PSC 101 Lecture Notes - Lecture 7: Visual Cortex, Intellectual Disability, Transcranial Magnetic Stimulation
Document Summary
New neurons and glial cells are formed in a part of the neural tube called the ventricular zone. Neurons themselves do not divide (but they are a product of cell division) Cell migration cells move to establish distinct populations. During cell migration, cells move away from the ventricular layer. Radial glial cells act as guides for cells to migrate along. Differentiation cells become distinctive neurons or glial cells. When cells reach their destinations, they begin to express genes to make proteins they need. Cell differentiation allows a cell to acquire its specific appearance and function. Cell-autonomous independent of other cells and driven by genes, intrinsic organization as seen in in vitro". Neural environment differentiation affected by other cells. Both axons and dendrites grow extensively, forming many synapses, this process is guided by chemicals released by the target cells. Chemoattractants chemical signals that attract growing axons. Neuronal cell death selective death of some nerve cells.
