revised Why does squinting allow you to see objects more clearly?
English of title; not clear(er) objects, but "more clearly see"...

comment How does the brain know where a signal came from? What is the addressing system
Is it precisely 1-to-1? The number of somatosensory neurons < axons in spinal cord to brain? I don't think this is absolutely true, but not sure. For example on your back, you have a very coarse sensation, but there's no missing area of sensation. To save bandwidth, it is plausible that there were some converging signals in the spinal cord level.

comment Will we ever be able to read the thoughts from brain activity?
@Manu So primarily brain-machine interfaces? I think you can rephrase your question to a more scientific one, if only you can define "thoughts". With current technology, we can read out many things pretty well, and it's only gonna get better.

comment What is the current consensus, if any, about why long term potentiation is not clearly correlated with learning?
@Joebevo learning may require strengthening, weakening, or both of synapses. It will depend on many things including the learning task, context, which synapses, and so on.

Can you clarify what you mean by "LTP is correlated with learning"? Learning is a complex process and synaptic plasticity is certainly a necessary biological process.
