New nerve cells formed in a select part of the brain could hold considerable sway over how much you eat and consequently weigh, new animal research by Johns Hopkins scientists suggests in a study published in the May issue of Nature Neuroscience.
The idea that the brain is still forming new nerve cells, or neurons, into adulthood has become well-established over the past several decades, says study leader Seth Blackshaw, Ph.D., an associate professor in the Solomon H. Snyder Department of Neuroscience at the Johns Hopkins University School of Medicine. However, he adds, researchers had previously thought that this process, called neurogenesis, only occurs in two brain areas: the hippocampus, involved in memory, and the olfactory bulb, involved in smell.
