(14 cards)
Neurons in the part of the motor homunculus associated with the hip, knee, ankle and toes are irrigated by which vascular territory?
Anterior cerebral artery (ACA)
The frontal eye field (FEF) is located anterior to which of the gyri separating the frontal and parietal lobes?
Precentral gyrus
Unilateral frontal eye field damage causes abnormally frequent reflexive movements toward ____ targets:
(Bilateral, bilesional, contralateral, contralesional)
Contralesional
The supplementary motor area sits anterior or posterior to the primary motor cortex/M1?
Anterior
Frontal lobe atrophy in ____ Disease causes cognitive decline:
Alzheimer’s
Frontal lobe atrophy in ____ Disease causes decline in socially appropriate behaviour:
Pick’s
Working memory, as seen in the N-back task, causes increased activation in the prefrontal cortex of healthy adults, but is impaired in patients with dorsal and ____ lateral PFC damage:
Ventral
What aspect of memory is reliant on the prefrontal cortex being intact?
Working memory
The frontal lobe plays an important role in the ____ of a sequences of actions before they are executed:
Planning
The posterior/anterior/superior/inferior frontal lobe is believed to be associated with carrying out socially appropriate behaviour:
Anterior
Severe apraxia of the speech articulatory apparatus resulting in effortful, poorly articulated speech is called:
Aphemia
“Aphemia” may also be referred to as:
Foreign accent syndrome
