When someone asks, “Where is the mind located?” most people will automatically point to their heads. Why? Is it because we experience our thoughts in our heads? That seems the case most of the time, though when dreaming, one could argue that it gets a bit more ambiguous since we feel that we are “inside” our dreams. But for most of us, most of the time, “my head” is where “my mind” is located.

However, this may simply be because so many sense organs are located there: eyes, ears, nose, tongue. With so much information flowing into one part of the body, it might merely be habit that gives us the sense that the mind is in our head. (For example, you feel your ears sitting on either side of your face, but when a car backfires behind you, the sound can’t be felt entering the ear canal, being processed in the inner ear and then in the brain’s auditory center. Quite clearly the sound of the car comes from behind you. One could say, conversely, that hearing shoots out from the head into the world. This in fact was the view of some ancient cultures. We casually use this model for vision when we say that someone “shoots a glance” at someone else.)

Babies, we are told, have a much more diffuse experience of the senses, perhaps mixing them up in what are called synesthesias (e.g. experiencing sounds as colors or tastes as shapes, an experience reported from hallucinogenic drugs and in deep meditative states). Some researchers contend that babies have a poor sense of the boundary between themselves and the world. But infants turn into toddlers, and the separation between self and other starts to harden, as does the habitual experience that “my head is where I think.” Society and family reinforce this habit as the toddler grows up, and eventually the mind takes its seat in our heads, or so it seems.

This dovetails nicely with another cultural consensus that our minds are in our brains. Mind and brain have taken up residence together in a box called the skull. In this series of posts, however, we ask that you set aside your habits and assumptions to consider quite literally “thinking outside the box,” a process that goes on outside the skull but is still mental. Is the brain actually so closed up in its box that it makes sense to speak of it as though it were a machine for making mind, the way a laser printer makes documents? Is it possible that one could have a fully functioning and thinking brain sitting in a pan on a lab bench as in some 1950’s science fiction movie? (Successful head transplants have been performed in laboratory animals, but since there is no technique for reattaching the spinal cord, the animal was left a quadriplegic. Such procedures are controversial, for obvious ethical and humane reasons.) We should be open to asking some culturally radical questions, including the most radical of all: Is a brain even necessary for “thinking”? There are different ways to explore these issues.

First, let’s consider whether only human brains create minds. Few people who have pets or live on farms or go camping would say that the animals they encounter don’t have minds. (This view accords with abundant evidence that the genes, receptors, and neurotransmitters involved in human brain function are present in animals.) Again, if we are asked, “Where is your cat’s mind?” we’d point at its head (unlike an ancient Egyptian, Greek or Roman, who would point to the heart, as he would for himself). Saying that different kinds of animal brains create minds is not so troublesome. We aren’t able to describe what those minds are like (some may lack anything like human self-awareness), but we shouldn’t have a problem conceiving that these creatures at least have one.

Evolutionarily, nervous systems are not always central. Some creatures, like jellyfish, have neuronal nets distributed throughout the body. While humans do possess a central nervous system, we also have other, more distributed nervous systems as well. We have a peripheral nervous system, which includes nerves that gather information for the brain (e.g. the nerves in our sense organs) and nerves that send signals from the brain (e.g. telling our muscles what to do).

After it was observed that the gastrointestinal tract could function quite well when severed from the peripheral nervous system, it was concluded that this constitutes a weblike enteric nervous system.

What makes this a separate nervous system is that there are specialized ganglion cells that are located between muscle layers in the intestinal wall which act like a local brain. If one severs any nerves which contact them (from the brain, by way of the peripheral nervous system), these ganglion cells continue to instruct the intestine to move and absorb and secrete, working quite well and quite autonomously as a self-contained functional unit.
It turns out that the intestinal tract only takes advice from the rest of the body. It harbors its own reactions. When bad news gives you a sinking feeling in the pit of your stomach, you are experiencing an emotion as surely as you experience it in your head. In fact, your gut reaction precedes the thought, “Oh no!” Did the enteric nervous system create such a sensation on its own? That’s unclear, but it’s tempting to think so. Certainly many people trust their gut reactions over the confused and compromised responses that the brain is often saddled with when over-thinking sets in.

The muscles of your face are directly linked to your brain. While we assume that the brain is telling the mouth and lips to smile when we’re feeling happy, the reverse is also true. Seeing a smile on someone else’s face can make you happy, and children are taught to smile as a way to break out of a sad mood. Whether this works or not varies from person to person, but it could be argued that the face is controlling the brain in those instances.

Findings about brain-like processes outside the skull have become common. The conduction system of the heart, which organizes your heartbeat, can be thought of as the heart’s brain in the same way the ganglion cells in the gut are the brain of the intestines. The independence of the conduction system is shown when a transplanted heart keeps beating even though the nerves that connected it to the donor’s central and peripheral nervous systems have been severed. The interaction between the heart’s independent processing and the brain’s is complex and not fully understood. Still more mysterious are the bacteria that outnumber the body’s cells by ten to one, living mostly inside the digestive tract but also in the brain and other organs. We think of these as invaders, but over eons bacteria have been incorporated into vast stretches along the double helix of human DNA. The implications for what we call “being human” are enormous and largely uncharted.

We think we’ve established that cultural assumptions about mind and brain are full of gaps. The location of mind is in doubt, and any attempt to isolate it physically in the skull run into valid objections. In the next post we’ll pursue more of the fascinating possibilities that arise when thinking literally gets out of the box.

It caused a stir when Sam Harris, in a new book titled Waking Up, changed his message from militant atheism to peaceful Buddhism. A positive message is better than a negative one, and since Buddhism is often labeled as “a religion without God,” Harris's move isn't as radical as it looks at first
