Issues

The following is a list of issues to be examined as I explore the functionality of each field in the genetic structure of the brain lobe gene.

  1. Can brain lobes be switched on or off based upon the gene header details. That is, can different lobes be created for different genders and can lobes be turned on when a norn hits certain ages. Is there any useful benefit that can be explored if this functionality exists.
  2. What is the effect of overlapping brain lobes? If the (X, Y, W, H) values of a lobe cause a portion to overlap another lobe what affect does this have on the values of the neurones?
  3. Does the location of a brain lobe within the brain grid or the different height and width combinations have any affect on the functionality of a brain lobe? Does it affect dendrite fanout and migration for example.
  4. What does 'Mutually Exclusive' in the 'Data Copied to Perception Lobe' do?
  5. What is the effect of changing 'input gain hi-lo' on the 'Cell Body' page?
  6. Work out the exact affect of 'spread' and fanout in the dendrite pages. Draw a diagram showing what it does instead of that horrible textual description!!
  7. Determine if the 'shape' (W, H) of a lobe affects the fanout of the dendrites.
  8. Describe the functionality of STW and LTW of dendrites.
  9. Are the Min LTW,Max LTW, Strength, etc only used for randomly setting values of the dendrites at birth? Or do they define the minimum and maximums that can apply throughout the lifetime of the dendrite?
  10. Work out exactly what each setting for the migration rules of the dendrites means.
  11. Does migration of dendrites only occur when the cell is firing in all cases?
  12. Investigate and describe what all the values for a dendrite are (susceptibility, etc).
  13. Investigate how susceptibility works.
  14. Document what time span each number in the half-life sliders relates to.
  15. Write a program that demonstrates how STW, LTW, etc interact.
  16. Expand and refine the dendrite overview.

Issue 3

Yes the height and width of a lobe affects the original dendrite connections. The following image shows a source lobe of height 1, width 3 connected to a destination lobe with height 1, width 3:

Notice how the dendrite links are basically cell by cell. Cell 0 is connected to cell 0 and1. Cell 1 is connected to cell 1 and 2, etc. If the lobes are done as a 3x3 square we get more of a spread in the connections:

I've only filled in a few lines here. I really need a 3D diagram to do it justice! Image the two lobes overlay each other. Now each cell can connect to the cells to either side of it. So cell 5 in the output lobe is next to cell 5 and cell 7 in the input lobe so they can be connected. Cell 8 is next to Cell 4 so it can be connected, etc.

By changing the width and height of the input and output lobe you can adjust the initial spread of the dendrites - perhaps giving a wider spread than would otherwise have been done if it was one straight lobe. I believe it would also give more cell choices for dendrite migration as well.

Issue 4

Solved thanks to some pointers from a couple of anonymous tipsters. Information has been updated on the Brain Lobe page and the Perception Lobe Tutorial.
