The ‘missing-link’: Establishing the First Mammalian Model System for Investigating Vocal Learning and its Clinical Pathology

by Michael Yartsev, Ph.D.

Vocal learning, or the ability to hear a sound or word, imitate it, and develop language is often thought of as a required or necessary human ability, so much so that the lack of appropriate language acquisition is a hallmark of many neurological ...

Brain PET Imaging of Synaptic Density in Alzheimer’s Dementia

by Ming-Kai Chen, M.D., Ph.D.

Can a new PET imaging tracer outperform the currently used one in diagnosing Alzheimer’s disease (AD) and in monitoring its progression?Diagnosing probable AD currently relies on three major measures. One is whether there is a decrease in glucose ...

The role of iron in Alzheimer's disease

by Michael Zeineh, Ph.D., M.D.

Might inflammation arising from iron that is converted into an active state in the brain be the third leg of the Alzheimer’s disease (AD) stool, joining the abnormal proteins “amyloid” and “tau” as the hallmarks of AD? Stanford investigators will...

Using Pharmacological fMRI to Develop Novel Therapies for Treating Depression

by Jennifer Felger, M.S., Ph.D.

Some patients being treated for depression continue to lack motivation to engage in potentially rewarding behaviors, like social interactions, and this problem may be related to inflammation that impedes communication among reward-related brain a...
