Tau protein in patient's brain
Photographer: Karolinska Institutet
The images show tau deposits in the brain of a patient with early-stage Alzheimer’s disease. The warm colours indicate regions of heavy deposition and the difference in spread between the patient’s first scan (to the left) and second scan 17 months later (to the right). The tau deposits were measured using the radioligand THK5317. Photo: Karolinska Institutet
