doughnut-shaped neural system (including the hippocampus, amygdala, and hypothalamus) located below the cerebral hemispheres; associated with emotions and drives. Application: Roger Sperry received the Nobel prize in 1981 for his pioneering research on brain specialization in split-brain patients. They range from the skin sores associated with eczema to the changes in lung tissue that occur in tuberculosis. cells in the nervous system that support, nourish, and protect neurons. Lesion Method. Lesion is a broad term, including wounds, sores, ulcers, tumors, cataracts, and any other tissue damage. The abnormality is seen as spots which … While the definition sounds simple, understanding brain lesions can be complicated. controls language expression—an area, usually in the left frontal lobe, that directs the muscle movements involved in speech. Definition: finds that when the brain was divided each hemisphere continued to have individual and private experiences, sensations, thoughts, and emotions. Sometimes doctors say they "lesioned an area" which means they purposely damaged the tissue in that area. areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather, they are involved in higher mental functions such as learning, remembering, thinking, and speaking. Chapter 14: Industrial and Organizational Psychology. Skin lesions can be inherited or caused by inflammation, injury, or disease. the principle that information is often simultaneously processed on separate conscious and unconscious tracks. the brain's sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla. A lesion is damage to a part of the brain that results in destruction to the neurons. Lesion: damage to biological tissue, often due to trauma. a technique for revealing bloodflow and, therefore, brain activity by comparing successive MRI scans. Traumatically induced lesions, including excoriations caused by the patient's fingernails, are typically linear. a neural structure lying below (hypo) the thalamus; it directs several maintenance activities (eating, drinking, body temperature), helps govern the endocrine system via the pituitary gland, and is linked to emotion and reward. Learn ap psychology brain scans with free interactive flashcards. Start studying AP Psychology Unit 3B. two lima bean-sized neural clusters in the limbic system; linked to emotion. the acquisition of a traditional masculing or feminine role. Definition: tissue destruction; a brain lesion is a naturally or experimentally caused destruction of brain tissue, Definition: an amplified recording of the waves of electrical activity that sweep across the brain's surface. These waves are measured by electrodes placed on the scalp. How are Brain Lesions Treated? a raised lesion, measuring less than 1 centimeter, on the surface of the skin, filled with pus an elevated patch of skin, confined to the upper epidermis, usually with a reddish border and pale center our awareness of ourselves and our environment. Chapter 15: Psychological Disorders. the base of the brainstem; controls heartbeat and breathing. the subfield of psychology that studies the molecular structure and function of genes. Secondary skin lesions are a progression of primary skin lesions. Definition. LESION: "Cuts, bruises and open wounds are otherwise known as lesions." Recent Examples on the Web The culprit was the old lesion in his T5 vertebra that had been radiated three years earlier. Chapter 13: Social Psychology. the interdisciplinary study of the brain activity linked with cognition (including perception, thinking, memory, and language). controls language reception—a brain area involved in language comprehension and expression; usually in the left temporal lobe. Psychology Definition of CORPUS CALLOSUM: an immense pathway of nerve fibers traveling over the longitudinal fissure of the brain and linking the cerebral hemispheres. Like Wernicke, Broca found lesions in the brains of these patients. MRI scans show brain anatomy. Here is information about this confusing and unsettling health concern. Lesion methods are when lesions to a specific part of the brain are deliberately created. any pathological or traumatic discontinuity of tissue or loss of function of a part. a single wound or opening which would otherwise be abnormal and unexpected in a tissue - a tissue is a group of cells in the human body. The School of Psychology and Neuroscience has an international reputation for the quality of its research and has consistently been ranked one of the best research departments in the UK. In … DuVerney was the first to use experimental ablationmethod on animals in 1679. Term. Psychology Definition of BRAIN LESION: n. any abnormal, damaged area of tissue detected in the brain. Sometimes doctors say they "lesioned an area" which means they purposely damaged the tissue in that area. a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task. a technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue. The lesions to be made in Matthew's cingulum are anatomically "miles" from the frontal lobe, but the changes -- the calming, flattening -- they produce will be somewhat similar. the oldest part and central core of the brain, beginning where the spinal cord swells as it enters the skull; the brainstem is responsible for automatic survival functions. a condition resulting from surgery that isolates the brain's two hemispheres by cutting the fibers (mainly those of the corpus callosum) connecting them. How serious are brain lesions and how are they treated? In neuroscience, a lesion generally refers to damage to the brain. behavior genetics: Definition. Term. portion of the cerebral cortex lying at the top of the head ​and toward the rear; receives sensory input for touch and body position. These waves are measured by electrodes place on the scalp, Definition: a series of X-ray photographs taken from different angles and combined by computer into a composite representation of a slice through the body, Definition: a visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task, Definition: a technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue. portion of the cerebral cortex lying roughly above the ears; includes the auditory areas, each receiving information primarily from the opposite ear. Definition: a star-shaped glial cell of the central nervous system. personality changed, Definition: leading psychologist on split-brain patients/studies. Typically, a lesion involves an abnormal structural change to a tissue. (See also Evaluation of the Dermatologic Patient andDiagnostic Tests for Skin Disorders.)
