! 17 Feb. 2003: TCR cell looks much better after adjusting gCaT distrib. per ! Williams & Stuart (peak in dendritic stems); also adjust gAR, which has ! signif. effect on number of fast spikes/LTS. ! 13 Feb. 2003: Diego Contreras felt old TCR cell showed too much attenuation of spikes ! in a burst, and too many spikes/burst at 10 Hz. Following changes undertaken: ! decrease gCaT density to 5 from 7.5 in layers 3, 4 ! shift mnaf -3 mV and hnaf -7 mV ! gKA density x 0.2 everywhere ! gKDR density x 0.45 axon, soma, level 2. !
