Question

How can neurons generate consciousness?

Answer 1

Consciousness is the result of the cooperation of a multitude of neurons in Neural Networks.

Explanation:

A single neuron can't create consciousness. Consciousness is the result of a myriad of neurons working together in Neural Networks: the concepts, structures and identities of which are not fully understood.
The exact process is still largely unclear, though in recent times some progress have been made.
