The subventricular zone (SVZ) and the subgranular zone (SGZ) of neural progenitor cells generated neurons and glia in adulthood and during adulthood [14]. Neurogenesis also have a role in mood regulation; the dorsal hippocampus is an important region in memory formation and retrieval, whereas ventral hippocampus is an important region in emotions [15] . The spatial learning and memory retrieval in the MWM (Morris Water Maze) associated with neurogenesis Levels in MWM test of rats and…

    Alzheimer’s is a common neurodegenerative disease that accounts for the majority of all cases of dementia (Advokat, Comaty & Julien, 2014). Although the exact cause of Alzheimer’s is unknown, it is hypothesized that two systems crucial for the communication between brain cells fail due to the down regulation of acetylcholine and the over activation of glutamate, which result in the death of neurons (IOS Press, 2008). It is believed to involve the irreversible loss of cholinergic neurons,…
