what led to the myth that humans use only 10 percent of our brains?
a scientists electrically probed the association areas of the brain and received no response.
b \scientists noticed that when they severed the corpus callosum of most patients, it had no effect on their behavior.\
c phineas gages horrible accident had no detectable effect on his brain.
d this is not a myth; humans use only 10 percent of the brain.

Explanation:

The myth that humans use only 10 percent of their brains originated in part from early neuroscience experiments where scientists electrically probed the association areas of the brain and received no obvious responses, leading to the idea that those areas were not in use. Severing the corpus callosum (option B) is related to split - brain research and not the origin of this myth. Phineas Gage's accident (option C) was about brain - behavior relationships but not the cause of this myth. And it is indeed a myth that humans use only 10 percent of their brain (contrary to option D).

Answer:

A. Scientists electrically probed the association areas of the brain and received no response.
