Tiny Brains

Microscopic networks of neural cells known as “minibrains” can teach researchers about diseases ranging from Alzheimer’s to Zika. The minibrains, which mimic the embryonic human brain, have allowed researchers Thomas Hartung, of the Johns Hopkins Bloomberg School of Public Health, and Hongjun Song, of Johns Hopkins Medicine, to study the progression of Zika infection in fetuses. The team will present its findings this week at the Society for Neuroscience meeting in San Diego.
Minibrains, which were developed a few years ago in Europe, will see increasingly wide usage in researching other diseases, including Alzheimer’s and Parkinson’s.
