Visual High Speed Cortex Preprocess
Associative Cortex 6-12 hz Mem+Percep
A simulation of an image being preprocessed and then sensed, retained, and perceived
in a synchronous neural association network.
You can initiate perception from a square sample by clicking in the left Cortex Preprocess area.
You can change the sensory input to any image in the row of images below the simulation. Short Term memory settings affect image overlapping.
Click inside Associative Cortex area to see active pyramidal axon branches coming to a (yellow) active neuron, or branches emerging from an activated pyramidal neuron (hidden among dense groups of neurons).
Global Variables (like the size of the test sample) can be edited below, including the preprocess matrix which affects images as they load.
hi
The Challenge is to find where to click (sample) the left side image to produce the clearest image in the right side, and explain how you find the best sample for each of these 8 images - write me and I may send you a prize!
| General Note about changing images: If you change images faster than the short term memory effect, then expect some of the previous image to be recognized as well. The default is 3000 milliseconds (which can be changed below) so initially wait 3 seconds before changing the image after choosing or testing a image to prevent inadvertant cortical neuron activation by previous actives (the STM potentiation effect). |

Note: any recent images should be more accessible than those that have faded into completely inactive memory. In real life it is about 5 minutes. | 10000 | |||||||||
| Note: the test size is a square of so many pixels, 150 is default which is half of the width and height of the image | 150 | |||||||||
| Note: Reactivation threshold for resting Neurons eg. the number of (ARC protein) connected synchronous spine activations neccessary to re-activate a resting neuron - the higher this number, the fewer original associated neurons in the memory engram will be reactivated from a sample. | 11 | |||||||||
Note: Number of Thalamo-Cortical Feedback loop cycles more cycles enable more progressive neural reactivations for a more complete perception. | 5 | |||||||||
| Note: this affects the ephaptic field ring extent which is an unresolved biological constant in the 1/10th of a second time frame. Adjust this only once at the beginning of a session (page redisplay) - the positions of circular interference will change some of the synchronously firing pyramidal neurons that are involved in an associated memory engram. | 30 | |||||||||
| Note: the original greyscale is inverted as to negative grayscale image, this preprocess is applied to create a black and white version - anything darker than this threashold out of 255 is black and vice versa, note % grey has a logrhythmic character. | 50 | |||||||||
Preprocessing Matrix mask - click to change individual matrix cells - we are using this to remove large color filled areas
- values can be '-1' '0' or '1':

Other Global Variables should be changed only at the code level as they affect the amount of memory the page requires,
such as the number of branches capable of linking Cortical neurons per Pyramidal neuron (5000 in this version),
and the ratio of branching Pyramidal Neurons embedded in the Cortical Neuron Population (1 P per 5 C in this version).
Based upon 300x300 cortical neurons = 90,000 there are 18,000 pyramidals with 36,864,000 total connections in this demo
This demo implements hypothalamic suppression modelling during image selection which suppresses *TOPDOWN* current active mental events (i.e. the perceptive reflex content) and enables more refined subsequent focussed recognition. (Focussing involves suppression of reflex perception).
(*) % gross perceptive reflex reactivation is a number that compares the active neuron count after perception with the active neuron count when the image is first encountered, it is not a figure related to pattern correspondence - merely a gross activation figure. Additional activation will occur after learning several images and will be visible as screen hash, or dust in the background - indicative of cortical neurons of other engrams which share the same ARC protein spines.
