Document Summary
Embryonic development: ectoderm thickens to form neural plate, neural plate invaginates/folds to form neural groove, neural groove fuses dorsally to form neural tube (closed by 28 days/4 weeks, neural plate develops into the brain & spc, b. Brain & ventricle development: pink = more tissue & less space (as brain gets bigger) Development: g, growth of dendrites & synapses at 15wks, layering of cortical neurons at. Cerebral cortex 6 layers: different staining methods stain different parts of the neuron, cortex is composed of 6 layers, layer 1: most superficial; next to pia mater, layer 6: deepest layer; next to white matter, c. Medium sized neurons, give rise to association and commissural fibres. Origins of projection fibres to basal ganglia, thalamus, brain stem, spc etc. I superficial; parallel to surface (pia mater) Iii medium sized neurons, give rise to association and commissural fibres; long fibres & short fibres.
