Describe the spatial and temporal resolution of EEG and MEG

Give some invasive variation of EEG, and describe the method of recording and spatial resolution for each.

what are the major limitations of Electrocorticography (ECoG). When might it be used? Give a paper which has reveiwed ECoG in humans

Give a paper, and the benefits it describes linked with Electrocorticography (ECoG). What is its suggested use?

Describe local field potentials

What is the difference between EEG and MEG signals compared to signals from CT, PET and fMRI

Give an example of a paper which combined EEG with fMRI. Summaries what they did/found

Describe how the structure of the brain might affect an EEG signal

Why does EEG have a poor spatial resolution?

What are we actually measuring with an EEG? what implications does this have for the signal?

What is meant by synchronised firing of neurons? Why is this important for and EEG signal?

Describe the difference between open field organisation and closed field organisation?

Describe how the placement of the electrodes might make a small difference to the signal we record? Why is this only a small difference?

what is an event related potential/event related field?

How can an event related potential be used?

What is device used to measure MEG ? What does it actually measure?

What orientation do neurones have to lie in relation to the SQUID during MEG for a signal to be picked up. Why is this?

What does a SQUID use to detect magnetic fields?

Why do we need to take 100s of trials when looking at an event related potential?

Why would combining EEG with another technique be useful?

What is a lateralized readiness potential?

with regards to the lateralized readiness potential, what happens to the signal before we initiate movement? what can affect this?

Describe what the Libet clock was designed to do?

What were the results from the Libets clock?

What is frequency analysis?

what type of frequency is associated with object perception

Give a study which looked at increases in gamma activity, and give what was done

What is the binding problem?

Describe a study which shows gamma waves contribute to object perception using infants.

What is beta activity associated with?

What disease is linked with higher beta activity? What is the treatment to reduce this activity?
