Which concept describes Lashley's finding that some functions are localized while others are widely distributed?

• A. Localization
• B. Localization criticisms
• C. Neuroplasticity
• D. Dendritic branching

Answer: (B)

Lashley’s work pushes against a strictly localized view by showing that some cognitive functions rely on distributed networks across the cortex, while others may show more localized involvement. This nuanced picture is captured by localization criticisms, which argue that mapping brain regions to specific functions isn’t an all-or-nothing rule: some functions are localized, but many important processes rely on widespread neural networks. Lashley’s findings—especially that the effects of cortical damage depended on the amount of tissue damaged more than on a single spot, and the idea of equipotentiality where memories are distributed—support this critical stance against pure localization. The other terms don’t fit as well: localization would imply functions are entirely confined to specific areas; neuroplasticity concerns the brain’s ability to change with experience; dendritic branching is a cellular feature unrelated to this debate about where functions are localized versus distributed.
