Why should the neural activity be statistical?

Even for the same event 1, the neural activity is variable, implying the ambiguity in the representation of the world events. To put in other words, same events can cause multiple observations in the brain. For the brain, an observation can be caused by many events. The lack of one-to-one mapping from the event space to neuronal space should then have a translation. For this translation, the neuronal activity should have a pattern, thence making it inherently statistical.

  1. It is tricky to use the term ‘same event’. The brain machinery has limited resource capacity and hence can only represent limited information. So the observed event can only have a limited representation. Further, even if we had an exact reproduction of an event, an exact reproduction of the observed event would mean that the machinery forgets completely about that previous production of that event.
