OxTalks will soon be transitioning to Oxford Events (full details are available on the Staff Gateway). A two-week publishing freeze is expected in early Hilary to allow all events to be migrated to the new platform. During this period, you will not be able to submit or edit events on OxTalks. The exact freeze dates will be confirmed as soon as possible.
If you have any questions, please contact halo@digital.ox.ac.uk
Recent advances in neuroanatomy and physiology make it possible to probe whole-brain mechanisms of cognition and behavior. However, as yet, few models in computational neuroscience have tackled the mechanisms underlying highly distributed neural activity during cognitive tasks. In this talk I will describe our anatomy-led approach to developing cortex-wide models of neural dynamics during cognitive tasks and our recent anatomical findings of gradients of neurotransmitter receptors in the cortex. I will highlight our investigations into how inputs from neuromodulatory systems may shift the cortical dynamical landscape, affecting cell-type specific interactions, and how this may confer flexibility on distributed cognitive functions such as conscious perception and working memory.
