Neurogenesis is the process by which nervous system cells, the neurons, are produced by neural stem cells (NSCs). It occurs in all species of animals except the porifera (sponges) and placozoans. Types of NSCs include neuroepithelial cells (NECs), radial glial cells (RGCs), basal progenitors (BPs), intermediate neuronal precursors (INPs), subventricular zone astrocytes, and subgranular zo… giada\\u0027s christmas cookiesWebApr 14, 2024 · Stress is an ambiguous and transdisciplinary concept we used from material science to physiology and ecology [62,93,94], encompassing different meanings: certain stimuli can be stressors; the emergency responses to the stressor is defined as the stress response; and chronic stress is the over-stimulation of the emergency responses .
