Keep sharp1/31/2024 There are billions of neurons, or brain cells, in the human brain, and trillions of synapses through which information is transmitted from one neuron to another via electrical signals. We now know, however, that much of the brain’s power and complexity comes not from the individual sections, but from the communication between each section.Ĭommunication within the brain happens between neurons through synaptic connections, writes Gupta. This led to the debunked theory that people are either left- or right-brain dominant. Not too long ago, it was thought that the brain was split up into separate parts that acted on their own: One part of the brain was used for abstract thinking, another for interpreting language. Because of this, we should focus on improving the functions of every part of the brain, not just the areas we may deem most important. Gupta claims that our growing understanding of the brain has taught us that different parts of the brain function in a highly coordinated manner. With regard to improving brain health, there are two key attributes of the brain you should understand: interconnectedness and neuroplasticity. Gupta argues that to better understand how to improve your brain, you must first understand how it works. While these may seem like obvious components of a healthy lifestyle, we’ll show how important they are for a healthy brain specifically. Gupta explores five key components of brain health: exercise, sleep, nutrition, discovery, and connection. For Keep Sharp, Sanjay Gupta interviewed some of the leading experts on neuroscience and reviewed the latest research.
