The staining of Thioflavin S (in green) on adjacent sections of the hippocampus of a patient suffering from&nbsp;Alzheimer's disease. Thioflavin S binds both&nbsp;senile plaques&nbsp;(SP) and&nbsp;neurofibrillary tangles&nbsp;(NFT), the two characteristic cortical lesions of Alzheimer's. Amyloid beta is a peptide derived from the&nbsp;amyloid precursor protein&nbsp;which is only found in senile plaques, and so only plaques are visible in the right hand image.
