The two main sections of the forebrain are the:

The brain of a person on a heightened state of alertness may exhibit enhanced activity of the endorphins.

Jennifer forgets any new memory formed while she is distracted.Which region of her brain is MOST likely to show impairment?

Use the following to answer questions : Scenario II In pioneering research by Sperry and colleagues,split-brain patients were asked to stare at a dot on a screen centered between their eyes,while words of common objects were projected onto the screen either in their left or right visual fields.Subsequently,patients were asked to reach behind a screen with either their left or right hands and identify the object among other common objects by touch alone. -(Scenario II)Using the procedure described in the scenario above,split-brain patients were simultaneously shown the word key in the left visual field and the word chain in the right visual field.They were then asked to reach behind a screen with their left hand and find the object that was projected onto the screen.Among the objects behind the screen are a key,a small chain,a key chain minus the key that one can typically purchase at novelty stores,and a lock.Which object will the patients select?

Cyrus suffered a stroke and is now blind in the right visual field in each eye.The stroke probably occurred in which cortical lobe?

Which sequence shows the CORRECT order of the firing of a neuron?
