What is New Brain Cells?

New brain cells, also known as neurons, have the ability to regenerate throughout a person’s life. This means that healthy individuals can gain new neurons and improve their overall cognitive function even into old age. The development of these new cells occurs in several areas of the brain, such as the hippocampus and olfactory bulb, allowing for improved learning, memory formation, and enhanced senses. To understand why these new neurons are created it is important to first know how our brains work. Neurons are responsible for transmitting messages between parts of the body by sending electrical signals down axons and then relaying information onto another neuron via chemical synapses. As we learn more about ourselves and engage in different activities our brains form new pathways between neurons enabling them to send stronger signals through better connections. Recent research has found that with increased neuronal activity there is an increase in production of stem cells which eventually develop into fully functioning brain cells. With repeated stimulation over time this process results in a net gain of new synaptic pathways leading to increased cognitive performance potential or ‘brain plasticity’ as it is commonly referred to by scientists. The creation of these new brain cells allows us to continue forming long-term memories despite advancing age; however there are still many unanswered questions regarding its full extent and benefits on cognition later on in life. For example some studies have shown that Alzheimers patients may benefit from stem cell therapy while others suggest that neuronal regeneration does not necessarily prevent dementia symptoms but rather slow down their progression once they appear. While much remains unknown about this process one thing is certain: when combined with other lifestyle changes such as exercise, good nutrition, mental stimulation etc., our bodies can continually generate fresh neural connections capable of enhancing existing abilities or perhaps even creating brand-new ones.
