Cognitive Psychology Chapter 2

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

prosopagnosia

When recording from a single neuron, stimulus intensity is represented by the

firing rate of the action potentials.

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

the neuron is at rest.

Groups of interconnected neurons are referred to as

neural circuits.

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

Arteries

What is a key difference between dendrites and axons?

One sends information and the other receives information.

Sarah has experienced brain damage making it difficult for her to understand spatial layout. Which area of her brain has most likely sustained damage?

Parahippocampal place area (PPA)

The key structural components of neurons are the

cell body, dendrites, and axons.

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.

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.
