From the moment the scientists across the world established that the elevated attentiveness of several substance in synaptic vesicles, which is generally identified as an important portion of the neuron, which supplies neurotransmitters, till date the researchers have been trying hard to fix the role of zinc in the functioning of the brain.

Of late, zinc has made its presence felt in the medical arena both as a helper and a threat, if present in excess.

Now, scientists at the University of Toronto Scarborough (UTSC), and colleagues at MIT and Duke University have found that zinc plays a key role in regulating how neurons communicate with one another, and could affect how memories form and how we learn.

The researchers studied neurons in a brain region called the hippocampus, which is associated with learning and memory formation. They found that removing zinc interfered with a process called long-term potentiation, which strengthens the connection between two neurons, and is believed to be important for memory and learning.
