After training rats to successfully navigate a maze,Karl Lashely sought to determine the precise spot in the brain where the learning occurred by:
A)surgically removing tiny sections of the brain and then retesting the rats.
B)giving the rats experimental drugs that target specific brain areas and then retesting the rats.
C)studying differences in dendritic density in various brain regions under a microscope after the rats' death.

Question

Quizplus · Accepted Answer

Karl Lashely sought to determine the precise spot in the brain where the learning occurred by surgically removing tiny sections of the brain and then retesting the rats. This allowed him to observe the effect of removing different regions, and by comparing the results, he could identify which areas were most critical for navigation and learning. Therefore, option A is the best choice.
