PSYC 370 Chapter Notes -Autism Spectrum, Granule Cell, Critical Period
Document Summary
Development of the nervous system. Chapter 9: induction of the neural plate, neural proliferation, migration and aggregation, axon growth and synapse development, neuron death and synapse rearrangement. Each of these will be discussed in greater detail. Ovum + sperm zygote. In order for the zygote to become a mature organism, there must be cell multiplication and Travelling to the correct location. Functional relationships with other cells. Layers of embryonic cells: ectoderm (outermost, mesoderm, endoderm (1) induction of the neural plate. Development of the neural plate begins with chemical signals from the organizer area. Background information on this listed below. The lips of the neural plate fold to form the neural groove. The neural tube is formed once the lips of the neural groove close. Eventually becomes the cerebral ventricles and spinal canal. Neural plate: small patch of ectodermal tissue on the dorsal surface of the developing embryo. The development of the neural plate is the first major step of neurodevelopment.
