Zinc’s Role in the Brain
*Research gives insight into 50-year-old mystery – zinc important for learning and memory
TORONTO, ON – Zinc plays a critical role in regulating how neurons communicate with one another, and could affect how memories form and how we learn. The new research, in the current issue of Neuron, was authored by Xiao-an Zhang, now a chemistry professor at the University of Toronto Scarborough (UTSC), and colleagues at MIT and Duke University.
Researchers have been trying to pin down the role of zinc in the brain for more than fifty years, ever since scientists found high concentrations of the chemical in synaptic vesicles, a portion of the neuron that stores neurotransmitters. But it was hard to determine just what zinc’s function was. (more…)
