The main focus of neurobiology is to understand the structure, function, and development of the nervous system. This interdisciplinary field examines cellular and molecular mechanisms that govern neuron function, synaptic communication, and how the brain processes information. Research in neurobiology plays a critical role in addressing neurological disorders such as Alzheimer's, Parkinson's, and multiple sclerosis. By studying these complex neural networks, scientists aim to develop treatments and improve overall brain health.
