Module description

Analysing large complex data sets is increasingly common within biomedical science specialisms such as neuroscience. To extract meaningful information from such data sets, scientists often use computer programming languages to create bespoke analysis routines. For example, modern recording techniques allow neuroscientists to record the activity of hundreds of neurons at once and the only way to fully understand and integrate these complex data sets is to write specifically tailored computer code to extract relevant information.

In this practical module, we will introduce you to Matlab, a programme commonly used across the medical sciences for carrying out analyses of complex data sets. Most of the contact time in this module will consist of computer lab workshops, where you will learn the fundamentals of writing Matlab code. Once you have grasped these underpinning skills, you will learn how to apply these to specific analytical problems  in medical science and neuroscience research.

Importantly, we assume NO prior knowledge or skills in computer coding: we will be teaching these ‘from the ground up’. Matlab will be provided in the computer labs and is available to download free-of-charge for your personal computer. This is an optional module for BSc Neuroscience, Medical Sciences and Sport & Exercise Medical Sciences. It is not suitable for students who have already taken other university modules in computer coding.  Admission from non-Clinical and Biomedical Sciences-degree programmes is at the discretion of the module lead.

Module aims - intentions of the module

The overall aim of this module is to develop some of the fundamental skills required to analyse and model complex data sets using a straightforward programming language.

You will learn basic practical coding skills in a package commonly used in Medical Sciences: Matlab.

To introduce some areas of  research where computer coding-based analysis  is required, we will focus on specific case studies in the following areas:

  • Data analysis and methods in research
  • Electrophysiology in neuroscience
  • Image analysis and processing

Syllabus plan

Whilst the module’s precise content may vary from year to year, an example of an overall structure is as follows:

We will begin the module with an introduction to fundamental coding skills using Matlab. Later in the module we will introduce some biomedical data analysis and modelling problems which can be addressed using these programming skills. Each of these areas are explored to introduce different analytical and coding skills.

Section 1: Introduction to coding in general and Matlab

Topics may include: Variable types; arrays and matrices; arithmetic in Matlab; indexing; built-in functions; plotting data; algorithms and pseudo-code; scripts and functions; annotating code with comments

Section 2: Data analysis in Matlab

Topics may include: statistical methods, structs and tables in Matlab, variables correlation, ttest and ANOVA

Section 3: Electrophysiology

Topics may include: sampling theory, measuring peaks; batch processing; filtering.

Section 4: Image analysis

Topics may include: images as matrices; sampling theory; identifying regions of interest; measuring; averaging and filtering; images over time – movies.
