By Stephanie Dutchen, HMS Writer/Editor

It used to be enough to call a serotonergic neuron a serotonergic neuron.

These brain cells make the neurotransmitter serotonin, which helps regulate mood, appetite, breathing rate, body temperature and more.

Recently, however, scientists have begun to learn that these neurons differ from one another—and that the differences likely matter in dysfunction and disease.

Neurons reprogrammed in animals

November 4, 2015

Building on earlier work in which they disproved neurobiology dogma by “reprogramming” neurons — turning one form of neuron into another — in the brains of living animals, Harvard Stem Cell Institute researchers have now shown that the networks of communication among reprogrammed neurons and their neighbors can also be changed, or “rewired.”

The finding, by Paola Arlotta, a professor of… Read more about Neurons reprogrammed in animals
