- MCAT · medium1. A 34-year-old man with a history of rheumatoid arthritis presents with acute onset headache, fever (38.9°C), and photophobia. MRI brain shows meningeal enhancement. CSF analysis…
- MCAT · medium2. A 68-year-old man with mild cognitive impairment undergoes neuropsychological testing as part of a research study on memory and synaptic plasticity. Researchers use hippocampal…
- MCAT · medium3. A 68-year-old woman presents with progressive memory loss and cognitive decline over the past 2 years. Brain MRI shows cerebral atrophy and her cerebrospinal fluid analysis reve…
- MCAT · medium4. A neurotoxicology study examines a compound that selectively inhibits vesicular monoamine transporter 2 (VMAT2) in dopaminergic neurons. This transporter normally sequesters cyt…
- MCAT · medium5. A 58-year-old man presents with a 6-month history of progressive incoordination and difficulty with fine motor tasks. He reports dropping objects and having trouble with rapid a…
- MCAT · medium6. A 54-year-old man with a 6-month history of visual hallucinations undergoes neuroimaging that reveals a small cell lung cancer with metastases to the visual cortex. His hallucin…
- MCAT · medium7. A 68-year-old man presents with progressive vision loss, particularly difficulty with night vision and peripheral visual field defects. Genetic testing reveals a mutation in the…
- MCAT · medium8. A 68-year-old man presents with a 3-year history of progressive bradykinesia, resting tremor, and rigidity. Over the past year, he has developed visual hallucinations and fluctu…
- MCAT · medium9. A neuroscientist administers an antagonist of N-methyl-D-aspartate (NMDA) receptors to experimental animals and observes impaired performance on spatial memory tasks dependent o…
- MCAT · medium10. Long-term potentiation (LTP) is induced in hippocampal CA1 neurons following high-frequency stimulation of Schaffer collaterals. This triggers calcium influx through NMDA recept…
- MCAT · medium11. A patient suffers a stroke affecting the left middle cerebral artery (MCA) territory, resulting in damage to Broca's area. Clinical assessment reveals non-fluent speech producti…
- MCAT · medium12. During synaptic transmission, an action potential triggers voltage-gated calcium channels to open in the presynaptic terminal, allowing calcium influx. This calcium influx promo…
- MCAT · medium13. A researcher observes that lesions in the ventromedial prefrontal cortex (vmPFC) impair decision-making involving reward evaluation. Electrophysiological recordings show reduced…
