Define human neuropsychology. Ans✓✓-the scientific study of the relationship
between behavior, cognition, and the brain in humans
Name the four goals of a neuropsychological assessment. Ans✓✓-1. Determine a
person's general level of cerebral functioning, identify cerebral dysfunction, and
localize any injuries in the brain
2. Document the recovery of functioning after brain injury
3. Facilitate patient care and rehabilitation
4. Identify unusual brain organization
What are the two theoretical frameworks underlying neuropsychology? Ans✓✓-
1. The Brain Hypothesis— the brain is the source of behavior
2. The Neuron Hypothesis— the neuron is the unit of brain structure and function
What are the three main divisions of the brain? Ans✓✓-1. Forebrain (cerebrum)
— divided into two symmetrical halves: left hemisphere & right hemisphere
2. Brainstem— responsible for unconscious behavior
3. Cerebellum (little brain)— takes care of skilled movements
Distinguish between sulci and gyri in the cerebral cortex. Ans✓✓-Gyri are folds or
bumps in the cortex (gyrus = Greek for "circle"), whereas sulci are the creases
between them (sulcus = Greek for "trench")
, What is the correct order of the meninges from top to bottom? Ans✓✓-dura
mater, arachnoid, pia mater
Where is cerebrospinal fluid found? Ans✓✓-Cerebrospinal fluid is found is the
subarachnoid space, which lies between the Arachnoid Space and the Pia Mater.
CSF also circulates throughout the brain's four ventricles, as well as the spinal
column.
What does it mean to say that the cortex is "crossed?" Ans✓✓-The cortex is
considered "crossed" in that the left hemisphere controls the right hand, leg, and
right part of the face, and the right hemisphere controls the left hand, leg, and left
part of the face
What are the three basic types of neurons and what are their functions? Ans✓✓-
1. Sensory Neurons— takes sensory information into the central nervous system
(comprised of bipolar neurons or somatosensory neurons)
2. Interneurons— connect sensory and motor activity in the central nervous
system (include stellate, pyramidal, and Purkinje cells)
3. Motor Neurons— send signals from the brain and spinal cord to the muscles; all
behavior/movement is produced through the motor neurons
What are the five types of glial cells and what are their functions? Ans✓✓-1.
Ependymal Cells— line the ventricles within the brain and make cerebrospinal
fluid
2. Astroglia— star-shaped; provide both nutrients and structural support to
neurons
3. Microglia— tiny glia; fight infections and remove debris
4. Oligodendroglia— glia w/ few branches; insulate neurons in the central nervous
system
