Neuroessentialism is the belief that you , your mind, your identity, are essentially just your brain. It gets touted as an example of how science has triumphed, once again, over superstitions of the past - your soul hasn't died , it was just an illusion! Created by the brain. With memory, sensation, speech, and just about every other human attribute found to be located in one gyrus or another, it seems like there isn't anything left that could be outside of the brain. Francis Crick referred to this as the “astonishing hypothesis[1],” and while Stephen Pinker pointed out that for most neuroscientists this idea hardly warranted much astonishment[2], what might be more astonishing is how quickly the idea is bleeding out of the laboratory into popular media.  The basic philosophical foundations of this notion have been around for a long time (as mentioned on the [highly entertaining] podcast “ very bad wizards, ” we've known for a long time that when you remove the head, the mi...

Imagine you find that a beloved uncle has received a terrible injury that leaves him paralyzed, but still totally aware of his environment - a condition known as locked in syndrome . Now imagine that a doctor comes to you with a miracle cure: a new experimental treatment will repair your uncle's damaged brainstem allowing him to regain control of his body. The catch, however, is that this procedure is extremely painful. It actually seems like it might be the most painful experience possible: fMRI scans reveal that all the brain regions that are active during extreme pain are activated during this (imaginary) procedure. And it lasts for hours. However, your uncle won't complain about the procedure because 1) he's paralyzed and thus can't voice his suffering, and 2) the experience of this miracle treatment will mercifully be forgotten once the procedure is over, so your uncle won't raise any complaint afterwards. While many of us would probably sign off on the procedu...

50,000 cultured brain cells sit in a petri dish. Through a combination of electronic sensors, software engineering and robotic sculpture , the physiology of the cells interacts with the psychology of some patrons of an art gallery [1]. From this transaction, judgments arise - the audience might report feelings of being watched, of play, or simply of remotely observing an oblivious 'seizure machine.' One particular type of audience member, the Animal Ethicist, might even wonder if we should be worried that the culture of brain cells (as a former animal) might be in pain. Brain cells, electrodes, and tiny Peter Singer (image from here ).  While in most cases it is fairly straightforward to determine that a human is in pain, when one starts to asks if non-humans (or even humans with severe communication problems, such as locked-in patients) are in pain, it is common to turn to neuroscience for help. The idea is that while mental states (such as pain and suffering) can only b...
