PSYB65H3 Chapter Notes - Chapter 4: Lateral Sulcus, Spatial Frequency, Commissure
Document Summary
Laterality: functional specialization of the right and left hemispheres. Left hemisphere (lh)-> language and right body control. Right hemisphere (rh)-> music, emotion, spatial abilities, left body control. Rh capabilities took longer to understand-> damage resulted in subtle differences compared to lh. Although methods expressed is in separate lh and rh methods, the two often intermingle and are in constant communication eg) sarcastically said: nice shoes"; lh interprets the words, rh interprets the tone. >prosody: sound waves that compose emotional tone of speech. > anterior + posterior commissures, corpus collosum, habenular commissure, hippocampal commissure. When the corpus collosum is severed, communication b/w lh and rh is severed. When it continued, the cut the remaining commissural system, stopping the seizures. With the two separated, rh does not deal with writing, was incapable of arranging letters. Intracarotid amobarbital testing eg) injection into the right carotid artery results in right side of the brain sleeping".
