I’m a big fan of unsigned_algorithms (link to jpeg.store), an NFT project on the Cardano blockchain. The project is unique because it is the first generative art project on that chain. By generative I mean that the code to make the image is what is stored on the chain. I’ll explain.

Often with NFT art, the blockchain is merely recording the location of a jpeg image. With unsigned_algorithms however, there was an ingenious mechanism introduced where the first NFT of the series is an equation. Then, each subsequent NFT is a set of parameter values that get run through the equation and thus produce a unique image. When you buy one, you are the proud owner of a set of parameters only! with a representative jpeg ‘along for the ride’ to show your result from the equation.

unsigned_algorithms use a small set of rules that involve a blend of line and color forms as shown below. There can be up to six properties in this project. I was intrigued by the patterns and the sense of calm that was generated when gazing on these images.

unsigned_algorithms

It meshed well with my understanding of the visual cortex, an hierarchical neural structure of the human brain that performs pattern recognition. There is an analogy to be discovered about the physical configuration of the pattern recognition neurons and the patterns they are designed to perceive.

This connection fascinates me. I started to develop a theory that the basic patterns of the unsigned_algorithms and their particular gradient colors along with unusual, yet-again, very basic symmetries, served to more or less provide the visual cortex with exactly what it was built to observe. By providing the pattern in an easily digestible format, so to speak, then the cognitive work being done by the brain is reduced.

Another level of ‘work’ reduction is realized by unsigned_algorithms being instantly recognizable as abstract art. When we know that the image does not need to be interpreted for rational meaning, it reduces cognitive load and the viewer tends to enter a more receptive, relaxed state.

I intend to stimulate each of the neural structures in accordance with their physical configuration, which reflects the pattern they are perceiving. The artwork is providing a basic set of patterns to be recognized by the V1, V2, V3, neurons while the ‘workload’ is reduced, potentially creating a cleansing sensation roughly like hosing out a screen — where the screen is your neural network and the water is stimuli from the art.

I asked ChatGPT to help me discover prompts that could create a work of art specifically designed to ‘exercise’ these basic visual centers of the organic human brain. First, I asked if ChatGPT understands my intention:

Certainly! It seems you’re aiming to create an analogy through viewing art that is specifically designed to stimulate the visual cortex in a particular way. Allow me to describe this process more fully:

The analogy you’re seeking to manifest revolves around the concept of harmonic resonance between the structure and function of the visual cortex and the visual stimuli presented through art. By intentionally designing the art to directly stimulate the visual cortex, you aim to create a metaphorical alignment or synchronization between the neural recognition structures and the patterns within the artwork.

Through the carefully crafted composition of the artwork, you aim to engage the visual cortex’s hierarchical structures by incorporating specific patterns and elements that are known to trigger recognition responses. The inclusion of basic recognizable shape patterns, such as horizontal, vertical, and angled lines, provides a foundation for activating the corresponding neural pathways in the visual cortex.

Furthermore, by introducing an arc or repeated curve, you add a complementary element that enhances the richness and complexity of the visual experience. These curves can create a sense of continuity, flow, and organicity within the artwork, allowing for a deeper connection with the viewer’s perception.

The choice of colors becomes an essential aspect of this analogy. By adjusting colors using gradients and patterns of contrast, you aim to create a novel yet easily graspable visual experience. The colors should be carefully selected and arranged to harmonize with the recognition processes of the visual cortex, evoking a feeling of resonance and coherence within the neural structures.

Ultimately, the viewing experience of this art is intended to create a sense of relief and pleasure. By aligning the patterns within the artwork with the neural recognition structures, you aim to minimize the cognitive effort required for pattern recognition. This reduction in cognitive load can lead to a feeling of relief, as the visual cortex efficiently processes and recognizes the presented patterns, fostering a sense of harmony and satisfaction in the viewer’s perception.

By manifesting this analogy through art, you aim to create a unique and engaging visual experience that directly stimulates the visual cortex, fostering a profound connection between the neural structures and the artistic representation.

I hope this description provides a more comprehensive understanding of how you are seeking to manifest the analogy through viewing art designed to stimulate the visual cortex in a specific way.

So, the first run through MidJourney, a text-prompt to image service, with the suggested prompts by ChatGPT gave a fairly predictable set of results.

An engaging abstract composition featuring intersecting horizontal, vertical, and angled lines, with a prominent arc or repeated curve. The bright and unique colors are adjusted using gradients and patterns of contrast that are symmetrical in simple novel ways yet easily grasped.

and another nice take…

Same prompt as above with more lovely results.

So, not terrible and not great. The unsigned_algorithm still holds its ground by comparison, in my opinion.

Then I added the entire ChatGPT assessment about “carefully crafted composition” through “activating corresponding neural pathways” and got this result:

You can see that MidJourney knows the words “neural pathway”.
Another version

This one feels a bit more effective:

Closer and closer

These results are getting more interesting. I will continue this exploration to creating the precise set of image-rules that will produce a cleansed effect in the viewer. By cleansed, I mean that energy was dumped down each neuron in a pattern detection sequence such that all ‘kinks in the hose’ or ‘sticky spots’ are run through.

More to follow… Next I’ll be looking at how African savannah and seascape influences the cortisol level. I believe these vistas are hardwired in our cognitive space somewhere.

Please gaze at each of the generated images, and let me know if they produce a profound sense of calm, in the comments below.
