How the body and mind talk to one another to understand the world

By Sarah Garfinkel – When considering the senses, we tend to think of sight and sound, taste, touch and smell. However, these are classified as exteroceptive senses, that is, they tell us something about the outside world. In contrast, interoception is a sense that informs us about our internal bodily sensations, such as the pounding of our heart, the flutter of butterflies in our stomach or feelings of hunger.

The brain represents, integrates and prioritizes interoceptive information from the internal body. These are communicated through a set of distinct neural and humeral (ie, blood-borne) pathways. This sensing of internal states of the body is part of the interplay between body and brain: it maintains homeostasis, the physiological stability necessary for survival; it provides key motivational drivers such as hunger and thirst; it explicitly represents bodily sensations, such as bladder distension.

But that is not all, and herein lies the beauty of interoception, as our feelings, thoughts and perceptions are also influenced by the dynamic interaction between body and brain.

The shaping of emotional experience through the body’s internal physiology has long been recognized. The American philosopher William James argued in 1892 that the mental aspects of emotion, the ‘feeling states’, are a product of physiology. He reversed our intuitive causality, arguing that the physiological changes themselves give rise to the emotional state: our heart does not pound because we are afraid; fear arises from our pounding heart. more>

The Boundary Between Our Bodies and Our Tech

By Kevin Lincoln – Many of the boundary lines in our lives are highly literal, and, for the most part, this is how we’ve been trained to think of boundaries: as demarcations shored up by laws, physical, legal, or otherwise, that indicate exactly where one thing ends and another begins. Here is the border of your property; here is the border of your body; here is the border of a city, a state, a nation—and to cross any of these boundaries without permission is to transgress.

But one of the most significant boundary lines in our lives is not this way, and one piece of ubiquitous technology is making this line increasingly permeable and uncertain, at a cost that we may only be starting to comprehend.

The debate over what it means for us to be so connected all the time is still in its infancy, and there are wildly differing perspectives on what it could mean for us as a species. One result of these collapsing borders, however, is less ambiguous, and it’s becoming a common subject of activism and advocacy among the technologically minded. While many of us think of the smartphone as a portal for accessing the outside world, the reciprocity of the device, as well as the larger pattern of our behavior online, means the portal goes the other way as well: It’s a means for others to access us. more>
