In Pursuit of a Mind Map, Slice by Slice

Mapping the brain at the connectome level seems daunting, but it’s an exciting step in understanding how our brains work. As noted in the article, the connectome is a series of static images, so it would seem that the next stage, perhaps massively more complicated, would be studying the connectome’s action in time. – Ilene

In Pursuit of a Mind Map, Slice by Slice

By ASHLEE VANCENY Times

Excerpts:

Dr. Lichtman and his team of researchers at Harvard have built some unusual contraptions that carve off slivers of mouse brains as part of a quest to understand how the mind works. Their goal is to run slice after minuscule slice under a powerful electron microscope, develop detailed pictures of the brain’s complex wiring and then stitch the images back together. In short, they want to build a full map of the mind.

The field, at a very nascent stage, is called connectomics, and the neuroscientists pursuing it compare their work to early efforts in genetics. What they are doing, these scientists say, is akin to trying to crack the human genome — only this time around, they want to find how memories, personality traits and skills are stored.

[...]

Dr. Lichtman estimates it will be several years before they can contemplate a connectome of a mouse brain, but there are some technological advances on the horizon that could cut that time significantly. Needless to say, a human brain would be far more complex and time-consuming.

“Hopefully, we are returning with a burst of new energy to the question of how the brain is wired up,” said Gary S. Lynch, a well-known brain researcher at the University of California, Irvine. “Lacking a blueprint, we’re never going to get anywhere on the most profound and fun questions that drew everyone to neuroscience in the first place: what is thought, consciousness?”

How your brain remembers the future

Déjà vu, all over again.

How your brain remembers the future

Image Of Thinking Man's Brain Through Bowler Hat

By NewScientist

IT’S like remembering the future. Our brain generates predictions of likely visual inputs so it can focus on dealing with the unexpected.

Predictable sights trigger less brain activity than unfamiliar stimuli, bolstering the view that the brain is not merely reactive, but generates predictions based on the recent past. "The brain expects to see things and really just wants to confirm it now and again," says Lars Muckli at the University of Glasgow, UK.

[...]

The finding supports the "Bayesian brain" theory, which sees the brain as making predictions about the world which it updates when new information comes in.

Disorderly genius: How chaos drives the brain

Here’s a fascinating New Scientist article on how your brain works, swinging back and forth between order and chaos, neurons firing away in a blizzard of random activity. – Ilene

Disorderly genius: How chaos drives the brain 

chaotic brain, geniusBy David Robson

HAVE you ever experienced that eerie feeling of a thought popping into your head as if from nowhere, with no clue as to why you had that particular idea at that particular time? You may think that such fleeting thoughts, however random they seem, must be the product of predictable and rational processes. After all, the brain cannot be random, can it? Surely it processes information using ordered, logical operations, like a powerful computer?

Actually, no. In reality, your brain operates on the edge of chaos. Though much of the time it runs in an orderly and stable way, every now and again it suddenly and unpredictably lurches into a blizzard of noise.

Neuroscientists have long suspected as much. Only recently, however, have they come up with proof that brains work this way. Now they are trying to work out why. Some believe that near-chaotic states may be crucial to memory, and could explain why some people are smarter than others.

In technical terms, systems on the edge of chaos are said to be in a state of "self-organised criticality". These systems are right on the boundary between stable, orderly behaviour – such as a swinging pendulum – and the unpredictable world of chaos, as exemplified by turbulence…

Any firm that approaches $1T in value has tapped into a basic human instinct. Consuming, signalling, loving, and praying have been the fuel of Amazon, Apple, Facebook, and Google’s ascents, respectively. That the crypto asset class universe has reached $2T reveals, I believe, that it taps into two attributes we instinctively pursue: trust and scarcity.

Canada's Green Shift Could Displace Three-Quarters Of Oil Workers

Courtesy of Charles Kennedy, OilPrice.com

Canada’s climate strategy to significantly cut emissions and become a net-zero emissions economy by 2050 will create a seismic shift in the large oil and gas sector, where up to three-quarters of the workers, or up to 450,000 people, are at risk of displacement, TD Bank said in a new report on Tuesday.

Canada aims to become a net-zero emissions economy within three decades, and to cut emissions by between 32 percent and 40 percent by 2030.

While those commitments could be critical to staving off the worst effects of gl...

Janet Yellen speech named "International Priorities — Remarks to The Chicago Council on Global Affairs" (here) can be summed to (via Luke Gromen) :


The US is accelerating a move away from "subjugating the US middle and working class to support the USD", to "subjugating the USD to support the US middle and working classes".

Gold; Load Up The Truck Upon Hitting This Level

Gold has created lower highs since peaking last summer. Is Gold near a low? Where would a nice entry point come into play?

This chart looks at Gold ETF (GLD) on a weekly basis over the past few years. GLD hit the top of this rising channel at (1) last summer, as it was above moving averages and relative strength was hitting lofty levels.

The decline over the past 7-months has GLD creating a death cross. Warren Buffett sold his Gold holding before this death cross took place!

Where would one want to pick up some GLD at a nice risk/reward price point?

If GLD reaches rising channel support at (2), w...

Adaptive Fibonacci Price Modeling System Suggests Market Peak May Be Near

Courtesy of Technical Traders

Our Adaptive Fibonacci Price Modeling system is suggesting a moderate price peak may be already setting up in the NASDAQ while the Dow Jones, S&P500, and Transportation Index continue to rally beyond the projected Fibonacci Price Expansion Levels.  This indicates that capital may be shifting away from the already lofty Technology sector and into Basic Materials, Financials, Energy, Consumer Staples, Utilities, as well as other sectors.

This type of a structural market shift indicates a move away from speculation and towards Blue Chip returns. It suggests traders and investors are expecting the US consumer to come back strong (or at least hold up the market at...

The numbers of new cases in some of the hardest hit COVID19 states have started to plateau, or even decline, over the past few days. A few pundits have noted it and concluded that it was a hopeful sign. 

Is it real or is something else going on? Like a restriction in the numbers of tests, or simply the inability to test enough, or are some people simply giving up on getting tested? Because as we all know from our dear leader, the less testing, the less...
