| tissue destruction. It can occur naturally or experimentally by the caused distruction/remove of brain tissues | ||
| 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. | ||
| a series of x-ray photographs taken from different angles and combined by computer into a composite representaion of a slice through the body. Aslo called a CAT scan | ||
| 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 that distinguish among different types of soft tissues; allows us to see structures within the brain. | ||
| the oldest part and central core of brain. AKA reticular formation, or reticular activating system. In charge of automatic survival functions | ||
| The base of the brainstem. responsible for breathing and circulation. (heart beat) | ||
| Responisble for arousal, filters sensory information | ||
| sleep and arousal | ||
| the brains 'sensory switch board' located at top of brainstem; directs messages to the sensory receiving areas in the cortex | ||
| "little brain" In charge of muscle movement, balance, and coordination. | ||
| A system of neural structures at the border of brainstem. Associated with emotions like fear, agression, and drives such as those for food and sex. Includes the Hippocampus, Amygdala and hypothalamus. | ||
| neural clusters that are components of the limbic system and are linked to emotion. (fear & aggression) | ||
| a neural structure lying below the thalamus. directs (eating, drinking, body temperature), governs the endocrine system via pituitary, linked to emotion and "reward center" | ||
| Limbic system (emotion), processes memory | ||
| Fabric of interconnected neuron cells. Higher order thinking. Takes meaning and puts it to focus. | ||
| Cells in the nervous system that support, nourish, and protect neurons. | ||
| the portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movements (motor cortex) and in making plans and judgements. | ||
| The portion of the cerebral cortex lying at the top of the head and toward the rear; includes the sensory cortex (touch / feeling). | ||
| the portion of the cerebral cortex lying at the back of the head; includes the visual areas, which receive visual info from the opposite visual feild. | ||
| The portion of the cerebral cortex lying roughyl above the ears; includes the auditory areas, each of which revieves aditory info primarily from the opposite end. | ||
| an area at the rear of the frontal lobes that controls voluntary movements. | ||
| Areas of the cerebral cortex that are not invoved in primary motor or sensory funtions; they are involved in higher mental funtions such as learning, remebering, thinking and speaking. | ||
| the area at the front of the parietal lobes that registers and processes body sensations. | ||
| impairment of language, usually caused by Left Hemisphere damage to Brocas area or Wernickes. | ||
| controls language expression (speech). Damage creates inability to speak; usually in the right frontal lobe | ||
| Contorls language reception. Damage creates inability to comprehend language; usually in the left temporal lobe | ||
| the brain's capacity for modification, especially during childhood, by reorganizing after damage or by building new pathways based on experience | ||
| formation of new neurons | ||
| Shares info back and forth; Connects the two hemispheres of the brain and carries messages between them. | ||
| A condition in which the two hemispheres of the brain are isolated by cutting the connecting fibers (corpus callosum) between them. | ||
| our awareness of ourselves and our environment. | ||
| the study of how people perceive, remember, think, speak, and solve problems | ||
| Simultaneously processing on separate conscious and unconscious tracks | ||
| discovered area in the brain (named for him) in the left frontal lobe responsible for language production | ||
| railroad worker who survived a severe brain injury that dramatically changed his personality and behavior; case played a role in the development of the understanding of the localization of brain function | ||
| 1939-present; Field: cognition (neuroscience); Studied of the neural basis of mind with primary responsibility for initiating human split-brain research. In his subsequent work he has made important advances in our understanding of functional lateralization in the brain and how the cerebral hemispheres communicate with one another. | ||
| scientist who won a Nobel Prize for work with split brain patients | ||
| "Wernicke's area"; discovered area of left temporal lobe that involved language understanding: person damaged in this area uses correct words but they do not make sense | ||
| Technique for revealing bloodflow and, therefore, brain activity by comparing successive MRI scans, fMRI scans show brain function |
