Studying the Damaged Brain

Question 1

Define

Answer 1

Any structural damage to white or grey matter

Question 2

Define

Neoplasms

Answer 2

Tumors, growths that do not have a functional purpose

Question 3

What are the

Three Main Types of Tumors

Answer 3

1. Gliomas
2. Meningiomas
3. Metastatic

Question 4

Define

Gliomas

Answer 4

Abnormal reproduction of glial cells

Question 5

Define

Meningiomas

Answer 5

Originate in the meninges, the protective membranes around the brain

Question 6

Define

Metastatic

Answer 6

Originate outside the brain, e.g. breast cancer or
other malignant tissue travels to the brain

Question 7

Angiography

Answer 7

• To evaluate circulatory system and diagnose disruptions.
• Dye is injected into vertebral or carotid artery, then X-rayed.

Question 8

Question 9

Why is brain damage due to TBI usually more severe in the front?

Answer 9

There are sharp edges inside the skull in the orbitofrontal region

Question 10

Define

Single Dissociations

Answer 10

• requires a minimum of 2 groups & 2 tasks
• when groups differ in performance on one task, but not the other
• provides weak evidence for functional specialization because the 2 tasks could be different w/r/t group sensitivity

Question 11

Define

Double Dissociations

Answer 11

• requires a minimum of 2 groups and 2 tasks
• when one group is impaired on one task and the other group is impaired on the other task
• when one experimental manipulation changes activation in one region and a different manipulation produces changes in a different region
• strong evidence that performance differences reflect actual group differences
