PSYCH 1XX3 Chapter Notes - Chapter 6: Functional Magnetic Resonance Imaging, Radioactive Tracer, Wilder Penfield
Document Summary
Dorsal: refers to the back of the axis (behind neuraxis) Ventral: refers to the front of the axis (in front of neuraxis) Rostral: means towards the top of the axis (towards head) or (towards face) Caudal: means towards the bottom of the axis (closer to toe) or (towards back of head) The vast majority of information regarding the brain comes from experiments on animals, tissues or reduced preparations. Limitation is that the case studies of human lesions id that they are rarely isolated to specific structures. Problem can be overcome by studying specific brain lesions inducing animals models. The accuracy of this emerging understanding of structure and function can depend on the precision of the lesion. Another approach is to electrically stimulate an area of the brain and observe the result on. A variety of behaviors are affected by a single lesion behavior to build an anatomical map related to function.
