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…

Disney Did In 1 Day What Took HBO 4 Years: 10 Million Streaming Subscribers

Courtesy of ZeroHedge

Somewhere Netflix and Amazon video are sweating.

Disney announced today that Disney+ has reached a stunning 10 million plus subscribers just 24 hours after its launch yesterday in the U.S., Canada, and Netherlands; the figure surprised analysts who had expected a much slower rollout for Disney to reach that level, although let's just ignore that most of the new "subs" are only there thanks to one of the various free streaming offers (perhaps someone should launch WeStream).

Separately, Apptopia reported 3.2 million mobile app downloads in the first 24 hours, with an estimated 89% of mobile downloads in the U.S., 9% in Canada, and 2% in the Netherlands. In just one day, users spent 1.3 million hours watching it, Apptopia said, more th...

Is Bitcoin a Macro Asset?

 

Is Bitcoin a Macro Asset?

Courtesy of 

As part of Coindesk’s popup podcast series centered around today’s Invest conference, I answered a few questions for Nolan Bauerly about Bitcoin from a wealth management perspective. I decided in December of 2017 that investing directly into crypto currencies was unnecessary and not a good use of a portfolio’s allocation slots. I remain in this posture today but I am openminded about how this may change in the future.

Silver Testing This Support For The First Time In 8-Years!

Courtesy of Chris Kimble

Its been a good while since Silver bulls could say that it is testing support. Well, this week that can be said! Will this support test hold? Silver Bulls sure hope so!

This chart looks at Silver Futures over the past 10-years. Silver has spent the majority of the past 8-years inside of the pink shaded falling channel, as it has created lower highs and lower lows.

Silver broke above the top of this falling channel around 90-days ago at (1). It quickly rallied over 15%, before creating a large bearish reversal pattern, around 5-weeks after the bre...

Gold Gann and Cycle Review

Courtesy of Read the Ticker

Gold has performed well, golden skies are here again. In fact it has been a straight line move, and this is typically unusual and a pause can be expected.

It seems the markets are happy again, new highs in the SP500, US 10 year interest rates look to re bound, negative interest may soften. The US FED has reversed their QT and now doing $250BN (not QE) repo. The main point is the FED has stopped QT, and will do QE forever. The evidence now is the FED put is under market risk and the possibility of excessive losses do not exist. 

Point: If in future if there is market risk, the FED will print it's way out of it.
Subject To: In this blog view. The above is so until the amount required rocks confidence in the US dollar as a reserve currency.&n...

Today's Fed POMO TOMO FOMC Alphabet Soup Unspin

Courtesy of Lee Adler

But make no mistake, if the Fed wants money rates to stay down by another quarter, it will need to imagineer even more money.

That’s on top of the $281 billion it has already imagineered into existence since addressing its “one-off” repo market emergency on September 17. This came via  “Temporary” Repo Man Operations money, and $70.6 billion in Permanent Open Market Operations (POMO) money.

By my calculations that averages out to $7.4 billion per business day. That works out to a monthly pace of $155 billion or so.

If they keep this up, it will be more than enough to absorb every penny of new Treasury supply. That supply had caused the system to run out of money in mid September.  This flood of paper had been inundati...

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...
