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

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…

Greenlight: "In Q4, Our Longs Went Up Less Than The Market And Our Shorts Went Up More"

2019 was a very strange year for the market, one in which stocks were up almost 30% despite no earnings growth and only multiple expansion, and yet not a single popular strategy worked. As a result, it was also an extremely painful year for hedge funds who were up for the year, but once again failed to catch up to the risk-free benchmark, the S&P500, and in fact, this was the 10th consecutive year in which active management underperformed the cheapest possible market investment, the S&P500 itself (and explains why there was a record-matching 8 consecutive months of hedge fund outflows in ...

Hang Seng Index Double Topping At 2007 Highs?

Could the Hang Seng Index be “Double Topping” at its 2007 highs? Possible, yet not proven!

The Hang Seng Index attempted to break above its 2007 highs at (1), only to see a key reversal pattern take place the following month.

After the reversal pattern, the index has created a series of lower highs, just below falling resistance.

So far this month, the index is attempting to break above falling resistance, where it could be created a bearish reversal monthly pattern at (2).

What would it take to prove that a double top was i...

SP500 Kitchin Cycle Review

The biggest known news date in the next 18 months is the US Election. The biggest unknown news date is when the US believes it is in a economic recession.

The Kitchin Cycle is still working.

We must conclude the major 900 period low is now in, and we are now in a up swing, which may top out ate 2020 or late 2021. Any future top out may only generate a 10% to 20% correction, of course this can be deemed very mild. This is expected, but the expected does always play out. 

Rolling the dice to get '7' does not always work. Post US elections seasonal's aligned with a poor start of the decade seasonal trends, add on high global recession risk, add on a stock market slump tends to occur in the years ending 9,1,2,3,4 (like 1973, 1...
