My point was it is impossible to separate the two in practice. Enhanced sensory input will affect cognition and enhanced cognition will affect sensory inputs. Depending on the kind of sensory enhancement it might lead to impaired cognition but I'm using the colloquial sense of enhancement to mean "making better". You can certainly "enhance" a signal with noise and make it worse.
