LIGN 148 Lecture Notes - Lecture 13: Corpus Callosum, Grey Matter, Avocado
Document Summary
Some brain facts: your brain uses 20% of body energy, but i only 2% of your body. If you could harness the power used by your brain, you could illuminate a. It would take ~171 years to count them. Basic brain anatomy: two cerebral hemispheres, connected by corpus callosum, gyri = bumps, sulci = grooves, white matter = axons, grey matter = cell bodies, ~100 billion neurons, ~1000 trillion (1015) synapses. Basic structure: cortex, 2 hemispheres, corpus callosum, contralateral control. Ipsilateral control: subcortical structures, cerebral lobes, cerebrum divided into lobes, named after the bones of the skull that lie over them, central sulcus, divides frontal lobes and parietal lobe, sylvian fissure, between frontal/parietal and temporal lobes. How to investigate sign language in the brain: brain anomalies, left vs right hemisphere brain damage, stroke, cortical language mapping in left hemisphere. Spoken language processing: lesions to the left hemisphere frontal regions (ifg) result in broca"s aphasia:
