| refers to the idea that one hemisphere has specialised functions or exerts greater control over a particular function But they work together to coordinate almost all our behaviour |  | |
| Regulates arousal, attention and sleep-wake transitions (wakefulness), behaviour, autonomic functions (such as breathing, heartbeat), motor responses to external stimuli such as walking, other functions such as toileting, eating. |  | |
| It relays sensation, spatial sense and motor signals to the cerebral cortex, along with the regulation of consciousness, sleep and alertness |  | |
| The part of the cebral cortext controls the muscles required for speech & responsible for the production of clear, fluent (articulate) speech |  | |
| This area of the brain is involved in comprehension of speech/language, location of word from memory to enable expression of thought | | |
| Severing of the corpus callosum, done to minimise severity of epliptic fits. | ||
| This condition is caused by damaged to right parietal lobe, victim behaves as if left side of world doesn't exist | ||
| The perception consistently differs from objective reality | ||
| After starting at a moving image for a period of time, then looking at a stationary image, the stationary image appears to move in the opposite direction to the moving image. |  | |
| Is the phenomenon that occurs when a person viewing a visual scene apparently fails to detect changes in the scene. | ||
| is a neurologically-based condition in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway. |  | |
| Describes the condition in which victimes are unable to use lanaguage appropriately whether it be speaking, hearing language or reading language. | ||
| This brain structure provides the bridgeway that enables communicationg between the left & right hemispheres |  | |
| Uses an electrode to deliver a mild (weak) electrical current to a specific area of the brain of a conscious patient in order to initiate or inhibit a response e.g. Movement. This homunculus highlights that proportionally the mouth & hands occupy a greater area than other parts of the body due to their enhanced capability for fine motor motor movements/ sensitivity to external stimuli as confirmed by Penfield and his research on live patients when mapping the cerebral cortex |  | |
| This devices uses an electromagnetic conductor (coil) to induce a weak electric currents using a rapidly changing magnetic field; this can cause activity in specific or general parts of the brain with minimal discomfort, allowing the functioning and interconnections of the brain to be studied. |  | |
| The patient is injected with iodine then a series of Xray's of the brain from different angles (by moving in an arc around the head), these Xray images are processed by a computer to produced a (2 dimensional) cross sectional image (snapshot) of the brain. A computer then combines these images to generate a 2 or 3 dimensional image of the brain |  | |
| This devide uses magnetic fields & radio waves to vibrate atoms in the brain detected by magnetic chamber - images processed by a computer to create A 3D coloured representation of the brain |  | |
| A harmless radioactive substance (usually glucose) is injected into the bloodstream - which results in the scan providing a 'coloured map' of the brain's activity radioactive signals emitted by the tracer (glucose) are tracked and processed by the computer to produce an image of the working brain |  | |
| A radioisotope (tracer) is injected into bloodstream, brain areas that require more oxygenated blood are assumed to be engaged in higher levels of activity. A computer identify these areas based on the high concentration of the radioisotope |  | |
| Detects subtle changes in oxygen levels in blood flow through the brain when completing tasks, by taking numerous pictures of the brain in rapid succession - hence can detect brain changes that occur from moment to moment |  |
