New neurons form in two areas of the brain, well into adulthood. The hippocampus, one of those brain areas, is critical for learning and memory. Changes in neurogenesis due to aging, depression, stress, hormones or injury adversely affect these critical functions. Neuronascent's scientists aim to enhance neurogenesis, to promote greater numbers of mature neurons that will subsequently promote cognitive improvement in patients with Alzheimer's disease, depression, or stroke.
