Surreal Represent of Memory
Formed in Neural Mechanism
of Human Brain

In the field of neuroscience, over the past half-century, significant breakthroughs have been made in understanding the “biological mechanisms of memory”.

Perceptions of current situation are mapped into mental representations through the visual system and other sensory modalities, transmitted and stored between neuronal cells. As time passing by, the formation of new synaptic structures assist to turn short-term memory into long-term memory, drifting from the prefrontal cortex to the hippocampus and other cortical regions.

The scenes in memory are not alway, or always not, faithful to the reality. On one hand, when visual perceptions—composed from the fragmented information of numerous visual cells—is processed in the brain, elements such as human and environment are analyzed in varying levels by different brain regions. On the other hand, our attention would act as a filter, subjectively focusing on certain aspects of the objective world and enhancing the resolution of specific information. Furthermore, the emotions, triggered by the event, may also influence the formation and transmission of various microchemical substances between neural cells, eventually affecting both the content and persistence of the memory.

Thus, when we try to recall a specific moment from the past, the scenes that emerge in our minds fascinatedly differ from the realitic history: emotions, attentions, and contents are reassembled subjectively, creating a dreamlike memory reproduction that, though originating from reality, appears in a surreal form.

Increasing Accessiblity and Authenticity
in 3D Scanning Technology
for Reality Representations

The development of 3D scanning technology, from photogrammetry to recent Gaussian Splatting, has evolved from only accessible with professional scanning equipment to common devices like cameras and smartphones, also achieved in faster calculating speed and higher precision.

This improvement of speed and accessiblity us to capture any random moment into high-quality 3D scenes without intrusion on the events' authenticity, offering great potential for memory recording.

When combining real-world 3D scanning with virtual environments in game engines, this hybird technical method allow us not only represent the memories in the realistic way, but also reconstruct them in a “surreal state”, aligning with the level of individual perceptions. We could now visualize the invisible scene generated in neural activities, and more thrillingly, enable the shared revisiting of those memories between physical objectivity and emotional subjectivity.
