Future Selves: Career choices of young disabled people
Journal Article
Shah, S., Pascall, G., & Walker, R. Future Selves: Career choices of young disabled people

There is growing recognition that gaining the views of young people is crucial for understanding issues that affect their lives. However, to date, very little is known about the way in which disabled children, make sense of their identities, and crea... Read More about Future Selves: Career choices of young disabled people.

Safety and complexity: the inter-departmental threats to patient safety in the operating department
Journal Article
Waring, J., McDonald, R., & Harrison, S. Safety and complexity: the inter-departmental threats to patient safety in the operating department. Journal of Health Organization and Management, 20(3), https://doi.org/10.1108/14777260610662753

Purpose: Current thinking about ‘patient safety’ emphasises the causal relationship between the work environment and the delivery of clinical care. This research draws on the theory of Normal Accidents to extend this analysis and better understand th...

The importance of different timings of excitatory and inhibitory pathways in neural field models
Journal Article
Laing, C., & Coombes, S. The importance of different timings of excitatory and inhibitory pathways in neural field models

In this paper we consider a neural field model comprised of two distinct populations of neurons, excitatory and inhibitory, for which both the velocities of action potential propagation and the time courses of synaptic processing are different.

Dendritic cable with active spines: a modeling study in the spike-diffuse-spike framework
Journal Article
Timofeeva, Y., Lord, G., & Coombes, S. Dendritic cable with active spines: a modeling study in the spike-diffuse-spike framework. https://doi.org/10.1016/j.neucom.2005.12.045

The spike-diffuse-spike (SDS) model describes a passive dendritic tree with active dendritic spines. Spine-head dynamics is modelled with a simple integrate-and-fire process, whilst communication between spines is mediated by the cable equation. Her...

Waves, bumps, and patterns in neural field theories
Journal Article
Coombes, S. Waves, bumps, and patterns in neural field theories

Neural field models of firing rate activity have had a major impact in helping to develop an understanding of the dynamics seen in brain slice preparations. These models typically take the form of integro-differential equations. Their non-local nat... Read More about Waves, bumps, and patterns in neural field theories.

Clustering through post inhibitory rebound in synaptically coupled neurons
Journal Article
Chik, D. T. W., Coombes, S., & Wang, Z. D. Clustering through post inhibitory rebound in synaptically coupled neurons

Post inhibitory rebound is a nonlinear phenomenon present in a variety of nerve cells. Following a period of hyper-polarization this effect allows a neuron to fire a spike or packet of spikes before returning to rest. It is an important mechanism u...
