|
Lesion method |
Attempting to relate areas of brain damage to specific cognitive or behavioral deficits. |
|
|
The problem of specificity |
Is the function impaired becaus it is specifically related to the damage area? Or is it impaired because it is difficult? OR would the same function impaired by comparable damage of other parts of the brain? |
|
|
Double dissociation |
A hypothesis testing method in which we can confidently say that if function is affected by lesion in A but not in B AND if function b is impaired by lesion in B but not by A, THEN the two functions are physiologically separable. |
|
|
Wada Test |
also known as the intracarotid sodium amobarbital procedure (ISAP) establishes cerebral language and memory representation of each hemisphere. |
|
|
The "law" of converging operations |
The principle stating that if a hypothesis is supported by evidence from multiple different sources, then the hypothesis is more and more likely to be true |
|
|
Subarachnoid hemorrhage |
is bleeding in the area between the brain and the thin tissues that cover the brain. This area is called the subarachnoid space. |
|
|
Circle of Willis |
system of arteries that sits at the base of the brain |
|
|
Stroke |
Appearance of neurological signs (numbness, loss of control, spasmodic motions) due to interruption of blood flow |
|
|
Infarction |
Tissue destruction due to loss of blood flow |
|
|
Thrombosis |
Clot of plugged blood vessel |
|
|
Embolism |
Clot of plug from an airbubble or blockage from some other point that gets lodged in a smaller vessel |
|
|
TIA, Transient ischemic attack |
Episodic or intermittent depletion of vascular activity |
|
|
Intracranial hemorrhage |
Bleeding from blood vessels typically associated with hypertension |
|
|
Aneurysm |
an excessive localized enlargement of an artery caused by a weakening of the artery wall. |
|
|
Trauma |
Blunt force: Can be localized neurofunctional damage but there is often recovery. |
|
|
Edema |
Swelling in the vicinity of brain damage |
|
|
Name one sign of a seizure |
EEG regularity of signal oscilations |
