tissue destruction; a brain lesion is a naturally or experimentally caused destruction of brain tissue.
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.
CT (computed tomography)
a series of X-rays photographs taken from different angles and combined by computer into a composite representation of a slice through the body. Also called a CAT scan.
APP- The CAT scan is basically like a look inside the body (just skeletons) that give you a better look.
PET (Positron emission tomography)
a visual display on brain activity that detects where a radioactive form of glucose goes while the brain performs a give task.
APP- if I'm a counselor and a patient just randomly have outbursts unrelated to environment, I might make the patient have a PET scan.
MRI (Magnetic resonance imaging)
a technique that uses magnetic fields and radio waves to produce computer-generated images of soft tissue. MRI scans. MRI scans show brain anatomy.
APP- If someone was to have something in their head (like when my dad had cancer) he had to get a MRI to see what exactly was there.
fMRI (functional MRI)
a technique for revealing bloodflow and,therefore, brain activity by comparing successive MRI scans. fMRI scans show brain function.
APP- The fMRI basically just shows how a person's brain is working.
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.
APP- The Brainstem is like an UPS man. It controls the flow of messages. For example, it'll control blood temperature.
the base of the brainstem; controls heartbeat and breathing.
APP- When I was working out, I noticed that my medulla was the actual thing controlling what I needed at the time.
a nerve network in the brainstem that plays an important role in controlling arousal.
APP- The Reticular Formation helps with sleeping habits because it controls the cycle.
the brain's sensory switchboard, located on the of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla.
APP- The Thalamus is like someone who answers the phone but always relay messages to a more important area.
the "little brain" at the rear of the brainstem; functions include processing sensory input and coordinating movement output and balance.
APP- Cerebellum is like a small important person (VP) that makes sensory and move my balance.
doughnut-shaped neural system (including hipppus amygdala, and hypothalamus) located below the cerebral hemispheres; associated with emotions and drives.
APP- The Limbic System is what connects emotions and drives like a bridge.
two lima bean-sized neural clusters in the limbic system;linked to emotions.
APP- When you are sad, Amygdala is used in the limbic systems.
the intricate fabric of interconnected neural cells covering the cerebral hemispheres; the body's ultimate control and information-processing center.
APP- The Cerebral Cortex is like a blanket that covers the important stuff.
Glial Cells (glia)
cells in the nervous system that support, nourish, and protects neurons.
APP- The Glial Cells (glia) is like the mother cells. It takes care of the neurons.
portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movement and in making plans and judgement.
APP- The Frontal Lobes are like the spot in your brain that just helps you with making decisions and helping you say them.
portion of the cerebral cortex lying at the top of the head and toward the rear; reviews sensory input for touch and body position.
APP- The Parietal Lobes will tell someone that food is too hot so they should blow it.
portion of the cerebral cortex lying at the back of the head;includes areas that receive information from the visual fields.
APP- The Occipital Lobes is like military field in a foreign country that no one really messes with but it still receives information.
portion of the cerebral cortex lying roughly above the ears; including the auditory areas, each receiving information primarily from the opposite ear.
APP- The whole, "in one ear and out the other" is ALMOST true except for the fact that information doesn't go out it just goes to the other ear.
an area at the rear of the frontal lobes that controls voluntary movements.
APP- The Motor Cortex is like an area that cannot be controlled. Like it controls the mind of its own.
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 emotions and reward.
APP- Hypothalamus is like a president. It directs and helps everything.
area at the front of the parietal lobes that registers and processes body touch and movement sensations.
APP- The Sensory Cortex really is everything that makes your body "feel".
areas of the cerebral cortex that are not involved in primary motor or sensory functions;rather , they involve in higher mental functions such as learning, remembering, thinking, and speaking.
APP- The Association Areas are like the AP students in a school. They are on a higher level than the other students.
impairment of language, usually caused by left hemisphere damage either to Broca's areas (impairing speaking) or Wernicke's area (impairing understanding).
APP- Aphasia is like when someone gets in a car accident and forget everything.
controls language expression- and area, usually in the left frontal lobe, that directs the muscle movement involved in speech.
APP- The Broca's Area is what is used when people express what they are trying to say.
controls language reception- part of the brain area involved in language comprehension and expression; usually in the left temporal lobe.
APP- The Wernicke's Area is like the part of the branch that breaks down everything you need to know.
the brain's ability to change, especially during childhood, by reorganizing after damage or by building new pathways based on experience.
APP- Plasticity is like rebuilding after a hurricane (hurricane being your crazy childhood).
the formation of new neurons.
APP- Neurogenesis is just when new neurons come about.
the large bands of neural fibers connecting the two brain hemispheres and carrying messages between them.
APP- Corpus Callosum is like the gossipers in a group that goes relaying messages between everyone.
a condition resulting from sugary that isolates the brain's two hemispheres by cutting fibers (mainly those of the corpus callosum connecting them.
APP- With a split brain, you can put "HEART" in front of someone and the will say they see "ART" but point to "HE".
our awareness of our selves and our environment.
APP- My consciousness told me that at the Salem vs. Rockdale game, I was not safe.
the interdisciplinary study of the brain activity linked with cognition (including perception , thinking, memory, and language.)
APP- Cognitive Neuroscience is the brain activity that gives you the chain between everything that happens with your brain.
the principal that formation is often simultaneously processed on separate conscious and unconscious tracks.
APP- Dual Processing is like thinking that formation is always between opposites.
