Document Summary
1/14: neurological disorders are very prominent but grossly underfunded. Broadmann areas still used today: modern neuroscience: reductionism (the brain can never be studied in its entirety because it is the most complex organ in the body) Higher levels are a more holist approach. Process, sense, communicate, and command: at first, scientists could not make thin slices of the brain, but formaldehyde changed that. After that histology was born: histology. Able to distinguish between neurons and glia. Shows the soma and the neurite: neuron theories. Neurons are in contact with one another but not continuous. Dendrites receive signals: pictures, neuron info transport axoplasmic transport from soma to axon uses kinesin slow/fast settings retrograde transport uses dynein from axon to soma, neurites=dendrites + axon, cytoskeleton. Associated with cte and alzheimer"s when improperly folded: cte. Concussions are now taken much more seriously. Increase of tau protein expression (protein build up) 1/21: neuron classification based on dendrites, myelination.
