Actually the opposite. The story of a single neuron on/off state for everything we experience is just that, a story. If you tried to build a skull large enough to hold all that, it would burst. The reality is that paradigm of hardwired neurons works well for the initial layers of processing (Eg recognizing lines and circles in visual stimuli), but that same model can't be repeated all the way up to the point of having a "grandmother neuron" for recognizing Grandmas face. There's just too many possible states of grandmas. There has been some evidence (like this study) that maybe sometimes there are "sparsely coding neurons" (Eg, some monkeys apparently have a brain cell that reliably responds to seeing Jenifer Aniston and nothing else). But such sparse coding (if it exists) is the exception not the rule. https://www.youtube.com/watch?v=_njf8jwEGRo https://www.youtube.com/watch?v=_njf8jwEGRo
