Mock Exam Questions Flashcards
What is NOT true about Pain perception:
1. The Placebo effect can be blocked by opioid antagonists
2. Top Down Modulation of Pain refers to the exclusively intracortical mechanism of pain
modulation
3. A-delta and C-fibers ascend contralateral
4. Fast pain fibers aren’t really that fast
2
Which statement about top-down pain modulation is correct?
1. Patients have to be tricked into believing in a placebo substance for it to work.
2. A major node of top-down pain modulation is the cerebellum.
3. Top-down pain modulation ensures that comparable nociceptive stimuli are subjectively perceived as being equal.
4. Top-down pain modulated relies on endogenous opioids and can be diminished or abolished by opioid antagonists.
4
What is true about interneurons, they…?
1. are known for they long axons, connecting different brain parts
2. originate in the medial and caudal ganglionic eminences
3. start to migrate as neuroblast in the ventricular zone
4. make up 30-40% of the total neuron population
2
Which statement about interneurons is false?
1. Some interneurons are excitatory.
2. Interneurons can be classified as belonging to one of three mayor subtypes (parvalbumin-posititve, PV+; somatostatin-positive, SST+; serotonin-receptor expressing, 5HTR3s)
3. Interneurons are produced within the ganglionic eminences and migrate towards the nascent cortex.
4. 30-40 % of interneurons originally produced will undergo programmed cell death (apoptosis) during development.
1
Which statement is NOT true about the Pre-Motor Areas?
1. They integrate information about circumstances and intention
2. Some Neurons in the SMA project directly to muscle fibers
3. they are part of the frontal cortex
4. They fire at cue perception in conditioned tasks
2
What does BCI do?
1. BCI measures CNS activity and converts it into device command.
2. BCI improves natural CNS output.
3. BCI skips the corticospinal track and mimics CNS.
4. All above
4
Which statement about the lower (second) motor neuron is correct?
1. Lower motor neurons are localized in the dorsal (back) part of the spinal cord.
2. Lower motor neurons are used as a common source for brain-computer interface (BCI) signal acquisition.
3. There is a horizontal topography within spinal cord segments, with medial lower motor neurons innervating proximal muscles and lateral lower motor neurons innervating distal muscles.
4. Approximately 5 % of all lower motor neurons are so-called giant Betz Cells.
3
What is the difference in the performance of emotion recognition tasks during the menstrual cycle, the accuracy is… ?
1. lower during the follicular phase, especially for sad faces.
2. lower during the follicular phase, but responses elicit faster
3. higher during the follicular phase, compared to responses in the luteal phase.
4. highest during the ovulation phase.
3
Which statement about neuroimaging findings in correlation to the menstrual cycle is correct?
1. The volume of the amygdala increases significantly just prior to ovulation.
2. Hippocampal gray matter volume has been found to increase in the late follicular phase of the menstrual cycle.
3. Reactivity of the anterior cingulate cortex (ACC) to emotional stimuli was reduced during the luteal phase.
4. Activity in areas associated with executive functions, e.g., middle and superior frontal gyri, is unaffected by the menstrual cycle
2
Which of the following structures is/are of particular importance for the production of saccadic eye movements?
1. Superior colliculi
2. Anterior thalamus
3. Orbitofrontal cortex
4. Nucleus basalis Meynert
1
Activities in which of the following is necessary for a saccade to the right?
1. right rostral interstitial nucleus
2. left medial rectus
3. right trochlear nucleus
4. all the above
2
Which statement about anti-β-amyloid (anti-Aβ) treatment in Alzheimer disease is false?
1. Immunization can be either active or passive.
2. Clinical trials in humans have, so far, yielded mixed results.
3. Aducamab animal trials have shown a reduction in Aβ-plaque levels.
4. The majority of immunotherapy trials utilize polyclonal antibodies.
4
What is the Aducanumab’s hypothesised mechanism of action?
1. Vaccination with Aducanumab elicits production of anti-Aβ antibodies.
2. Aducanumab prevents the formation of ARIA-E and ARIA-H.
3. Aducanumab binds to Aβ-oligomers and stimulates microglia to clear Aβ-plaques.
4. Aducanumab is a gene therapy treatment that substitutes APOE-ε4 with APOE-ε2.
3
Why does the consumption of SCFA (Short Term Fatty Acids) lead to an increase of cognitive functions and learning, because they ?
1. promote the permeability of the BBB (Blood Brain Barrier)
2. elevate the expression of BDNF and NMDA receptors
3. activate the proliferation of Microglia
4. promote the intestinal functions via the HPA (Hypothalamus-Pituitary-Adrenal axis).
2
Which glia cell was reported to be particularly susceptible to experimental changes of the gut microbiota, e.g., showed lack of maturation and responsiveness in germ-free (GF) mice?
1. Microglia
2. Astrocytes
3. Oligodendrocytes
4. Ependymocytes
