Neural mechanisms of selective attention

We study the relationship between selective attention, gamma rhythm and a neural mechanism called normalization, which has been recently associated with attention. For example, we found that the effect of normalization and attention are highly correlated across neurons in MT (Ni, Ray and Maunsell, 2012, Neuron), and gamma power was correlated with the strength of normalization, independent of attentional load (Ray, Ni and Maunsell, 2013, PLoS Biology).
