You would expect dysfunction in the __ in Parkinson's disease.
- A.
Hippocampus
- B.
Hypothalamus
- C.
Caudate nucleus
- D.
Cerebellum
Correct Answer
C. Caudate nucleusExplanation
In Parkinson's disease, dysfunction in the caudate nucleus is expected. The caudate nucleus is a part of the basal ganglia, which plays a crucial role in movement control. Parkinson's disease is characterized by the degeneration of dopamine-producing cells in the substantia nigra, leading to a dopamine deficiency in the caudate nucleus. This dopamine deficiency results in the motor symptoms associated with Parkinson's disease, such as tremors, rigidity, and bradykinesia. Dysfunction in other brain regions, such as the hippocampus, hypothalamus, or cerebellum, is not typically associated with Parkinson's disease.Rate this question:

Which area of the brain is relatively spared in individuals with chronic alcohol abuse?
- A.
Subcortical
- B.
Temporal
- C.
Frontal
- D.
Right hemisphere
Correct Answer
B. TemporalExplanation
Individuals with chronic alcohol abuse often experience significant damage to the brain, particularly in the frontal and subcortical regions. However, the temporal lobe is relatively spared from the effects of alcohol abuse. This may be due to the fact that the temporal lobe is less vulnerable to the toxic effects of alcohol compared to other brain regions. The sparing of the temporal lobe may help to explain why individuals with chronic alcohol abuse can still have intact memory and language functions, which are primarily controlled by this area of the brain.Rate this question:

Which of the following would be considered abnormal in an 18-month-old child?
- A.
Walking independenly
- B.
Moro response present
- C.
Moro response absent
- D.
6-20 word vocabulary
Correct Answer
B. Moro response presentExplanation
The Moro response is a primitive reflex that is typically present in newborns and gradually disappears by the age of 6 months. Therefore, if the Moro response is still present in an 18-month-old child, it would be considered abnormal. This reflex involves the baby's arms extending outwards and then bringing them back in when they feel a sudden change in their position or a loud noise. Its persistence beyond the expected age range could indicate a neurological or developmental issue.Rate this question:

A GCS score of 4 (at the scene of an accident would be indicative of a ___ injury.
- A.
Mild
- B.
Moderate
- C.
Severe
- D.
Prfound
Correct Answer
C. SevereExplanation
A GCS score of 4 indicates a severe injury. The Glasgow Coma Scale (GCS) is used to assess a person's level of consciousness after a head injury or trauma. It evaluates eye opening, verbal response, and motor response. A score of 4 suggests that the person is in a deep state of unconsciousness and is unable to open their eyes, make any verbal response, or exhibit any purposeful movement. This level of impairment signifies a severe injury that requires immediate medical attention.Rate this question:

____ is when the post synaptic cell develops a heightened sensitivity to a neurotransmitter following a brain injury.
- A.
Regeneration
- B.
Sprouting
- C.
Denervation supersensitivity
- D.
Dishinibition of compensatory zone
Correct Answer
C. Denervation supersensitivityExplanation
Denervation supersensitivity is when the post synaptic cell becomes more sensitive to a neurotransmitter after a brain injury. This heightened sensitivity occurs because the nerve fibers that normally release the neurotransmitter are damaged or lost, leading to an increased responsiveness of the remaining receptors on the post synaptic cell. This phenomenon can result in abnormal neuronal activity and potentially contribute to the development of neurological symptoms following a brain injury.Rate this question:

Which of the following is NOT a common neuropathological finding in Autism?
- A.
Cerebellar atrophy
- B.
Low activitation of fronto-parietal regions
- C.
Increased ventricular size
- D.
Reduced brainstem activity
Correct Answer
D. Reduced brainstem activityExplanation
Reduced brainstem activity is not a common neuropathological finding in Autism. Autism is typically associated with abnormalities in brain structure and function, including increased ventricular size, low activation of fronto-parietal regions, and cerebellar atrophy. However, reduced brainstem activity is not commonly observed in individuals with Autism.Rate this question:

Holopronsencephaly is likely a result of a deviation in which stage of enbryogeneis
- A.
Ventral induction
- B.
Secondary neurolation
- C.
Organization
- D.
Migration
Correct Answer
A. Ventral inductionExplanation
Holoprosencephaly is a developmental disorder characterized by incomplete separation of the forebrain during embryogenesis. Ventral induction refers to the process by which the ventral (bottom) structures of the brain are formed. Therefore, a deviation in ventral induction could lead to abnormalities in the development of the brain, potentially resulting in holoprosencephaly. This suggests that ventral induction is the stage of embryogenesis that is likely affected in individuals with holoprosencephaly.Rate this question:
