Neuroscience is the scientific field that studies the structure and function of the nervous system, including the brain, spinal cord, and peripheral nerves. It encompasses various disciplines such as biology, psychology, and medicine to understand how the nervous system affects behavior, cognition, emotions, and physiological processes. Neuroscience investigates the development, organization, and functioning of neural networks, aiming to elucidate the underlying mechanisms of neurological disorders and promote insights into brain health and function. This field employs techniques from molecular and cellular biology, neuroimaging, and computational modeling to advance knowledge about neural processes and contribute to the development of treatments for brain-related conditions.
Age-related cognitive decline starts subtly in our 30s, with brain shrinkage occurring over time. Common signs of aging include forgetfulness, wavering concentration, and changing emotional responses. By age 80, brain…
