External preference for pattern matches internal brain structure?

Note, I've been quiet for while, realize....it's cause I'm busy working something out as opposed to goofing off.  Am at the McColl Center in Charlotte, NC.  Working with the Neurology dept of the Medical Center.  More on this soon.

I'm trying to sort out why certain proportions and rhythms strike a positive response.  And saw a short reference to the reason we prefer certain patterns -- the example was when people buy a pick-six lottery card, they tend to choose a range of numbers that have certain spacing and are not very random.

Rarely will people choose 6 successive numbers, even though the odds are mathematically equivalent to any other 6 numbers.  The suggestion was that the choice of numbers and the pattern has some relationship to the structure of the brain.  Not unlike a fibonacci sequence, there is a mathematical progression that is organic and frequently repeated in nature.

Thus -- our external preference for pattern matches our internal structure.

If you see anything along these lines, send me a note.  I'm sorting through articles that are written much like this....

"In brain networks, a structural motif may consist of a set of brain areas and pathways that can potentially engage in different patterns of interactions depending on their degree of activation, the surrounding neural context or the behavioral state of the organism......We compare the motif properties of real brain networks with random networks and with networks that follow specific connection rules such as neighborhood connectivity (lattice networks). We identify some motif classes that occur more frequently in real brain networks, as compared to random or lattice topologies. Second, by rewiring random networks and imposing a cost function that maximizes functional motif number, network topologies are generated that resemble real brain networks across a broad spectrum of structural measures, including small-world attributes."

Do we crave the staccato beat of the internet?

For a long time I’ve thought certain visual patterns talk to our brain in a way that is comforting, reassuring and familiar. By adult-hood our mind has spent some twenty million minutes visually taking-in, resorting, recalling, recollecting, dreaming and making up images.  Somehow those images all have a distinctive underlying abstract pattern and visual rhythm -- best comparison would be the cadence of a paragraph of prose or the underlying beat of a melody.

Well past puberty, the brain is learning and developing procedural and semantic memory.  Muscle memory, the 10,000 hours rule, all the studies that explain the plasticity of the brain point to the idea that we wire our brain through repetition.

So what does the thousands of hours and millions of minutes of digital media mean to our brain, do we now crave the staccato beat of the internet?  Do we get a dose of serotonin when the visual rhythm matches the pattern we’ve grown to love and anticipate?

After searching online this morning for neurotransmitters and visual pattern, I found….

A research team from the Cardiff Brain Research Imaging Centre (CUBRIC) put subjects into an MRI scanner and recorded their brain activity using MRI and MEG technologies while showing them different visual patterns. They discovered that a person’s brain produces a unique electrical oscillation at a particular frequency when a person looks at specific visual patterns. This oscillation frequency is mainly determined by the concentration of the neurotransmitter GABA in the visual cortex of the person’s brain. The more GABA was found to be present, the higher the frequency of the oscillations.

Leading the research was Professor Krish Singh from the Cardiff School of Psychology, who said - “Using sophisticated MEG and MRI brain imaging equipment, we’ve found that when a person looks at a visual pattern their brain produces an electrical signal, known as a gamma oscillation, at a set frequency.

"In effect, each person’s brain ‘sings’ at a different note in the range 40-70 Hz. This is similar to the notes in the lowest octaves of a standard piano keyboard or the lower notes on a bass guitar. Importantly, we also found that this frequency appears to be controlled by how much of an essential neurotransmitter, GABA, is present in a person’s visual cortex.”

Serotonin and the sense of well-being from art objects

Mostly we ignore ourselves, I read recently that people who get cochlear implants as adults (to enable hearing), have enormous difficulty tuning out the deafening sound of their own heartbeat. We’ve trained our brain to ignore it.

Do we pay attention to our mood and odd factors that affect our appetite, ability to sleep, memory and general sense of well-being? Serotonin is at the root of this, we all know anti-depressants are ‘serotonin reuptake inhibitors’ – meaning they slow the rate of deterioration and keep serotonin in the system longer. Although there is more doubt that these actually work outside severely depressed individuals. Nonetheless, we’ve heard of Serotonin.

Interestingly Serotonin is mostly found in our gut. While Serotonin is a neuro-transmitter it’s not in our brain, 80% is in our gastro-intestinal tract. The production of Serotonin is shockingly complex – connected to not just body chemistry, but food intake, with an inverse relationship to other neurotransmitters, like Dopamine. But the release of Serotonin seems to be triggered by positive events, such as finding food and eating it. I’m hunting for the connection of Serotonin to art, and the biological urge to find comfort in visual objects. Is Serotonin released when we find art objects or ideas we like?

Imagining a predictive model of aesthetics

Within my lifetime, I think science will understand why your brain likes what it likes. Not only neuroscientists, but marketers, advertisers, and designers will all employ brain scans to anticipate preferences, catch our attention, design packaging and pattern our surroundings.  It’s already happening, but the precision and accuracy targeted at every individual is going to be amazing.

I've developed a hypothesis -- I think beauty or the sense of great comfort from art is related to the viewer’s early experience and the desire to recover something recognizable. Not at the literal or narrative level of memory, but where pattern operates like music, and provides a rhythm that feels like a familiar recollection at the level just below consciousness.  I think science will find attraction and desire are based on brain fluency, which is wired from the cumulative stimulus of individual life experience.  By extension, I believe each of us has something like a ‘genome of sensory preference’, which could be mapped. And eventually it's possible a predictive model of aesthetics could be built for each of us.
