The electronic devices communicate directly with sensory areas of the brain, bypassing damaged or destroyed eyes and limbs.

I assert that intellectual seizures do not exist. Dr. Ali asserts that they do exist and that they do not. The difference between their existence and their non-existence seems to be Dr. Ali’s rhetorical needs of the moment.

Is there evidence that human minds function like computers and can soon be reproduced in software, as Hofstadter believed?

I know of no report in medical history of an abstract thought evoked by a seizure or by brain stimulation. Which is odd, if the brain causes abstract thought.

Neurobabble is a full-employment campaign for neuroscientists. Recast obvious social or psychological facts as brain events and you’ll never be out of work.

The study found that our dislike of almost-human bots is a “hardwired” natural reaction to something that doesn’t seem quite right.

Yale University neurologist Steven Novella posted recently on the science of growing brain tissue in the lab. It’s interesting stuff, but then we come to the jumbled metaphysical musings that conclude his post: There is a layer of weirdness to the very idea of brain tissue in a vat, because I think we are naturally uncomfortable with the very notion that our consciousness is the result of a clump of tissue shuttling ions around. It breaks the illusion that our brains evolved to have, a very compelling and persistent illusion – namely that the reality we perceive is real, rather than a constructed representation. That internal representation has a strong relationship to physical reality, but the two are not the Read More ›
Neurosurgeon Michael Egnor was featured in a short film as a supplement to the Science Uprising series. There, he mentions four researchers who have shed light on the non-material mind nature of our minds: Wilder Penfield (1891–1976): Some of the earliest evidence came from neurosurgeon Wilder Penfield, who was the pioneer in epilepsy surgery in the mid 20th century. Penfield operated on over a thousand epilepsy patients while they were awake (under local anesthesia), and he stimulated their brains with electrodes in order to identify epileptic regions for surgical resection. He carefully recorded their responses to stimulation. In his book Mystery of the Mind, (1975) Penfield noted: “When I have caused a conscious patient to move his hand by applying Read More ›
Seizures never evoke abstract thought. That is, if a seizure causes you to think about a triangle, it always causes you to imagine a particular triangle, not to define triangles abstractly.

Here is one way of seeing it: If someone took a sledgehammer to your computer and pulverized it, yet it still worked fairly well, you would conclude that there was something rather strange about the computer that you had not previously considered.

There is growing evidence that many comatose patients are quite aware of what is going on around them. For example, nurses are often very careful not to say upsetting things that the patient can hear because blood pressure often rises dramatically, even in deeply “unaware” comatose patients.

The attribution of abstract thought to the material brain is philosophical and logical nonsense and has been repeatedly discredited by the best neuroscience over the past century.

There may indeed be material explanations (at least from the perspective of neuroscience) but the simplest and most convincing explanation for the results of many experiments is that abstract thought is an immaterial power, not a material power, of the mind.

Beyond that, such research raises a philosophical question: If the mind is an illusion, how can it act directly on external things, by the force of decision-making alone?

Jonathan Sackier emphasizes that, when dealing with sufferers from severe or chronic brain injury, medicine must not raise false hopes: “So we have a profound obligation to be honest, open, transparent, and to do darn good science!” But he is optimistic.

The media’s monolithic obsession with denying human uniqueness comes at a cost. The remarkable fact that two life forms have the same number of neurons but one displays significantly more complex behavior than the other is drowned out by the volume of misrepresentation.

People who have come back from catastrophic injuries like Bill Zoller's intrigue neuroscientists because they offer a glimpse into the neuroplasticity that enables the brain to restore lost functions, which we can learn to augment.
