Quiz 2 Cognitive Psychology
What is the gap between the end of a neuron's axon and the dendrites or cell body of another neuron known as?
Synapse
A 10-month-old baby is interested in discovering different textures, comparing the touch sensations between a soft blanket and a hard wooden block. Tactile signals such as these are received by the __________ lobe
parietal
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
Which parts of neurons are also known as a "nerve fiber"?
axon
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
Early studies of brain tissue that used staining techniques and microscopes from the 19th century described the "nerve net." These early understandings were in error in the sense that the nerve net was believed to be ___
continuous
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
When recording from a single neuron, stimulus intensity is represented by the _____
firing rate of the action potentials
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
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
Edgar Adrian studied the relationship between nerve firing and sensory experience by measuring how the firing of a neuron from a receptor in the skin changed as he applied more pressure to the skin. He found that _____.
the rate of nerve firing increases as he increased the pressure
