1. Where is grey matter located in the central nervous system?
Cerebellum, cerebrum, brain stem, and the butterfly-shaped portion of the
central spinal cord.
Rationale: Grey matter consists predominantly of neuronal cell bodies, neuropil
(dendrites and unmyelinated axons), glial cells, and capillaries. It forms the outer
1
,cortex of the cerebrum and cerebellum, exists as deep nuclei within the brainstem,
and constitutes the inner H-shaped (or butterfly-shaped) core of the spinal cord
where synaptic integration takes place.
2. What is grey matter associated with?
Learning.
Rationale: Grey matter contains the dense concentrations of synapses, dendrites,
and neuronal cell bodies responsible for processing information. Neuroplastic
structural adjustments within grey matter—such as dendritic branching and
synaptogenesis—directly underlie cognitive processing, memory consolidation,
and learning.
3. Which functions are controlled by the Frontal Lobe?
Movement, intelligence, abstract thinking, the ability to organize, personality,
behavior, and emotional control.
Rationale: The frontal lobe houses the primary motor cortex (controlling voluntary
movement) and the prefrontal cortex. The prefrontal cortex is the seat of executive
functioning, which governs higher-order cognitive capabilities including abstract
reasoning, future planning, working memory, personality expression, and the top-
down regulation of emotions and social behavior.
4. What are the primary functions of the hippocampus?
Regulates memory (specifically long-term) and anxiety.
Rationale: Located within the medial temporal lobe, the hippocampus is a core
component of the limbic system. It is absolutely essential for structural
consolidation—converting short-term memory into long-term storage—and plays a
key regulatory role in emotional processing and anxiety via its extensive reciprocal
connections with the amygdala and the HPA axis.
5. A patient recovering from a stroke has trouble with speech comprehension
and works with a speech therapist twice a week. Which part of the patient's
brain has been affected by the stroke?
The Wernicke's area.
Rationale: Wernicke's area is located in the posterior superior temporal gyrus of
2
, the dominant hemisphere (typically the left). It is the specialized cortical region
responsible for processing acoustic signals into meaningful linguistic concepts.
Damage to this area results in fluent or Wernicke's aphasia, characterized by
impaired language comprehension while verbal output remains fluent but often
nonsensical (word salad).
6. What is the primary function of Broca's area?
Speech production.
Rationale: Located in the inferior frontal gyrus of the dominant hemisphere,
Broca's area sits adjacent to the motor cortex areas controlling the face and tongue.
It is responsible for programming and executing the motor sequences necessary to
formulate speech. Damage results in expressive or non-fluent aphasia, where
comprehension is largely preserved but language production is halting and
effortful.
7. What is the role of the basal ganglia?
Involved in voluntary motor movements, cognition, and emotion.
Rationale: The basal ganglia comprise a collection of subcortical nuclei (including
the striatum, globus pallidus, substantia nigra, and subthalamic nucleus) that form
complex loops with the cerebral cortex. They act as a central motor filter,
modulating the initiation and smoothness of voluntary movements while also
contributing significantly to procedural learning, executive cognitive functions,
and emotional habit formation.
8. What is the limbic system associated with?
Emotions and learning.
Rationale: Often referred to as the "emotional brain," the limbic system includes
structures such as the amygdala, hippocampus, thalamus, hypothalamus, and
cingulate gyrus. It links higher cognitive functions of the cerebral cortex with
primitive autonomic and endocrine responses, driving survival instincts, memory
formation, spatial navigation, and basic emotional states like fear, pleasure, and
anger.
