Application of Brain Imaging

What is a brain controlled interface?

Give the two different types of brain control interfaces, and describe each of them.

Describe the general characteristics of a slow cortical potential

Explain how someone might use slow cortical potentials to help with medical conditions

Give the type of EEG potential that would be used to set up communication with a 'locked in' patient.

What is a P300 evoked potential?

Describe the process of how a P300 could be used to interpret a word people are thinking of.

Describe how EEG could be used to look movement related changes in beta activity, and give a paper which supports this and give its findings.

What evidence is there that movements could be controlled using a brain controlled interface?

Give limitations for using EEG for brain control interfaces

EEG has limitations for brain control interfaces, suggest two other techniques which is similar to EEG. Give positives and negatives of each alternative method and studies which assessed these techniques

Describe the Hochberg 2006 study.

What is directional tuning?

Suggest what technique is used for mind reading, and define what mind reading actually is.

Give the principle behind neurofeedback.

Which study showed that brain activity can be modulated by neurofeedback.
