Question

Quizplus · Accepted Answer

Senile plaques are formed by deposits of beta-amyloid protein that accumulate between neurons, while neurofibrillary tangles are made up of twisted threads of tau protein that form inside neurons. Therefore, senile plaques are found between neurons in the brain, while neurofibrillary tangles are found within neurons in the brain.
