Quiz 5 (Psych 049)

Posterior parietal cortex (PPC)

Researchers have identified the following area to be important in making a decision in rodents.

True

T/F: In the experiment that we did in my lab trying to understand Fragile X Syndrome, Fragile X mice take longer to complete the visual discrimination task

increase

A decision variable is influenced by accumulation of evidence. This happens at the level of ______________ in activity of neurons.

vertical lines

In a go/no-go task subjects were told to press the key “A” if they saw vertical lines on the monitor and withhold pressing any key if they saw horizontal lines. If the subjects got a “hit” then it meant that the monitor displayed.

Yes

No/Yes: In a go/no-go task the task requires reporting the presence of a correct stimulus by responding ( for example licking) and reporting the incorrect stimulus by witholding the response.

simple tasks can be implemented in rodents to study decision making similarity conserved brain areas between mice, primates and humans

Why do we use the rodent brain to study decision making

false

T/F: In an experiment, using rodent behavior, researchers tracked the Hits and FAs. They found that both Hits and FAs increased during training. The researchers concluded that the mice had learned well and become experts. Are they correct ?
