PSYC 208 Lecture Notes - Lecture 6: Neural Tube, Neural Development, Synaptogenesis
Document Summary
Destination, they will develop and specialise into the neuron. Formation of neural tube (neuralisation) top of the neural tube = forebrain. Midbrain = sits on the brain stem. Hindbrain - near the cerebellum, medulla, pons. Beings to curve, the brain begins to develop after 5 weeks. Neuronal proliferation - generation of neurons and brain cells - making up of glial cells. Differentiation: immature neuron all look similar so when they reach their final. Beings around week 5 and extends well into the 3rd trimester. Cortical neurons (neurons for the cortex) arise from precursor cells in the. When the brain is formed the deeper areas are formed first (inside areas first, superficial areas are developed later) Ependymal layer - wall of the ventricle. Neurons travel through the white matter (connections between neurons) to the cortical number of units (connected to different radial glial cells) in the ventricular zone increases layer (gray matter) Determines how the brain folds and is wired.
