Neurogenesis is the process by which neurons are generated from neural stem cells.Developmental neurogenesis and adult neurogenesis differ markedly; this article is limited in scope to adult neurogenesis.
A milestone is marked in our understanding of the brain with the recent acceptance, contrary to early ma, that the adult nervous system can generate new neurons.
Neurogenesis occurs in two main areas in the adult brain: the hippocampus and the olfactory bulb.; The transformation of a new cell into a neuron appears to crucially involve a specific protein called WnT3, that’s released by support cells called astrocytes.
Adult neurogenesis is the process of generating new neurons which integrate into existing circuits after fetal and early postnatal development has ceased. In most mammalian species, adult neurogenesis only appears to occur in the olfactory bulb and the hippocampus.
Recent research demonstrates that neural stem cells divide throughout life and give rise to new neurons, a process known as neurogenesis.
Conventional wisdom has long suggested that we can’t grow new brain cells, but recent research has shown the neurogenesis in adults is, in fact, possible.
May 26, 2011 · Adult neurogenesis, a process of generating functional neurons from adult neural precursors, occurs throughout life in restricted brain regions in mammals. The past decade has witnessed tremendous progress in addressing questions related to almost every aspect of adult neurogenesis in the mammalian
I borrowed the first version of this book (Adult Neurogenesis) from my institution’s library and put off buying this updated version for far to long because of the price.
It could even be that an increase above baseline of adult neurogenesis improves learning AND this is still true – I can think of two possible explanations:
Retrospective carbon dating of human hippocampal cells confirms substantial adult neurogenesis and suggests that the process contributes to brain function.
