Exam 9: Brain and Behavior: Brain Research

In order to detect the electrical activity of a single neuron,a scientist would most likely use

Haier and his associates found that the brains of people who perform well on mental tests consume less energy than those who perform poorly on these tests.

Psychiatrist Daniel Langleben and his colleagues have used a new brain technique to tell if a person is lying,with the front of the brain being more active when a person is lying rather than telling the truth.This technology is the

Research using PET scans of human brains indicates that

Which of the following are not direct tests of the brain,but are subtle outward behavioral signs of nervous system dysfunction that have been used to diagnose problems ranging from childhood learning disorders to psychosis?

Subtle behavioral signs of nervous system dysfunction,including clumsiness,an awkward gait,poor hand-eye coordination,and other perceptual and motor problems,are referred to as _______.

A device that detects,amplifies,and records electrical activity in the brain is called

Dr.Kahn is able to detect the electrical activity of a single neuron by using the tip of an extremely thin glass tube filled with a salty fluid,which is known as an ablation tube.

If damage to a particular part of the brain consistently leads to a particular loss of function,then we say that the function is

A psychiatrist does a lengthy and thorough examination of a patient in a hospital.This patient was the victim of a car accident,in which a pen that was lying on the dashboard actually pierced her skull and her brain.The psychiatrist performs physical examinations,interviews with the patient and family members,and closely observes her behavior.This technique is known as a(n)
