! 7 Sept. 2006: start with integrate_tuftRSXX.f from isoldeepVFOK, and ! add GABA-B c 31 March 2005: lower axonal gNa density and shift gNaF rate functions c 4 Nov. 2003, modify layVtup.f as integration program for layer V c tufted RS pyramidal cell, for use with groucho.f c20 May 2003: adapt non-tufted RS layer 5 cell, layVrsp.f, to tufted c layer 5 cell - should be either RS or IB, depending on params. c Total number of compartments = 61, axon 56-61; 18 levels; level 0 = axon. c 14 May 2003. Copy program from Rose and modify for mpi. c 19 June 2001. Taken from scortpd.f. Parallel. c 19 June 2001: layer V RS cell with "thin" dendrite, no apical tuft. c See Kim & Connors, Mason & Larkman. c 44 SD compartments, 6 axonal, total 50. c 5 basal and 6 apical oblique dendrites, each with 3 compartments. c 10-compartment apical dendrite, no branches (apart from obliques) c 13 April 2001, version of scortp.f, for looking at dendritic activities. c 7 April 2001, parallel version of scort.f c 30 March 2001: layer 2/3 pyramidal cell, with geometry (as much as c possible) from Guy Major thesis; start with tcr.f. c Total 74 compartments: 6 axon. 8 basal and 3 oblique dendrites, each c with 3 compartments: apical shaft and branch; 8 3-segment pieces in c the "apical tuft". c Revised tcr.f, using modifications developed in short.f c 22 Feb. 2001: alter persistent gNaP to have lower threshold and c 1st power activation; in addition, try increasing activation c threshold of fast gNa, as per Parri & Crunelli 1998. c 25 Jan. 2001, single TCR cell, modification of nrt.f c TCR cell has 10 short dendrites, each with 13 compartments. c Soma is compartment 1; axon is 132-137, with structure as in c nRT cell model. Each dendrite has 2 layers of trifurcations. c 28 Dec. 2000, begin converting interneuron program to nRT cell. c Soma will be comp. 1. 4 equivalent dendrites, each with 13 comps. c (so 53 SD compartments). Branching axon with 6 compartments - 59 c compartments in all. Try one integration program for whole structure. c Currents: leak, fast Na (naf), persistent Na (nap), fast DR (kdr), c A-current (ka), K2 current, M-current (km), C current (kc), AHP c (kahp), T-current (cat), high-thresh.
