APHY 201 CHAPTER 8 CONNECT Exam Questions with Correct Answers
Question 1:
Increased states of alertness are generally indicated on an electroencephalogram plot by
increases in of the waveform.
Answer:
....frequency
The synchronization of cortical neurons that are recorded as waves on an
electroencephalograram is thought thought to originate as synchronized firing of neurons in the
brain structure called the -
Question 2:
Compared to imaging techniques such as positron emission tomography (PET) and magnetic
resonance imaging (MRI), the electroencephalogram (EEG) has much
spatial resolution which makes it far greater; inferior
lesser; inferior
Answer:
....thalamus
for detecting and localizing brain areas damaged by tumors, blood clots, or hemorrhage. lesser;
superior
Question 3:
greater; superior
Most of the electrical signals recorded in an EEG come from the cells of the cortex. -
Answer:
....lesser; inferior
