Brain is a group of neurons connected by synapses.
Collective mind = we are
We are group of neurons. We just have another connections: we are using words, music, art, vision , phone, internet etc..
There is a new step of society evolution. In future communications will be easier.
Have you ever thought about it?
How can you see future of collective mind?
Yes, I have thought about it. It's on another thread somewhere.
A neuron doesn't think by itself, but a group of neurons (like a brain) thinks. The interaction beteween the neurons is the thought.
And on a higher level, the interactions between brains (people) is another thought like a collective mind.
Sure.
