Attentional Gain Modulation as a Basis for Translation Invariance
Inferotemporal (IT) neurons in monkeys can respond to visual stimuli in a translation- and scale-invariant manner. In a neural circuit model based on a recently reported form of gain modulation by attention in area V4, the modulated visual responses of model V4 neurons produce object-centered receptive fields further down the visual processing stream, accounting for invariances exhibited by IT neurons.
