The Relationship of Visual Perception and Perceptual Binding to Single Cell Activity. (360G-Wellcome-064486_Z_01_A)

£15,547

The research project will be to record from the pulvinar nucleus of the thalamus in alert animal models trained to perform a classical conjunction search' task, where the target item is a unique combination of two features (e.g. blue & tilted amidst a display of orange tilted and blue vertical bars, say). Correct performance of the task demonstrates that the target features blue' and tilted' have been correctly bound to each other (and/or to the corresponding object location in space). Individual pulvinar neurons are notexpected to demonstrate pronounced selectivity for either colour, or orientation (although, if they do, the course of the experiment and its validity are not affected). The single unit response, local field potential (LFP - recorded from the same electrode) and the spike-LFP coherence will be monitored while either a target or nontarget is present within the receptive field. The task difficulty will be varied while recording at the same site, inorder to obtain a measure of the neural-behavioural correlate in terms of % correct performance.
