Neural Computation 2013-2014
Neural Computation (NC) is a 10 point MSc course of 18 lectures in
the first semester.
(Other students can attend after agreement).
Lectures are Tuesday and Friday: 12.10-13.00, Tuesday and Friday in
LT5 7BSQ. We start on time!
The first lecture will be in week 2
on September 24th 2013.
In this course we study the computations carried out by the nervous
system. Unlike other courses and artificial neural networks, we take
a bottom-up approach. This means that we incorporate data from
neurobiology, simulate certain aspects of it, and try to formulate
theories about the brain.
For whom is this course?
This course will appeal to students who are interested in the basic
principles and 'biological hardware' implementations of the
in human and animals brains.
For whom is it not?
The topics discussed in the course have inspired software solutions
to real-life problems, however, we shall hardly
discuss those. The course has little practical applicability outside
models, small networks, neural codes, models of learning and

Office hours: make an appointment or catch me after the lecture.
No prior biology/neuroscience knowledge is required. I use a small
subset of not very advanced math in the lectures. Keywords: linear differential equations, eigenvectors, Fourier transformations, fixed points.
FMCS lecture notes
can be used as a refresher.
Alternatively, use Google to refresh forgotten maths if needed. If
you are still stuck, use the practicals or office hours to resolve
In the tutorials we use MatLab and NEURON (a special purpose
simulator). No prior experience with either is required, however
MatLab skills are valuable for many courses.
More information on Matlab and how
to make graphs and write reports.
The course will be fully assessed by two reports of practical
assignments which will appear here. The two marks are averaged.
Standard late policies will apply. Also see How to make graphs and write reports.
