Exam 2: Cognitive Neuroscience

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

The occipital lobe is

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

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

The neuron doctrine is

In a procedure called diffusor tensor imaging (DTI),the way in whichdiffuse(s)along the length of a nerve fiber is measured to determine how different nerves communicate with each other.

Brain imaging has made it possible to

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 thelobe.

The temporal lobe is

Recordings from single neurons are conducted using which of these pieces of equipment?

Describe three physiological techniques for investigating human cognition.What can each technique tell us about the brain and human cognition? Also,give at least one limitation of each of the three techniques.

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

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

Explain how action potentials change in response to stimulus intensity.Use an example from one's visual system to illustrate this process.

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

Define both localization of function and distributed representation.Discuss whether these are opposing or complementary concepts.

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

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

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

Neurons that respond to specific qualities (e.g. ,such as orientation,movement,and length)that make up objects are called
