PSYB65H3 Lecture 3: Detailed Lecture #3 Notes
Document Summary
Week 3 lecture #3: wednesday september 23, 2015. Stem cells can become neurons and glial cells. A chemical compound that acts to support growth and differentiation in developing neurons. Stages of brain development: cell birth (neurogenesis; gliogenesis, cell migration, cell differentiation, cell maturation (dendrite and axon growth, synaptogenesis (formation of synapses, cell death and synaptic pruning, myelogenesis (formation of myelin) Cell birth (neurogenesis; gilogenesis: a chemical compound acts to support growth and differentiation in developing neurons; Neurons die that doesn"t play a role or in use. Grows and try to connect to other neurons. If occurs after the injury will be much more severe. Migration: begins shortly after first neurons are generated, continues for 6 weeks in cortex and longer in hippocampus, damage has more serious consequences. Radial glial cell: path-making cell that a migrating neuron follows to its appropriate destination.
