OxTalks is Changing
Oxford Events, the new replacement for OxTalks, will launch on 16th March. From now until the launch of Oxford Events, new events cannot be published or edited on OxTalks while all existing records are migrated to the new platform. The existing OxTalks site will remain available to view during this period.
From 16th, Oxford Events will launch on a new website: events.ox.ac.uk, and event submissions will resume. You will need a Halo login to submit events. Full details are available on the Staff Gateway.
Neurotransmitter receptor gradients: gateways for neuromodulation of cortex-wide dynamics during cognition
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.
