PSYB65H3 Chapter Notes - Chapter 3: Squid, Paramagnetism, Visual Cortex
Document Summary
Limitations: differences between humans and nonhuman models. Difference in the complexity of the cns: some topics may not be suitable. Cognitive testing: detailed examination of higher cognitive functions. Begins with a personal interview that is followed by a series of tests: standardized cognitive tests, some tests may have problems with generalization beyond the sample with which they were developed. The more dense the material, the less penetrable the substance is to x-rays: makes x-rays useful for medical imaging. Painless, takes relatively little time and can be performed on an unconscious individual. Sagittal plane has images that are also perpendicular to the horizon, but they are taken along the dorsal- ventral axis. Ct scans are useful for both research and clinical applications: for clinical purposes, they help to identify anatomical abnormalities or acquired injuries. Provided that these changes are reflected in changes in tissue density. Combination of these two types of information allows the construction of 3d images of the brain.
