Ch 2 test Flashcards
The neuron fiber that passes messages through its branches to other neurons or to muscle and glands is the ____.
Axon
The tiny space between the axon of one neuron and the dendrite or cell body of another is called the
Synaptic gap
Regarding a neuron response to stimulation, the intensity of the stimulus determines
Whether or not an impulse is generated
In a sending neuron, when an action potential reaches an axon terminal, the impulse triggers the release of chemical messengers called
Neurotransmitters
Endorphins are released in the brain in response to
Pain or vigorous exercise
The autonomic nervous system controls internal functions, such as heart rate and glandular activity. The word autonomic means

The lower brain structure the governs arousal is the
Reticular formation
The part of the brain the coordinates voluntary movement and balance is the _______.
Cerebellum
Two parts of the limbic system are the amygdala and the
Hippocampus
A cats ferocious response to electrical brain stimulation would lead you to supposed the electrode had touched the ______.
Amygdala
The neural structure that most directly regulates eating , drinking, and body temperature is the
Hypothalamus
The initial reward center discovered by olde and Milner was located in the ______.
Hypothalamus
If neurosurgeon stimulated your right motor cortex, you would most likely
Move your left leg
How do differ neural networks communicate with one another to let you respond when a friend greets you at a party
The visual cortex is a neural network of sensory neurons connected via interneurons to other neural network, including auditory networks. This allows you to integrate visual and auditory information to Respond when a friend you recognize greets you at a party
Which of the following body regions has the greatest representation in the somatosensory cortex
Lips
Judging and planning are enabled by the _______ lobes.
Frontal
What would be like to talk on the phone if you didn’t have temporal lobe association area? What would you hear? What would you understand?
You would hear sounds? But without the temporal lob association areas you would be unable to make sense of what you are hearing
The uncommitted areas that make up about three fourths of the cerebral cortex are called ____ _____.
Association areas
Plasticity is especially evident in the brain of
Young children
An experimenter flashes the word HERON across the visual field of a. Man whose corpus callosum has been severed, her is transmitted to his right hemisphere and on to his left hemisphere. When asked to indicate what he saw, the man says he saw ______ but points to _______
On; her
Studies of people with split brains and brain scans of those with undivided brains indicate that the left hemisphere excels in
Processing language
Damage to the brain right hemisphere is most likely to reduce a persons ability to
Make inferences
Failure to see visible objects because our attentions is occupied elsewhere is called ______ _______.
Inattentional blindness
Inattentional blindness and change blindness are forms of _____ attention

With narcolepsy the person periodically falls directly into sleep, sometimes R.E.M. Sleep with no warning; With sleep apnea, the person repeatedly awakens during the night.
In interpreting dreams, Freud was most interested in their
Lantent content, or hidden meaning
What is neural activation theory of dreaming
The neural activation theory suggests that drama are the brains attempts to make sense of random neural activity

R.E.M. Rebound
