Introduction to Neuroimaging Methods

Lectures and Workshops

Lectures and workshops will take place on Wednesdays, 14.30, in the CBU West Wing Seminar Room (unless stated otherwise, please check below). Workshops usually take about 2 hours, lectures may be shorter.

Details will be announced before individual events via this mailing list: http://lists.mrc-cbu.cam.ac.uk/mailman/listinfo/skillstraining (Non-CBU people can subscribe by sending an e-mail to skillstraining-subscribe (at) mrc-cbu (dot) cam (dot) ac (dot) uk).

We expect attendees to have basic skills in scientific computing and programming, e.g. at the level taught in our previous workshops. It might help to refresh your memories a little bit.

Look here for other training opportunities in and around Cambridge.

Please contact OlafHauk with questions and feedback.

14.30

Multivariate fMRI Analysis I PDF

Marieke Mur

Lecture + Workshop

This workshop introduces linear classification, one of the most popular forms of multivoxel pattern analysis. We will give an overview of the most commonly used linear classifiers, and list the steps that are needed to implement a classification analysis. The workshop will include a hands-on matlab session, during which we'll go through example code that performs linear classification on an fMRI data set.

Multivariate fMRI Analysis II PDF

Marieke Mur

Lecture + Workshop

This workshop introduces representational similarity analysis (RSA), a more recent form of multivoxel pattern analysis which has gained popularity over the last few years. We will give an overview of the origin of RSA and how it relates to linear classification, and list the steps that are needed to implement RSA. The workshop will include a hands-on matlab session, during which we'll analyse the same fMRI data as last week, but this time using RSA.

Multimodal Imaging

Rik Henson

Lecture

This lecture will describe possible generative models that can be used to integrate data from EEG, MEG and fMRI

May 16 (Tuesday !!!)

13.00

Connectivity with EEG/MEG and fMRI

Rik Henson

Lecture

This lecture will introduce concepts of functional and effective connectivity, briefly describe effective connectivity in fMRI (eg dynamic causal modelling) and then expand on the larger range of methods available for measuring connectivity with EEG/MEG.

May 24

14.30

Diffusion MRI I

Marta Correia

Lecture + Workshop

This workshop will cover the basic principles of diffusion MRI acquisition and data analysis. It will include a practical component covering pre-processing of diffusion MRI data, model fitting, group analysis of diffusion parameters and tractography.

Diffusion MRI II

Marta Correia

Lecture + Workshop

In this week’s workshop we will continue the hands on session for pre-processing of diffusion MRI data and introduce methods for group analyses. We will also cover more advanced diffusion MRI methods, including tractography and probabilistic modelling.

MRI Physics 1: Introduction to MRI Physics

Marta Correia

Lecture (~1.5h)

This talk will cover the basic principles of MRI physics for beginners, including nuclear spins and net magnetization, excitation and relaxation mechanisms, slice selective gradients, frequency and phase encoding, image formation and k-space.

Jan 30 (Monday!!)

MRI Physics 2:The BOLD Signal and Common Artefacts

Marta Correia

Lecture

This talk is aimed at fMRI beginners and will be divided into two parts. Firstly, I will talk about the biophysics of fMRI and the basic mechanism behind BOLD contrast. In the second half, I will discuss common image artefacts and ways to work around them.

fMRI Analysis 1: fMRI Pre-Processing (workshop materials)

Johan Carlin

Lecture + Workshop

We will cover basic preprocessing of fMRI data, and some useful diagnostic visualisations to help spot problems.

fMRI Analysis 2: Single subject analysis using GLM (workshop materials)

Johan Carlin

Lecture + Workshop

This workshop covers the basic principles of single-subject design focusing on how it is implemented in SPM. We will also discuss how to design efficient fMRI experiments.

fMRI Analysis 3: Group analysis and statistical inference (workshop materials)

Johan Carlin

Lecture + Workshop

After a short recap of the GLM, which also is the basis of group analysis, we will review some example designs. We will focus especially on statistical inference and multiple comparisons correction.

Brain stimulation PDF

Benedikt Zöfel

Lecture (45 min approx.)

This talk will provide an introduction to brain stimulation methods, with a focus on transcranial magnetic stimulation (TMS) and transcranial electrical stimulation (tES). I will cover the principles of these techniques, the physiological basis of the effects, the different protocols used, and examples of how brain stimulation can be used as an experimental and therapeutic tool.
