17
Q

What does the fore brain control?

A

18
Q

What are rabies?

A

Virus transferred in saliva to CNS to hippocampus

Causes aggression

19
Q

What is a frontal lobotomy?

A

Inserting sharp tool through eye socket, alleviate aggression violence
No anaesthesia as no nociceptors in frontal lobe

20
Q

Injury in the amygdala can cause what?

A

Change in aggression

21
Q

What is epilepsy?

A

Spontaneous activity in hippocampus neurons. Causes seizures - saliva, muscle convulsions, rolling eyes. Caused by genetics/trauma/infections. Treated with sedatives/tranquilizers

22
Q

What it is the reticular formation?

A

Part of brain stem, responsible for regulating life functions
(Lesion = death)

23
Q

What is the ascending reticular activating system? What is the clinical signifcance?
