a synapse is (Ans- space between neurons
action potentials occur in the (Ans- axon
When recording from a single neuron, stimulus intensity is represented in a single neuron by the (Ans- firing rate of the action potentials.
Which of the following statements best describes how neurons communicate with one another?(Ans- A chemical process takes place at the synapse.
The occipital lobe is (Ans- the first place in the cerebral cortex where visual information is received.

There are many methods for studying the physiology of the brain.________ is the technique involving subtraction whereby brain activity is compared between baseline and stimulation measurements.(Ans- the structure of individual neurons.
Brain imaging has made it possible to (Ans- determine which areas of the brain are involved in different cognitive processes
Which of the following do PET and fMRI have in common?(Ans- The use of the subtraction technique
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 his (Ans- broca's area
Damage to Wernicke's area is in which lobe of the brain?(Ans- temporal

notice many features of it: its color, movement, shape, location, and so
forth. All of these features are processed (Ans- in different parts of the brain
The layer of neurons that lines the back of the eye is called the (Ans- retina
Neurons that respond to features that make up objects are called (Ans- feature detectors
If kittens are raised in an environment that contains only verticals, you would predict that most of the neurons in their visual cortex would respond best to the visual presentation of a (Ans- picket fence 2 / 3
The idea of a grandmother cell is consistent with (Ans- specificity coding
A grandmother cell responds (Ans- only to a specific stimulus
When conducting an experiment on how stimuli are represented by the firing of neurons, you notice that neurons respond differently to different faces. For example, Arthur's face causes three neurons to fire, with neuron
- responding the most and neuron 3 responding the least. Roger's face
causes the same three neurons to fire, with neuron 1 responding the least and neuron 3 responding the most. Your results support ____ coding.(Ans- distributed
Most cognitive psychologists _____ the notion of a grandmother cell.(Ans- reject
A specific person's face is represented in the nervous system by the firing of (Ans- a group of neurons each responding to a number of different faces.

Which of the following is an experimental procedure used to study how attention affects the processing of competing stimuli?(Ans- Dichotic listening
Dichotic listening occurs when (Ans- different messages are presented to the left and right ears.
