Brain-Derived Neurotrophic Factor (BDNF) is a protein that plays a crucial role in the growth, maintenance, and survival of neurons. It is a member of the neurotrophin family of growth factors, which are related to the nerve growth factor (NGF). BDNF is widely expressed in the central nervous system (CNS), particularly in regions such as the hippocampus, cortex, and basal forebrain, which are vital for learning, memory, and higher cognitive functions.
