Findings by Lashley in which a rat showed deficits in maze navigation proportional to the total amount of cortex removed from the brain best demonstrates ______.
A)cognitive functions are highly specific to and recruit particular brain regions
B)cognitive functions can be spread across and recruit multiple brain regions
C)cognitive functions are independent of the physical brain
D)cognitive functions cannot operate with any damage to the physical brain

Question

Lashley's findings suggest that cognitive functions, such as maze navigation in rats, are not localized to specific brain regions but rather are distributed across the cortex. This is because the deficits observed were proportional to the amount of cortex removed, not the specific location of the removal, indicating that cognitive functions can recruit multiple brain regions.
