wiki  Cortical minicolumn
 
contains 80 to 120 neurons  (vertical)
 
There are about <b>2 * 108  minicolumns in human</b>s    note:   100 * 2 * 108 =  20B neurons in cortex, perfect.
 
minicolumn diameter is  28 to 40 microns.  see calculations
 
FActs: <b> cells in 50 micron minicol all have same receptive fie</b>ld;
 
downward projecting axons in a minicol are abt 10 microns in diameter;
 
<b>one axon coming into thalamus reaches  100 to 300 minicolu</b>mns
 
<b>Number of fibers in corpus callosum is 2 to 5 * 108  perhaps related to the number of minicolum</b>ns
