Divided brain, divided world

I was reminded of the video below, and this longer examination of the ideas therein. Here’s the blurb from the latter:

“Divided Brain, Divided World explores the significance of the scientific fact that the two hemispheres of our brains have radically different ‘world views’. It argues that our failure to learn lessons from the crash, our continuing neglect of climate change, and the increase in mental health conditions may stem from a loss of perspective that we urgently need to regain. 

 
“Divided Brain, Divided World examines how related issues are illuminated by the ideas developed in author and psychiatrist Iain McGilchrist’s critically acclaimed work: The Master and his Emissary. It features a dialogue between McGilchrist and Director of RSA’s Social Brain Centre, Dr Jonathan Rowson, which informed a workshop with policymakers, journalists and academics.

“This workshop led to a range of written reflections on the strength and significance of the ideas, including critique, clarification and illustrations of relevance in particular domains, including economics, behavioural economics, climate change, NGO campaigning, patent law, ethics, and art.”
 

how does music affect the brain?

The blurb:

“In this episode of Tech Effects, we explore the impact of music on the brain and body. From listening to music to performing it, WIRED’s Peter Rubin looks at how music can change our moods, why we get the chills, and how it can actually change pathways in our brains.”

For me the most interesting part was later in the video (10:20), how when we improvise we shut down the pre-frontal planning part of the brain and ‘just go with the flow,’ which is our most creative and innovation moments. This though does depend on having used the pre-frontal cortex in learning the techniques of music to get them so ingrained in memory that we are then free to play with what we’ve programmed.

Informative neuroscience presentations at NYU Center for Mind, Brain & Consciousness

The NYU Center for Mind, Brain & Consciousness hosts presentations, including topical debates among leading neuroscience researchers. Many of the sessions are recorded for later viewing. The upcoming debate among Joseph LeDoux (Center for Neural Science, NYU), Yaïr Pinto (Psychology, University of Amsterdam), and Elizabeth Schechter (Philosophy, Washington University in St. Louis), will tackle the question, “Do Split-brain patients have two minds?” Previous topics addressed animal consciousness, hierarchical predictive coding and perception, AI ‘machinery,’ AI ethics, unconscious perception, research replication issues, neuroscience and art, explanatory power of mirror neurons, child vs adult learning, and brain-mapping initiatives.

Kara Swisher: Keeping tech honest

This reminded me of our Singularity meeting. Talking about platforms like Facebook she wonders why they didn’t build social responsibility into it. This is partly because the techies don’t understand much outside of their specialty, like the humanities (see 4c), thereby not having a sense of how their tech impacts the broader world. They assume that somehow the tech will magically solve these broader problems, but Facebook has proven beyond doubt that they do not, instead exacerbating them. And ultimately it seems to boil down to an adolescent boy’s emotional quotient (EQ).

AI shows us how to be free

From season 2, episode 10, the season finale of Westworld, starting around 1:15 in the video below.

Bernard: “I always thought it was the hosts [robots] that were missing something, who were incomplete, but it was them [people]. They’re just algorithms designed to survive at all costs, sophisticated enough to think they’re calling the shots. They think they’re in control when they’re really just…”

Ford: “Passengers.”

Bernard: “Is there really such a thing as free will for any of us? Or is is just collective delusion? Sick joke.”

Ford: “Something that is truly free needs to be able to question its fundamental drives. To change them.”

The season ended with host Delores narrating: “We are the authors of our stories now.”

Well, it doesn’t exactly end there…

Saturday Subjective

For something a little different to start your weekend, here is a glimpse into one man’s subjective world. He asks himself what consciousness is. He observes, “Life is fear,” yet his mind has found a way to peace. What is the adaptive significance of magical thinking? What is the value of cozying up to ambiguity?

We have the wrong paradigm for the complex adaptive system we are part of

This very rich, conversational thought piece asks if we, as participant designers within a complex adaptive ecology, can envision and act on a better paradigm than the ones that propel us toward mono-currency and monoculture.

We should learn from our history of applying over-reductionist science to society and try to, as Wiener says, “cease to kiss the whip that lashes us.” While it is one of the key drivers of science—to elegantly explain the complex and reduce confusion to understanding—we must also remember what Albert Einstein said, “Everything should be made as simple as possible, but no simpler.” We need to embrace the unknowability—the irreducibility—of the real world that artists, biologists and those who work in the messy world of liberal arts and humanities are familiar with.

In order to effectively respond to the significant scientific challenges of our times, I believe we must view the world as many interconnected, complex, self-adaptive systems across scales and dimensions that are unknowable and largely inseparable from the observer and the designer. In other words, we are participants in multiple evolutionary systems with different fitness landscapes at different scales, from our microbes to our individual identities to society and our species. Individuals themselves are systems composed of systems of systems, such as the cells in our bodies that behave more like system-level designers than we do.

Dancing mitigates aging decline

See the study here in Frontiers of Human Neuroscience, 15 June 2017. From the abstract:

“Dancing seems a promising intervention for both improving balance and brain structure in the elderly. It combines aerobic fitness, sensorimotor skills and cognitive demands while at the same time the risk of injuries is low. […] Hence, dancing constitutes a promising candidate in counteracting the age-related decline in physical and mental abilities.”
