Document Summary

Alds 3604 brain imaging techniques, learning, and neuroplasticity. Understand basic neural correlates of learning, neuroplasticity & (re)habilitation. Understand basic features of most currently used brain imaging techniques. Understand role that these techniques play in furthering knowledge of language learning. Neurons (dendrites; cell bodies (gray matter); axons (white matter/fibre tracts 1mm to. Pns schwann cells control myelination; cns oligodendrocytes control myelination. Brain stem reticular formulation (alertness, consciousness) Cerebellum (coordination of movement, motor learning, posture) Neural development: mediated by genetics, newborn neurons develop mostly prior to birth (location & connectivity determined in utero, continuous after birth as well. Neuroplasticity: neural changes due to external stimuli (sensory, changes due to internal reorganization. Most neurons developed by 25th gestational week (possible neurogenesis later in hippocampus, olfactory region & cerebellum) Neural tube differentiates into various parts of brain (cerebrum, brain stem, spinal cord, 350% increase in brain size in 1st 2 yrs. Great increase in surface area & folding of cerebral cortex.
