Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: In order to form stable perceptual representations, populations of sensory neurons must pool their output to overcome physiological noise; selective attention is then required to ensure that behaviorally relevant stimuli dominate these ‘population codes’ to gain access to awareness. Hover, the role that attention plays in shaping population response pro" les has received little direct investigation, in part because most traditional neurophysiological methods cannot simultaneously assess changes in activity across large populations of sensory neurons. Based on single-unit recording studies, current theories hold that attending to a relevant feature sharpens the population response pro" le and improves the signal-to-noise ratio of the resulting perceptual representation. Here,  test this hypothesis using fMRI and an analysis approach that is able to estimate the in! uence of feature-based attentional modulations on population response pro" les.  " rst derive orientation tuning functions for single voxels in human primary visual cortex, and then use these tuning functions to sort voxels according to their orientation preference.  then show that selective attention systematically biases population response pro" les so that behaviorally relevant stimuli are represented in the visual system at the expense of behaviorally irrelevant stimuli. Collectively, the present results (1) provide a new approach for precisely characterizing feature-selective responses in human sensory cortices and (2) reveal how behavioral goals can shape population response pro" les to support the formation of coherent perceptual representations.
