Dear Users This week (4-5 pm YNiC open plan) Andy Ellis will give a talk on "Semantically-driven re-activation of visual cortex in object recognition?". Summary: Magnetoencephalography was used to probe the nature and time course of responses to early and late acquired objects in a covert naming task. Analysis focused on regions in left occipital and anterior temporal cortex that have been reported to show stronger responses to early than late acquired objects in fMRI. An evoked response in visual cortex around 170 ms was followed by an evoked response in anterior temporal cortex (150-250 ms) that was stronger to early than late acquired objects. This was followed by an induced re-activation of visual cortex from 250 ms onwards that was also modulated by age of acquisition. Everyone is welcome to attend.
