Dear Users
Today (4.30-5.30 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. The talk will
illustrate one way of making statistical comparisons across experimental
conditions in MEG.
Everyone is welcome to attend.
Best wishes
Rebecca
