Sample Question 1
Which of the following is false?

The probing excitability approach which tests the responsiveness of the motor system during a cognitive task. If the motor cortex is required for a cognitive task then it should already be activated when single-pulse TMS is delivered. The measure of interest is how strongly the motor cortex reacts to the pulse itself and how strongly the body part will move in response to the additional stimulation.

The virtual lesion approach involves repeated TMS (rTMS) which can inhibit functions for a longer period of time.

The paired pulse approach first activates the brain using a sub-threshold stimulation and then interferes with neuronal transmission using a second supra-threshold stimulation and aims to answer the question of how strongly the first stimulation affects the second.

Schizophrenics have an increased Cortical Silencing Period (CSP), meaning that the cooling off period is reduced after excitation and thus there is hyperexcitability and problems with getting rid of muscular activation.

Sample Question 2
Which of the following is incorrect

The Z distribution uses the population SD

The t statistic takes into account both the expected mean and a measure of the standard error of the mean based on the sample

The bottom of the above equation refers to the standard mean of the population

The x value with a hat refers to the sample mean

Sample Question 3
Which of the following is false in relation to EEGs

Great temporal resolution but poor spatial resolution

Can't test causality

Electrode cap signals are amplified and EEG is recorded during experimental stimulation

EEG reflects post-synaptic potentials (voltages that arise when NT bind to receptors of the post-synaptic cell). This causes ion channels to open/close, leading to graded change sin the potential across the membrane.

EEGs pick up the summation of charges

Folding within the brain (gyrus) destroy signals, therefore there is not an accurate representation
