I'm interested in reading on the influence of exogenous attention on cortical representations in early visual areas, but so far my google-fu seems to be failing me.
There seems to be some literature involving endogenous attention (Kamitani & Tong 2006, for instance), but nothing involving cueing, for instance.
Does anybody know of any papers demonstrating either of the following?
- fMRI decoding of the effects of attentional cueing on V1?
- fMRI decoding of (cued) attentional effects on V1 activity using at-threshold stimuli?
Thanks very much in advance!
Edit: Okay, so I found two that hit the topic center-mass:
- Kok et al., 2011 Less Is More: Expectation Sharpens Representations in the Primary Visual Cortex
- Kok et al., 2012 Attention Reverses the Effect of Prediction in Silencing Sensory Signals
