Thalamus

To demonstrate that brain stimulation can make a rat violently aggressive, a neuroscientist should electrically stimulate the rat's

amygdala

Which neural center in the limbic system plays a central role in emotions such as aggression and fear?

amygdala

In which brain structure are nerves from the left side of the brain routed to the right side of the body?

brainstem

The reticular formation is located in the

brainstem

We are usually least consciously aware of the processes and functions of which brain structure?

Ellen volunteers during her AP psychology class to try to balance a yardstick on her two fingers. While her eyes are open, she finds the task quite easy. However, when she closes her eyes, she finds the same task almost impossible. Which brain region relies on visual information in coordinating our voluntary movements?

cerebellum

Which of the following is the component of the limbic system that plays an essential role in the processing of new memories?

cerebellum

The "little brain" attached to the rear of the brainstem is called the

cerebellum.

A brain lesion refers to ________ of brain tissue.

destruction

Animal research has revealed a general reward system that triggers the release of the neurotransmitter

dopamine.

To identify which specific brain areas are most active during a particular mental task, researchers would be most likely to make use of a(n)

fMRI

In creating more effective treatments for pain, researchers would use which of the following techniques for identifying regions of the brain that handle pain?

functional MRI (fMRI)

Thinking about sex (in your brain's cerebral cortex) can stimulate a region of the limbic system to secrete hormones. These hormones trigger the pituitary gland to influence hormones released by other glands in the body. Which brain region influences the endocrine system?

hypothalamus

Olds and Milner located reward centers in the brain structure known as the

hypothalamus.

The brain structure that provides a major link between the nervous system and the endocrine system is the

hypothalamus.

The secretions of the pituitary gland are most directly regulated by the

hypothalamus.

Severing a cat's reticular formation from higher brain regions causes the cat to

lapse into a coma.

less aggressive

The neural system located at the border between the brainstem and the cerebral hemispheres is known as the

limbic system.

thalamus

Your ability to experience physical sensations is most likely to be disrupted by damage to your

thalamus.
