Neurology Flashcard Deck - 10 Cards
Flashcard 301: A right parietal lobe lesion results in _____
Answer: left homonymous inferior quadrantanopia
Extra: Mnemonic: P-I-G (Parietal - Inferior - Gyrus/Loop) or 'Pie on the floor'.
Temporal lobe lesions involve Meyer's loop and cause superior quadrantanopia ('Pie in the sky').
Flashcard 302: Contralateral homonymous inferior quadrantanopia is a visual field defect associated with a lesion to the _____ lobe
Answer: parietal
Flashcard 303: The visual fields are subdivided into _____ & temporal hemifields
Answer: nasal
Flashcard 304: What visual field defect results from an infarct to the PCA artery affecting the primary visual cortex?
_____
Answer: Contralateral homonymous hemianopia with macular sparing
Flashcard 305: What visual field defect results from a lesion of the temporal lobe (e.g. MCA infarct)?
_____
Answer: Contralateral homonymous superior quadrantanopia
Flashcard 306: Visual images perceived in the temporal hemifield will stimulate cells on the _____ half of the ipsilateral retina (and vice versa)
Answer: nasal
Flashcard 307: Bitemporal hemianopia is a visual field defect associated with a lesion to the _____
Answer: optic chiasm
Flashcard 308: A lesion in the **right visual cortex** (e.g., PCA stroke) typically results in what visual field defect? \n\n_____
Answer: Left contralateral homonymous hemianopia with macular sparing
Extra: Macular sparing in PCA strokes occurs because the macula receives dual blood supply from both the Posterior Cerebral Artery (PCA) and the Middle Cerebral Artery (MCA).
Flashcard 309: A lesion in the **Meyer's loop** (temporal lobe) results in which visual field defect?\n\nAnswer: _____
Answer: Contralateral homonymous superior quadrantanopia
Extra: Mnemonic: **M**eyer's loop = **T**emporal lobe = **S**uperior defect (\"Pie in the sky\").\n**P**arietal lobe (Baum's loop) = **I**nferior defect (\"Pie on the floor\").
Flashcard 310: Monocular anopia is a visual field defect associated with a complete lesion to the _____
Answer: optic nerve
