Exam 2: Cognitive Neuroscience

Brain imaging has made it possible to

Action potentials occur in the

What is a key difference between dendrites and axons?

When the axon is at rest, the inside of the neuron has a charge that is 70 millivolts more negative than the outside. This difference will continue as long as

Recording from single neurons in the brain has shown that neurons responding to specific types of stimuli are often clustered in specific areas. These results support the idea of

Groups of interconnected neurons are referred to as

Describe how neurons communicate. Mention the key components of the neurons that are involved. Explain the process whereby the electrical signal (the information) is transferred from one neuron to another.

Edgar Adrian studied the relationship between nerve firing and sensory experience by measuring how the firing of a neuron from a receptor in the skin changed as he applied more pressure to the skin. He found that

You are walking down the street and see a nice car drive by. You notice its color, movement, and shape. All of these features are processed

Josiah is trying to speak to his wife, but his speech is very slow and labored, often with jumbled sentence structure. Josiah may have damage to which area of the brain?

Why is it easier to study brain tissue from newborn animals than brain tissue from adults?

The value that stays the same as long as there are no signals in the neuron is known as

Which of the following statements is the most accurate with regard to specificity coding?

Why are memories represented in the brain differently than sensory stimuli? Give an example comparing how the brain would process a visual stimulus and a memory, and explain your reasoning.

Barbara has recently been diagnosed with abdominal cancer. Her oncologist wants to determine the best treatment method to eliminate the tumors. Her gastroenterologist is focused on relieving her symptoms and restoring normal digestive functioning. Barbara's psychologist works to help minimize her anxiety and keep her spirits up. The fact that these doctors are considering Barbara's situation with different goals and from different perspectives is similar to the idea of __________ presented in your textbook.

Which parts of neurons are also known as a "nerve fiber"?

Which of the following statements best describes how neurons communicate with one another?

Which of the following is consistent with the idea of localization of function?

Paul Broca's and Carl Wernicke's research provided early evidence for
