According to psychology research on human perception there is indeed something that you could call buffered IO in the human brain.
It's used in theories to explain why you can hear your name in a short sentence in a crowded room and then know what the sentence is. Including one or two words before your name. While if your name wasn't said, no attention is diverted to that sound and the "buffer" contents get dropped without retrieving the information.
Yes, and there's different buffers with different capacity for different types of perception according to these theories. Look up Baddeley & Hitch for details. I would guess there are similar buffers for other senses that didn't make it in the lectures in college.
