, which are separated by specific sulci/gyri. Connected by corpus callosum, which is a massive bundle of fibers made of white matter (mylenated axons) Basal ganglion - used for planning and carrying out movement, postural adjustments. In 1953, henry moliason underwent brain surgery to cure the epileptic seizures he was experiencing. His surgeon couldn"t find the exact location where the seizures began, so he chose to cut out pieces of hm"s temporal lobe, where he removed both hippocampi. As a result hm lost all ability to form new memories. Olfactory bulb sensory neurons in nose bind to chemicals, which project themselves into the olfactory bulb to experience smell. Thalamus processes nearly all sensory and motor information going to and from the cortex. Maintain body temperature, salt balance, blood pressure. Midbrain - mesencephalon many important relay stations.
