Decerebrate posturing is hypothesized to occur in response to activation of this type of motor neurons
Gamma
This layer of cerebral cortex contains inter cortical afferent and efferent connections
Layer III
oligodendroglioma
The most common reason for an "abnormal" lumbar vertebral count
S1 lumbar type vertebrae
Seizures, bulbar dysfunction, encephalopathy after a mosquito bite
cerebral malaria
This PICA segment typically gives rise to choroidal branches
Telovelotonsilar
Neurofibrillary tangles, Alzheimer's Disease
Hemangiopericytoma (solitary fibrous tumor)
The anterior limb of the internal capsule is supplied by this vessel
Heubner's Artery
The most important variable in the success of an ETV
Age
The mammillothalamic tract joins the mammillary bodies to this group of thalamic nuclei
Anterior nuclear group
DNET
The most common pathologic subtype of meningioma
Transitional (mixed)
Crosses cribriform plate and can exist in flagellate form in CSF
Naegleria fowleri
Structure c:
Mamillary bodies
The ventral surface of the dura mater in the lumbar spine is innervated by this nerve
Segmental sinuvertebral nerve
This lesion is most likely supplied by branches of this parent vessel:
ophthalmic artery (ethmoidal arteries)
Dysembryplastic Neuroepithelial Tumor
Patients with a <7mm posterior circulation aneurysm and no history of SAH are at this risk of rupture over 5 years
2.5% (ISUIA)
Germinal Matrix Hemorrhage
The output tract of the amygdala forms this structure
stria terminalis
glioblastoma (pseudopalisading necrosis)
Historically, these three criteria are used to predict patient survival after surgery for high grade gliomas
1. Age
2. Extent of Resection
3. KPS
Structure #2 is......
Inferior Cerebellar Peduncle
Sudden death in a 20 year old
Colloid cyst
