NEW335H1 Lecture Notes - Lecture 4: Magnetic Resonance Imaging, Grey Matter, Neuroplasticity
Document Summary
Mechanism of major changes (structural/functional) in the brain- now known to occur even outside the critical period (first five years). Could be macro- visible using neuroimaging tech (neurogenesis/ mylelin formation) Micro (changes in each individual neuron part (i. e. receptor, neurotransmitter release, neuronal firing rate, myelination. Not really, change can be for the worse. See question 2: understand the terms gray matter, white matter, cell body, axon, cortex and tract. Cortex= outer layer of cells (gray matter)/ phylogenetically new/ higher order behaviours. Frontal/ temporal/parietal/ occipital: answer the following questions about magnetic resonance imaging (mri) and functional mri (fmri), what a(cid:396)e these te(cid:272)hni(cid:395)ues used fo(cid:396)? (cid:271). Give the full name of each brain region not just the acronym. a. To answer this question, make sure to consider the elements of meditative practices (also covered in lecture 1) b. For each area identified, describe some potential behavioral consequences of meditation-induced neuroplasticity.
