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

Specific areas of the brain serve different functions. Neurons in different areas of the brain respond best to different stimuli. Brain areas are specialized for specific functions All are correct

The fusiform face area (FFA) in the brain is often damaged in patients with

prosopagnosia

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 1 responding the most and neuron 3 responding the least. Roger's face causes three different neurons to fire, with neuron 7 responding the least and neuron 9 responding the most. Your results support __________ coding.

sparse

The idea that an object could be represented by the firing of a specialized neuron that responds only to that object is called _____________.

specificity coding

Which substance is released when signals reach the synapse at the end of the axon?

neurotransmitters

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

picket fence

The key structural components of neurons are the

cell body, dendrites, and axons

The study of the physiological basis of cognition is known as

cognitive neuroscience

Brain imaging has made it possible to

determine which areas of the brain are involved in different cognitive processes

The idea that specific cognitive functions activate many areas of the brain is known as

distributed representation.

Neurons that respond to specific qualities of objects, such as orientation, movement, and length, are called

feature detectors.

Groups of interconnected neurons are referred to as

neural circuits

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

A chemical process takes place in the synapse.

Which of the following terms does NOT reflect functional network activity in the brain?

Consistent

What does the principal of neural representation state?

Everything a person experiences is based on representations in the person's nervous system.

Ramon is looking at photos of athletes in a sports magazine. He is focusing on their body parts, particularly their chest and legs. Which part of Ramon's brain is activated by this viewing?

Extrastriate body area (EBA)

In which of the following body parts are neurons NOT present?

arteries

Action potentials occur in the

axon

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

in different parts of the brain

A synapse is

the gap that separates two different neurons
