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…

Is The Drone Strike a Black Swan?

Courtesy of Lee Adler

Pundits are calling yesterday’s drone strke a “black swan.” Can a drone strike on a Saudi oil facility, be a “black swan.”

According to Investopedia:

A black swan is an unpredictable event that is beyond what is normally expected of a situation and has potentially severe consequences. Black swan events are characterized by their extreme rarity, their severe impact, and the practice of explaining widespread failure to predict them as simple folly in hindsight.

I seriously doubt that no one expected or could have predicted a drone strike on a Saudi oil facility.

Crude Oil Cycle Bottom aligns with Saudi Oil Attack

Courtesy of Read the Ticker

Do the cycles know? Funny how cycle lows attract the need for higher prices, no matter what the news is!

These are the questions before markets on on Monday 16th Aug 2019:

1) A much higher oil price in quick time can not be tolerated by the consumer, as it gives birth to much higher inflation and a tax on the average Joe disposable income. This is recessionary pressure.

2) With (1) above the real issue will be the higher interest rate and US dollar effect on the SP500 near all time highs.

3) A moderately higher oil price is likely to be absorbed and be bullish as it creates income for struggling energy companies and the inflation shock may be muted. 

We shall see.

Despacito - How to Make Money the Old-Fashioned Way - SLOWLY!

Are you ready to retire?  

For most people, the purpose of investing is to build up enough wealth to allow you to retire.  In general, that's usually enough money to reliably generate a year's worth of your average income, each year into your retirement so that that, plus you Social Security, should be enough to pay your bills without having to draw down on your principle.

Unfortunately, as the last decade has shown us, we can't count on bonds to pay us more than 3% and the average return from the stock market over the past 20 years has been erratic - to say the least - with 4 negative years (2000, 2001, 2002 and 2008) and 14 positives, though mostly in the 10% range on the positives.  A string of losses like we had from 2000-02 could easily wipe out a decades worth of gains.

Still, the stock market has been better over the last 10 (7%) an...
