Cognitive Psychology Ch 2

Action potentials occur in the

axon

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

he neuron is at rest

Which organ is unique in that it appears to be static tissue?

Brain

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?

Broca's area

Information processing model

What is a key difference between dendrites and axons?

One send information and the other receives information

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

a chemical process takes place in the synapse

The key structural components of neurons are

cell body, dendrites, axon

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

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

localization of function

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

neurotransmitter

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

prosopagnosia

If the intensity of a stimulus that is presented to a touch receptor is increased, this tends to increase the __________ in the receptor's axon.

rate of nerve firing

Which part of the nervous system picks up information from the outside environment?

receptors

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

resting potential

The brain asymmetry demonstration in your CogLab experiment predicts that right handed participants will have a higher hit rate for words shown in the right visual field...

than in the left visual field

A synapse is

the gap that separates two different neurons
