No, it can't be done for a lot of reasons. Here are just a few. 1) Memories are stored in electrical pathways, not the the cells themselves. You don't have 1000 memories in a chunk of brain that contains 1000 neurons. If you don't get the entire pathway, you won't get the memory. 2) Once a nerve is cut, it won't fuse with another cut nerve. All you'll have ...

The answer to this question is complicated, but assume it's not for the moment. The easy answer is that our eyes can detect patterns we're familiar with and "produce" an answer in the form of a number. Unfamiliar patterns do not produce this 'number'. Take a die. We are immediately aware of the number of dots in the typical arrangement of one to six. We ...

I think this website provides a pretty surprisingly thorough breakdown of avian brain anatomy, including historical contexts and debate around what exactly is homologous and what is not, and whether 'homologous' is a useful bit of information. In short: It was thought until recently that the bird brain was just the core of the mammal brain with some layers ...

Reverse signals (dendrite -> axon) do occur in neurons, and are called back propagating action potentials (bAPs). However, whatever role bAPs play in the nervous system at large is subtle/small enough that we don't really understand them at all. In any case, as @luigi points out, pinched nerves don't have anything to do with bAPs. The reason why a pinch in ...

This isn't a ridiculous idea; Transcranial Magnetic Stimulation is used in research and even has some use as treatment for depression (http://www.mayoclinic.org/tests-procedures/transcranial-magnetic-stimulation/basics/definition/prc-20020555) In TMS a strong, localized magnetic field can disrupt normal functioning of regions of the brain. For instance it ...
