The brain is one of the most amazing parts of the body. It is a fascinating organ that controls everything that one does: thinking, paying attention, remembering, solving problems, controlling emotions and more. Dr Ronald Ngetich, a Neuroscience Researcher at the Institute for Human Development, Aga Khan University (AKU) explains that during early childhood, the brain has numerous neurons, (almost twice as many as the adult brain). However, as it develops, inactive neurons are cut off and communication between active ones is made better and smoother. Exercising, eating healthy foods, avoiding alcohol and drugs, sleeping well and keeping the brain active are all ways to take care of one’s brain, he writes.
