Grow Little Cell Grow! Investigating Neurogenesis Essay -- Biology Ess

Grow Little Cell Grow Investigating NeurogenesisNeurogenesis, the intersection of new hardiness cells, has been a revolutionary finding as nerve formation has always been thought to end with adulthood. It has not been until recently that such(prenominal) dogma has been contradicted as research findings report that neurogenesis continues in the genus Hippocampus passim most of the adult life of mammals and primates (1). Recent correlations turn over been moreover made between neurogenesis and depression as the latter depletes nerve cell cells in the brain while antidepressive drugs have show to increase neuronal return (2). Neurons are the building blocks of the nervous system as they are amenable for the input, processing and transmission of information. Neurons are derived from stem cells as the latter strike off into specialized cells and make progenitor cells which are responsible for the formation of neuron and glial cells. Although the majority of neurons are formed dur ing the pre-natal and perinatal stage of development, neuron formation continues in the dentate gyrus of the hippocampus (2). The hippocampus, which lies beneath the cerebral mantle is a major factor of learning and memory formation and grass indirectly influence emotion. Progenitor cells which are present in the numbfish ventricular zone of the hippocampus are responsible for such result as they produce daughter neuron cells through division (2). In the 1960s, Joseph Altman from MIT reported that new neurons were being produced in the dentate gyrus of the hippocampus of adult rat brains. Although such findings were groundbreaking, they failed to create the stir that Elizabeth Goulds 1998 study caused . The Princeton University neurobiologist demonstrated that the marmoset b... ...is is a complex issue with an array of possibilities for the future.
