Adult neurogenesis in the

580 7 months ago
Adult neurogenesis is the process in which neurons are generated from neural stem cells in the adult. This process differs from prenatal neurogenesis. In most mammals, new neurons are born throughout adulthood in two regions of the brain: [3]. More attention has been given to the neurogenesis in the dentate gyrus than in the striatum. In rodents , many of the newborn dentate gyrus neurons die shortly after they are born, [4] but a number of them become functionally integrated into the surrounding brain tissue.

Neurogenesis in adults: 4 ways to promote neurogenesis - Big Think

We can promote the development of new neurons well into adulthood - and here's why we should. Neurogenesis is still possible well into adulthood in two very important parts of the human brain. Image by EtiAmmos on Shutterstock. Although most people are aware that aging or bad habits such as heavy alcohol use can contribute to the deterioration of our brains, not many of us give thought to how we can generate new brain cells. Neurogenesis, the birth of neurons from stem cells, happens mostly before we are born - as we are formed in the womb, we are generating most of what we need after birth. Of course, when this information first came to light back in the s , the next natural question was: How do we promote neurogenesis in those areas where it's still possible? Researchers today believe there are activities you can do some of them may be things you already do on a daily basis that can promote neurogenesis in your brain.

Have you ever wondered how you can recognize a familiar friend in a busy environment? Social memory is the ability to recognize familiar others and is an essential function across species, not only for safety but also to maintain stable structures in complex and dynamic social networks. Social memory is involved in hierarchy formation, and defense, as well as mate, offspring, and interspecies recognition. A region of the brain called the hippocampus has long been pinpointed for its role in learning and memory generally; however, great strides have been taken recently to understand its role in social memory more specifically. When the CA2 region is lesioned, mice lose the ability to recognize familiar others.

Metrics details. Adult neurogenesis occurs throughout life in restricted brain regions in mammals. However, the number of neural stem cells NSCs that generate new neurons steadily decreases with age, resulting in a decrease in neurogenesis.
