Short Description

This course will introduce students to key issues in brain imaging, namely: mechanisms of generation of EEG-MEG signals, topographical distribution, relation between evoked magnetic fields and electric potentials, relationship to cognition; physical basics of Magnetic Resonance imaging (anatomical images, gradients, RF); basics of functional MRI - blood oxygenation contrast (BOLD, neurophysiological basis, neuronal responses, local field potentials, etc); basics of fMRI experimental design (block design, event related design, adaptation); recent advances in recording and analysing EEG and fMRI signals simultaneously; application of brain imaging to clinical cases; recent advances in understanding the brain-behaviour relationship by non-invasive transcranial brain stimulation

Timetable

2 hours per week

Requirements of Entry

Typically a 2:1 honours degree in psychology or related discipline.

For the MSc Brain Sciences, at least a second class (2:2) honours degree in neuroscience, physiology, psychology or acceptable equivalent(s).

Excluded Courses

None

Assessment

One piece of coursework (100%, 3,500 words). Either a critical review on brain imaging methods with a topic to be chosen from a list of questions or an essay on how the student would adapt their research project to a different imaging technique than they plan to use.

Course Aims

This course will introduce students to the following key issues in brain neuroimaging:

a) The mechanisms of generation, topographical distribution, and analyses of evoked and induced magnetic and electric fields and their relationship to cognition.

b) Physical and physiological basis of structural and functional magnetic resonance imaging.

c) Basics of fMRI experimental design.

d) Clinical applications of imaging techniques.

e) Recent advances in understanding the brain-behaviour relationship by non-invasive brain stimulation.

f) Simultaneous EEG-fMRI recording and analyses.

g) Information processing algorithms in the brain.

Intended Learning Outcomes of Course

Students will be able to:

■ Discuss the capabilities of various brain imaging approaches such as transcranial magnetic stimulation (TMS), transcranial direct and alternating current stimulation (tDCS, tACS), functional magnetic resonance imaging (fMRI), electroencephalography (EEG) and magnetoencephalography (MEG) to advance our understanding of brain function in health and disease.

■ Reflect critically on our current understanding of the physical and physiological principles underlying the measurements obtained in different brain imaging modalities (TMS, tDCS, tACS, fMRI, M/EEG)

■ Critically evaluate the experimental designs typically used with different modalities of brain imaging.

■ For different brain imaging modalities (TMS, tDCS, tACS, fMRI, M/EEG), provide critical evaluation of the steps taken to record, and process the measurement data in light of interpretational confounds.

■ Critically evaluate advantages and limitations of different imaging techniques and how multi-modal approaches might benefit our understanding.

Minimum Requirement for Award of Credits

Students must submit at least 75% by weight of the components (including examinations) of the course's summative assessment.
