Introduction
Long before humans spoke their first words, the brain was already communicating through pulses, patterns, and rhythms. This “First Language” can be understood as a pre-linguistic, neuro-sensory system of meaning-making grounded in the body and brain.
Biosemiotics provides a framework for exploring this First Language by examining how rhythmic and geometric neural activity may function as foundational forms of communication and cognition.
1. Biosemiotics: Life as Sign Process
Biosemiotics is the study of sign processes in living systems. It proposes that all forms of life engage in semiosis—the production, transmission, and interpretation of signs.
These signs extend beyond language to include bodily signals, environmental cues, chemical gradients, and patterned behaviors.
According to Jakob von Uexküll, each organism exists within its own subjective world, or Umwelt, constructed through meaningful perception and interaction. Thomas Sebeok expanded this idea by proposing that semiosis is not simply a feature of human language but a defining characteristic of life itself.
This idea—that living is interpreting—allows the nervous system, and the brain in particular, to be viewed as a powerful semiotic system. It generates patterns of neural activity that can be experienced internally and communicated externally. This is where the First Language begins.
2. Neural Signs: The Semiotics of Temporal and Spatial Patterns
The brain does not communicate through static images alone. It operates through temporal codes and spatial activations. Neurons fire rhythmically, oscillate in synchrony, and form dynamic networks of excitation and inhibition.
Neuroscientists such as György Buzsáki have described this as a kind of “neural syntax,” in which brain rhythms—particularly alpha, theta, and gamma—help structure how information is encoded and transmitted.
At the same time, the visual cortex, particularly V1, can produce complex geometric activation patterns when stimulated rhythmically, such as through flickering light or internal neuromodulation.
These patterns can include spirals, tunnels, grids, and webs, forms that recur in reports of hallucinations, trance states, and ancient art. Within this framework, they are understood not simply as illusions but as expressions of the brain’s own geometric language, generated by the structure and connectivity of cortical networks.
3. Perception as Semiotic Activity
Biosemiotics interprets perception itself as a semiotic process. Sensory information is not passively received; it is actively interpreted by the organism as meaningful.
In the brain, this process is expressed through qualia—subjective experiences arising from particular patterns of neural activation.
Within this framework, these experiences possess semiotic structure. A spiral is not merely a shape; it may signify movement, emergence, or transition. A rhythmic beat may signify presence, heartbeat, danger, or ritual.
The First Language is therefore composed of biosemiotic signs that are both perceptual and symbolic. They emerge from the organism’s own rhythms and structures while potentially conveying consistent meaning across individuals who share a common neurobiological architecture.
4. From Internal Signs to Shared Communication
One of biosemiotics’ central insights is that semiosis can occur without words. Organisms, including early humans, can interpret signs and generate meaning before the emergence of spoken language.
The First Language emerges from shared embodiment: human brains are structured similarly and respond to many of the same types of patterns. This framework is used to explain the recurrence of geometric hallucinations across cultures and the appearance of similar symbols—such as spirals, lattices, and zigzags—in early cave art and modern visual neuroscience.
Rhythmic entrainment through activities such as drumming, chanting, and firelight flicker may also align brain states between individuals, producing shared biosemiotic experiences.
Collective states such as trance, ritual, and dance can therefore be viewed not only as social activities but as symbolic exchanges using the First Language. Rhythm and geometry can encode emotional, cognitive, and communal information.
5. Evolution of Symbolic Systems
As human cognition evolved, so did the ability to externalize and elaborate internally experienced signs. Within this framework, geometric forms generated in the visual cortex became the first marks on cave walls, while rhythms experienced in trance became early musical traditions.
Over time, these biosemiotic signs were abstracted and diversified, eventually becoming associated with phonemes, words, and grammar. Yet the underlying system remained—a deep, pre-linguistic layer of meaning carried through temporally patterned neural dynamics and spatially structured cortical maps.
This perspective aligns with the work of paleoanthropologist Genevieve von Petzinger, who documented 32 recurring geometric symbols in Ice Age European cave art.
It also resonates with Jungian concepts of archetypes—innate symbolic patterns recurring in dreams, myths, and altered states—and with embodied cognition theories that view bodily patterns as foundations of abstract thought.
6. The Brain as a Biosemiotic Organ
From this perspective, the brain can be understood as a biosemiotic organ: a system that generates, processes, and interprets signs through rhythmic and geometric codes.
This system operates internally as conscious experience and externally as symbolic communication. The brain is therefore both the site of the First Language and the mechanism through which later forms of language evolved.
The First Language was not primitive. It was rich, complex, and universal— a shared semiotic repertoire rooted in biology. Rather than being limited by grammar, it was structured by the dynamics of oscillation, resonance, and form.
Conclusion: The Legacy of the First Language
The idea of a First Language rooted in biosemiotic processes invites a reconsideration of the origins of meaning, communication, and consciousness.
Before words, writing, and narrative, there were rhythms and shapes—felt, seen, and shared. These patterns formed a language expressed by the brain and encoded in the fabric of life.
Biosemiotics provides a vocabulary for describing this language, while neuroscience offers a framework for understanding where and how it emerges.
Together, they suggest that the origins of human symbolic thought may lie not solely in the invention of speech, but in the shared, embodied experience of pattern and rhythm— the First Language that continues to echo through dreams, rituals, and art.
