Document Summary
The human system axis, or neuraxis, curves as you go up towards the head. The term rostral means towards the top of the axis and caudal means towards the botom of the axis. Locaions in the brain that are more central or towards the midline of the brain are referred to as medial. Locaions in the brain that are towards the outside regions are referred to as lateral. Most invasive research in neuroscience is not done with humans, but rather, the vast majority of what is known about the nervous system comes from work with animals, issues, or more reduced preparaions. Limitaion of these case studies of human brain lesions is that they are rarely isolated to speciic structures. This problem can be overcome by studying speciic brain lesions induced in animal models. In such studies, a researcher destroys, removes or inacivates a deined brain region and observes the result on behavior.
