This neurofibrillary tangle is from a 7-month old mouse brain. The picture shows a healthy neuron to the right and a damaged neuron to the left. The black coloration is accumulations of toxic tau protein. University researchers now suspect that neurofibrillary tangles are a symptom of Alzheimer's, not a cause of the disease.
