Brain Stories Exam 1 Questions And Verified Answers | 100% Module 1: Aneurysm - ANSWER A weak thin spot on a blood vessel that causes the vessel to dilate or balloon -Rupture of an aneurysm causes hemorrhage Axon - ANSWER A long, thin projection from a neuron that carries electrical impulses from the cell body Broadmann's areas - ANSWER a classification of areas of the cerebral cortex according to assigned numbers Cerebral Cortex - ANSWER The narrow zone of grey matter that lies at the surface of the cerebrum -the grey matter lies external to the white matter in the cerebrum -the reverse is true in the spinal cord Closed-head Injury - ANSWER a traumatic brain injury in which the skull is not pierced by the external force, thus stays intact Contusion - ANSWER a bruise that forms around the site of impact of a traumatic brain injury due to laceration of blood vessels Corpus Callosum - ANSWER the major connecting pathway between the right and left hemispheres CT Scan - ANSWER -Computerized tomography An imaging technique that allows scientists to identify lesions in the brain of LIVE patients Diffuse Axonal Injury - ANSWER microscopic damage incurred diffusely throughout the brain, associated with traumatic brain injury, that includes the shearing of axons from their myelin sheath or tearing of the axons themselves Modularity Theory - ANSWER the notion that certain brain functions are mediated by specific anatomical areas of the brain Phrenology - ANSWER Put forward by Gall in 1796 and based on modularity of mind theory, the notion that PERSONALITY traits of a person can be derived from examination of the shape of the skull Double Dissociation - ANSWER refers to two cognitive faculties that are believed to be linked in some way where each can receive damage while the other remains intact and functioning Dualism - ANSWER a philosophy of mind suggested that mental phenomena are essentially non-physical, thus distinguishable from brainfunction EEG - ANSWER -electroencephalography a method by which gross electrical activity in the brain is measured fMRI - ANSWER -functional magnetic resonance imaging provides images of changes in blood oxygenation within the brain that are used to identify brain areas that are active during specific cognitive and linguistic tasks Information Processing Model - ANSWER an approach to the goal of understanding human thinking arising in the 1940s and 1950s -the essence of the approach is to see cognition as being essentially computational in nature, with mind being the the software and the brain being the hardware MRI - ANSWER -magnetic resonance imaging a non-invasive imaging technique that allows scientists to identify brain lesions in live patients Neuron - ANSWER nerve cell -contain a cell body, dendrites, and an axon Open-head Injury - ANSWER traumatic brain injury in which the skull is fractured or penetrated by an external force and the contents of the skulls are exposed Perseveration - ANSWER the tendency to repeat the same (to similar) response despite it no longer being appropriate Stroke - ANSWER any disruption in blood flow to the brain -also called cerebrovascular accident (CVA) or brain attack Tumors - ANSWER -or neoplasms tissue masses that arise from an abnormally fast rate of cell production Traumatic Brain Injury - ANSWER TBI -an insult to the brain produced by external forces that may cause a variety of temporary or permanent physical, cognitive, and behavioral impairments Module 2: Agnosia - ANSWER impaired ability to recognize what is "sensed" in spite of intact sensory function
