Did You Know You Have a Second Brain?

Our guts operate on a quite separate nervous system. Learning more will help control gastrointestinal diseases

Our huge gastrointestinal tracts operate their own nervous system, using neurons that follow different principles from those of brain neurons, according to recent findings: Our approximately seven-meter long gastrointestinal (GI) tract has its own functionally distinct neurons. Since this enteric nervous system (ENS) operates autonomously, it is sometimes referred to as the “second” or “abdominal” brain. While the ENS controls muscle movement (peristalsis) in the gut and its fluid balance and blood flow, it also communicates with the immune system and microbiome. Karolinska Institutet, “New fundamental knowledge of the ‘abdominal brain’” at Medical Xpress (December 7, 2020) Paper. (subscription required) The Karolinska researchers made progress in studying the little-understood second brain by mapping the neuron types in the digestive systems…

Study: The Expression of Human Emotions Is Universal

Most representations in visual arts depend on the universality of human emotion

Most of us wouldn’t be surprised to learn that the expression of human emotions is universal. But today there is a study for everything and 16 “universal human emotional expressions” have been identified: Whether at a birthday party in Brazil, a funeral in Kenya or protests in Hong Kong, humans all use variations of the same facial expressions in similar social contexts, such as smiles, frowns, grimaces and scowls, a new study from the University of California, Berkeley, shows… Researchers at UC Berkeley and Google used machine-learning technology known as a “deep neural network” to analyze facial expressions in some 6 million video clips uploaded to YouTube from people in 144 countries spanning North, Central and South America, Africa, Europe,…

Can We Teach a Computer to Feel Things? A Dialogue…

Okay, There’s the computer’s side… and then there’s the dog’s side. Listen to both

The dialogue got started because of a gifted computer nerd, Rosalind Picard, also a playwright (pictured), who decided to become an evangelical Christian in midlife (approx 2019). As she tells it, “a flat, black-and-white existence suddenly turned full-color and three-dimensional.” The director of MIT’s Media Lab, she had also written a book in 2000 called Affective Computing which seems to suggest that one could somehow give emotions to machines. I asked Eric Holloway to help me figure that one out: O’Leary: Emotions are based on actual well-being or suffering. How can something that is not alive have actual emotions? Don’t think of people here!; think of dogs. Dogs have emotions. When my computer is giving trouble, I certainly hope it’s…

Multiverse Physicist Max Tegmark Seeks AI That Checks News Bias

Naive people who truthfully claim to be acting only “for good” in trying to address bias in the news via AI are kidding themselves

Max Tegmark (right) is probably better known as a multiverse cosmologist than as an AI specialist. The MIT physics professor told New Scientist in 1998 that “All possible universes exist, even triangular ones.” He also informed Scientific American in 2003 that “Not just a staple of science fiction, other universes are a direct implication of cosmological observations”: Is there a copy of you reading this article? A person who is not you but who lives on a planet called Earth, with misty mountains, fertile fields and sprawling cities, in a solar system with eight other planets? The life of this person has been identical to yours in every respect. But perhaps he or she now decides to put down this…

At least it would be easier for the machines if we did
Efforts to enable machines to read our emotions are hitting a roadblock and, oddly enough, Charles Darwin, founder of popular evolution theory, plays a role in getting it wrong. Read More ›
