Document Summary
Brain lesioning- abnormal disruption of the brain resulting from injury or disease (lesion is a small hole); leasioning is no limited to animal studies (mice and humans when performing a case study) Brain stimulation- inserting small electrodes to deliver stimulation. Static images (structural imaging)- good pictures to find tumors: x-ray: two- dimensional images, ct or cat scan: three-dimensional images, mri: brain structure. Dynamic images (functional imaging)- shows function of the brain: pet scan: metabolic changes, f mri: brain function. Pet scan and f mri = very slow (measures blood flow to the active cells) and. Eeg = put a net over head and measure all brain activity/electrical activity (fast, precise) Hindbrain- adjacent to top part of spinal cord. Bci- ability of brain to generate certain responses that can be harnessed by computers to be interpreted by those computers.
