What Can You Do Without a Brain?

Well, what can you do?

This is one of the many questions that draws me to the field of biology… More specifically, neuroscience.

Other creatures on Earth are known to survive without a brain, like cockroaches, but can humans?

Unfortunately, the answer is no. We pretty much need our brain for everything. The reason cockroaches can survive without a head is because they have little bundles of nervous tissue throughout their bodies, which are responsible for basic nervous functions, like reflexes.


But there comes a point when people wonder if our involuntary responses and actions really need our brain to function. If we aren’t consciously thinking about it, does it mean our brains aren’t involved?

I don’t think so… I think having a brain is a very necessary thing for us humans – don’t you?
