Chapter 2.7 Research Methods on Brain Studies Flashcards
The methodologies of studying the brain can be divided into three parts: ___ , ____ , ____
neuroanatomical,
neurophysiological, and neuropsychological methods
This method allows us to see in detail the size and shape of neurons and their components
Neuroanatomical Techniques
This method uses electrons instead of light to magnify the
image to allows us to see features as small as a single molecule of neurochemical
Electron microscopy
This method allow us to trace the extent of features of the nervous system. For example, we can examine where cell bodies are or search for where the
neurons from a particular region of the brain project to.
Chemical Staining
It is an imaging technology in which
computers are used to enhance X-ray images to visualize the brain and other internal
structures of the living body.
Computerized Axial Tomography (CAT/CT)
It is an imaging technique that provides a
high- resolution image of activity in a living brain by recording the emission of
radioactivity from injected chemicals.
Positron Emission Tomography (PET)
It is an imaging technique that provides very
high-resolution structural images.
Magnetic Resonance Imaging (MRI)
Halstead-Reitan Neuropsychological Test Battery. It is a set of tests that tend to be
performed poorly by brain-damaged patients in relation to other patients or healthy controls; the scores on each test are added together to form a single aggregate score. It
typically begins with begin with the wechsler adult intelligence Scale (waiS).
Neuropsychological Methods
