The human brain is perhaps the most complex machine in the universe; in the Computational Modelling Laboratory, we develop computer models of the brain that help us to understand this complexity.
Sometimes, those models help us visualise and analyse the massive raw data from neuroscience experiments in more revealing ways. Other times, our models are designed to mimic or replicate aspects of brain function.
These models can help develop a better understanding of mental health disorders, help make human learning more efficient, and they can inform the development of the next generation of smart machines.

Investigating learning and memory
The Computational Modelling Laboratory Lead, Professor Andy Wills, works on the computational modelling of learning and memory.
He has worked on computer models of amnesia (O’Connell et al., 2016), decision-making (Sambrook et al., 2018), and maintains the catlearn software package – a popular modelling tool with over 14,000 downloads to date (Wills et al., 2017).
He also works on a project concerning the relation between errors and learning, funded by the Economic and Social Research Council.Dr Elsa Fouragnan, Lecturer in Psychology also works on the relation between errors and learning, using sophisticated computer models in her analysis of imaging data on this topic (Fouragnan et al., 2018).
BRIC neuroscience and
High-Performance Computing Centre
Researchers at BRIC are able to process large and complex datasets through the high-speed links to the High Performance Computing Centre (HPCC) at the University of Plymouth.
A collaboration with Dr Antonio Rago, Associate Professor and colleagues in the Faculty of Science and Engineering, supports the processing of complex computational routines for empirical human neuroimaging data analysis and In Silico neural, cognitive and behavioural models.
Other research in this laboratory will be carried out by
Dr Elsa Fouragnan and Professor Roman Borisyuk

Enhancing research through BRIC
The Computational Modelling Laboratory in the BRIC facility will provide Plymouth’s neuroscientists with access to high-performance computing and data storage facilities.
It will also offer a common working space for researchers and postgraduate students with interests in computational neuroscience.
