PSYC55H3 Study Guide - Midterm Guide: Orbitofrontal Cortex, Global Aphasia, Habituation
Document Summary
E. g. , when the injection is to the left side, the patient"s ability to speak or comprehend speech is disrupted for several minutes: then the patient is engaged in a series of tests related to language and memory. Regions of the right hemisphere, however, are also engaged, especially for language tasks that require higher-level comprehension. Anterior commissure: smaller band of fibers connecting the two hemispheres. About 1/10 the size of the corpus callosum. Found inferior to the anterior portion of the corpus callosum, and primarily connects certain regions of the temporal lobes, including the two amygdalae. Located above the cerebral aqueduct at the junction of the third ventricle. Contains fibers that contribute to the papillary light reflex. Located beneath the cortex and runs along the longitudinal fissure: divided on a macroscopic level into: The anterior portion of the corpus callosum. Involved in the higher order transfer of semantic information. The middle portion of the corpus callosum.
