On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
Modulating serotonergic signalling in the brain is the target of current first-line pharmacological approaches for the treatment of anxiety and depression. However, treatments such as SSRIs have considerable limitations, including a slow onset of their therapeutic effects and a lack of efficacy in treating some symptom clusters, in particular anhedonia and cognition. Emerging animal and human evidence suggests that specifically activating serotonin 4 receptors (5-HT4R) may be a promising target with the potential to provide more rapid, efficacious therapeutic effects. In preclinical models, 5-HT4R agonists rapidly reduce behavioural despair, anhedonia, and anxiety-like behaviour, and increase resilience to stress. Interest in this receptor has recently been stimulated by new evidence highlighting the key role that this receptor plays in human mood and cognition. In this seminar we will present human behavioural, neuroimaging and pharmacoepidemiological evidence, which has converged to demonstrate the considerable promise the 5-HT4R holds as a novel target for the treatment of depression, and in particular for treating the cognitive symptoms of the disorder which are not well addressed by conventional treatments.
