Document Summary
Techniques: eeg: function, pneumoencephalogram: structure, ct: structure, pet: function, mri: structure fmri: function. Bundle of mylineated axons communicate from left to right processing information. Homotopic callosal pathways: like structures in the left and right hemispheres are directly connected. Those systems tend to be processors of complex infomation: diencephalon ( third ventricle) Develop from hid to mid to forbebrain, telecephalon, which also refer to end brain. is the last one to develop. Midbrain: mesencephalon superior colliculus is a layered, multi-sensory structure. Its upper layer receives visual signals from the retina of the eye, while the lower layers process multiple signals from various other parts of the brain. Brain size and intelligence: chihuahua has the highest brain to body size ratio, actually, the synapses are more relevant to intelligence. Disease: no cns disease, alzheimer"s disease ( see page 19) Due to the degeneration of cells in the nucleus basalis of the forebrain that use acetylcholine.
