Abstracts Lectures and Seminars from NETT members
Name Steve Coombes Title Mathematical Neuroscience (Lecture)
Name Wolfram Erlhagen Title Applications of Dynamic Field Theory in Robotics (Lecture) Abstract In recent years, there has been an increased interest by part of the robotics community in using the theoretical framework of Dynamic Neural Fields to develop neuro-inspired control architectures. I will discuss how we apply the basic processing principles of DNFs to endow autonomous robots with cognitive capacities like working memory, decision making and prediction. I will illustrate the approach using examples from robot navigation and human-robot interactions.

NETT Fellows’ Talks
Name Romain Caze Title The role of dendritic non-linearities in single neuron computation (Seminar) Abstract Experiment has demonstrated that summation of excitatory post-synaptic protientials (EPSPs) in dendrites is non-linear. The sum of multiple EPSPs can be larger than their arithmetic sum, a superlinear summation due to the opening of voltage-gated channels and similar to somatic spiking. The so-called dendritic spike. The sum of multiple of EPSPs can also be smaller than their arithmetic sum, because the synaptic current necessarily saturates at some point. While these mechanisms are well-explained by biophysical models the impact of dendritic spikes on computation remains a matter of debate. This is because dendritic spikes may fail to make the neuron spike; similarly, dendritic saturations are sometime presented as a glitch which should be corrected by dendritic spikes. I will provide solid arguments against this claim and show that dendritic saturations as well as dendritic spikes enhance single neuron computation, even when they cannot directly make the neuron fire. To explore the computational impact of dendritic spikes and saturations, I am using a binary neuron model in conjunction with Boolean algebra. I demonstrate using these tools that a single dendritic non-linearity, either spiking or saturating, combined with somatic non-linearity, enables a neuron to compute linearly non-separable Boolean functions (lnBfs). These functions are impossible to compute when summation is linear and the exclusive OR is a famous example of lnBfs. Importantly, the implementation of these functions does not require the dendritic non-linearity to make the neuron spike. Next, I show that reduced and realistic biophysical models of the neuron are capable of computing lnBfs. Within these models and contrary to the binary model, the dendritic and somatic non-linearity are tightly coupled. Yet we show that these neuron models are capable of linearly non-separable computations.

Name Peter Dayan
Title Competition and Cooperation between Model-based and Model-free decisions
Abstract Substantial recent work has explored multiple mechanisms of decision-making in humans and other animals. Functionally and anatomically distinct modules have been identified, and their individual properties have been examined using intricate behavioural and neural tools. I will discuss the background of these studies, and describe a number of recent experiments that have cast a stronger, albeit more confusing, light on the interactions between these mechanisms. I will also talk about other related dichotomies of control.
Name Steve Furber
Title Biologically-Inspired Massively-Parallel Computing
Abstract The SpiNNaker project is developing a massively-parallel computer, ultimately to incorporate over a million ARM processor cores, optimised for modelling large-scale systems of spiking neurons in biological real time. It offers a generic fabric for research both into the operating principles of brains and into engineered applications of neural networks, for example in neurorobotics.
Name Michele Giugliano Title Introduction to NAMASEN
Abstract NAMASEN is an initial training network under the FP7 Marie-Curie actions, starting in October 2011. It deals with Neuroelectronics and Nanotechnology, as a ground towards a Multidisciplinary Approach for the Science and Engineering of Neuronal Networks. NAMASEN targets both technological and scientific priorities, such as the development of novel multi-electrode arrays and advanced interfaces that functionally interact with neurons and networks. NAMASEN investigates neuro-electronic hybrids as devices able to undergo a functional and anatomical reconfiguration, on the basis of the activity-dependent plasticity and rewiring properties of neurons, under some control by the experimenter.
Name Andrew Jackson
Title Tools for the brain: Using neural interfaces to restore motor function
Abstract Brain-Machine Interfaces (BMIs) decode electrical activity directly from the nervous system to provide new communication channels for paralysed patients to interact with the environment. However, despite technological advances, the quality of 'brain control' has yet to match the speed, accuracy and efficiency of natural movements. Most current interfaces use a 'biomimetic' approach to decode motoric information, despite profound differences in biomechanical and sensory properties of artificial effectors. In this talk I will argue that BMIs should instead be conceived as abstract tools offering new sensorimotor affordances that the brain must learn to exploit. Understanding the mechanisms by which abstract sensorimotor skills are acquired, and the limits of motor cortical flexibility, will be essential for developing neural interfaces that are compatible with the computational architecture of the motor system.

University Park Talks on Thursday 18 April will take place on the main University Park campus of the University of Nottingham. The
main talks will be in Keighton Auditorium (56 on the map below). The management meeting will be held in Room A17
which is within the Mathematical Sciences Building next door (20 on the map).
NETT Induction Workshop 2013 15
Local Info Buses The indigo bus run by Trent Barton goes every few minutes from Broadmarsh Bus Station (a few minutes’ walk from
Jury’s Inn) – take the stop outside the Queen’s Medical Centre (QMC) which is just outside University Park campus.
https://www.trentbarton.co.uk/services/indigo/maps-and-times (all routes go past the University).
Alternatively, from Canal Street (outside of Broadmarsh Bus Station) you can catch Nottingham City Transport (NCT)
buses numbers 13 or 14 straight to University Park campus (the 13 goes right through the middle of campus).
http://www.nctx.co.uk/Buses/13 or http://www.nctx.co.uk/Buses/14/.
Both options are £1.70 for a single ticket. The NCT buses do not issue change.
The Skylink runs from Broadmarsh Bus Station to East Midlands Airport 24 hours a day
http://www.eastmidlandsairport.com/emaweb.nsf/Content/SkyLinkNottingham. Tickets are £5.
Trams ‘NET’ trams connect the Railway Station to the City Centre but from there only travel North and do not connect at
present to the University. http://www.thetram.net/
Single tickets (off-peak) are £1.90.
Taxis The largest taxi provider in Nottingham is D&G. These are used by the University and well-trusted.
http://www.dgcars.co.uk/ You will need to book on 0115 9500 500 or 0115 9607 607.
The only taxis that can be approached in the street are the large (usually dark green) taxis with the light on top –
similar to the London taxis. There are taxi ranks around the City, including outside Broadmarsh Bus Station, around
the Railway Station and at numerous places in the Centre.
It will typically cost around £8 for a single journey between the city centre and the University.
Local sites of interest Nottingham Castle
Hard to miss. The original castle was destroyed but still interesting.
http://www.nottinghamcity.gov.uk/index.aspx?articleid=1262. Close by is ‘Ye Olde Trip to Jerusalem’ which is
supposedly the oldest pub in England (dates back to 1189).
Nottingham Caves
Bizarrely you get to these from within Broadmarsh shopping centre! http://www.cityofcaves.com/
Galleries of Justice
In the Lace Market area of the City. http://www.galleriesofjustice.org.uk/
Wollaton Park
Right next to the University, free to enter and also where the latest Batman film was shot (recognise the Hall?). http://www.nottinghamcity.gov.uk/index.aspx?articleid=2915
Many other things are in or around Nottingham. There’s also the theatres, ice centre and arena, football grounds,
Trent Bridge cricket ground, several cinemas, etc. http://www.nottinghamcity.gov.uk/index.aspx?articleid=98
