January 14th - Lecture #2

Question 1

Natural Lesions

Answer 1

• Studying patients with brain injuries to observe how damage to specific areas affects cognitive functions.

Question 2

Experimental Lesions

Answer 2

• Using animal models to create controlled lesions, helping to determine the role of specific brain regions.

Question 3

Transcranial Magnetic Stimulation (TMS)

Answer 3

• Creating temporary, reversible disruptions in brain activity to study the effects on cognitive tasks.

Question 4

ectomy

Answer 4

• Surgical removal of brain tissue to treat medical conditions or alleviate symptoms.

Question 5

Temporal Lobectomy

Answer 5

• The removal of part of the temporal lobe to
  evacuate a hematoma (a collection of blood). This can be done in cases of brain injury or hemorrhages, such as from a traumatic event.

Question 6

Lobotomy

Answer 6

• The functional disconnection of parts of the brain, historically used to treat mental health conditions, though it’s no longer a standard practice.

Question 7

Hemispherectomy

Answer 7

• The removal or disconnection of one hemisphere of the brain, often used as a treatment for severe, intractable epilepsy.
  It can lead to significant changes in cognitive and sensory function depending on the hemisphere involved.
