Fabien Benetou's PIM | Content / WikiBrainMapping

Principle

Solution

Use the structure of the wiki (through PmWiki:PageList and PmWiki:Category ) associated with actual brain areas associated with specific functions to generate a realistic visualization (using VirtualReality#Aframe ~~Processing#ProcessingJS~~ , thus also JavaScript).

The initial mapping could be naive, e.g. all pages in one location, the hyppocampus, then over time moved to more specific areas. This process would emulate neuron migration and specialization.

Current mapping

Area	Pages
Frontal lobe	Xmaswishlist
Visual cortex	Wiki.3DVisualization Wiki.Visualization Tools.OpenCV
Hippocampus	Wiki.MemoryRecipe

Not yet visualized, from WikiBrainMapping.Map. Could also use vatelier:Demos/InWikiAframeEmbedding in order to avoid edition outside the wiki.

Overall consequences

reconsider learned material including TreeOfKnowledge#Chapter7, HTM, neural networks in general and own ideas including Mind, Cognition#Thinking through such a much "simpler" representation
- even social distributed cognition
- also Seedea:Content/Newconcepts#InformationGeometry and its few links in Mathematics

Bigger picture

This visualization itself could be part of a larger visualization, e.g. applying OwnConcepts#Epistemotaxis by representing the individual and his or her PIM not as an entity changing itself but rather as an entity changing itself by moving within an environment.

Previous solution

This relied on a flat view, obsolete now thanks to pervasive efficient 3D and even VR on the web.

Hyperbolic projection

Consider a projection in hyperbolic geometry that maps the cortex gray matter, thus mainly outer layers, to a 2D plane mostly without white matter wiring.

potentially inverse hyperbolic tangent atanh()
- consider an iterative process or fractals for the convolutions and/or developmental aspect
- eventually start the other way around, apply tanh() to a 2D surface and compare with an axial view of the brain
explore instead Monica K. Hurdal's 2001 work on Modeling and Creating Flat Maps of the Human Brain
- dipole source localisation seems close to techniques learned during LImagerieCerebraleDansTousSesEtats
- Quasi-conformally flat mapping the human cerebellum, MICCAI 1999
- co-author with details on circle packings
- poster
the other way around, applying the invert model to a corresponding 2D map
- generate the exobrain (cf ObjectsExoBrain) or neo-neo-cortex (mentionned in MecaMind and WithoutNotesMay10#MichaelGoardEmilyJacobs and earleir discussions) mapping as a 3D model (or >3D, e.g. displaying time partly through the editions using Visualization#timeline) as capping over a 3D brain

Description of the followed process

find the 2 brain sides as existing flat rendering
1. from WithoutNotesMay11#BrainFlatMap
2. http://www.math.fsu.edu/~mhurdal/research/images/visman/vhrfull_er_an.jpg
convert to SVG http://inkscape.org/doc/tracing/tutorial-tracing.html
load into ProcessingJS
1. done using shape()
overlay place corresponding areas
fake vertical stacking of edits via shifted positioning
1. drawing a line then adding points instead of rectangles might improve readiblity
2. an animation could also add the content of the edit and thus represent the construction of the wiki as a set of successive
  1. which would only be partly correct since re-organization has been done and this without diff (e.g. moving a page)
