Brain research, localisation and anomalies.

	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
