  Procedure for localizing T-current in distal dendrites

	- Thalamic RE cell reduced to 3 compartments (re3)
	- currents must be localized everywhere

	first parameter: proximal conductance (soma)
	secnd parameter: medial conductance (proximal dendrites)
	third parameter: distal conductance (distal dendrites)

----------------------------------------------------------------------*/

proc localize() {

	soma.gcabar_it2 = $1			/* SOMA */

	dend1[0].gcabar_it2 = corrD * $2	/* PROXIMAL DENDRITE */

	dend1[1].gcabar_it2 = corrD * $3	/* DISTAL DENDRITE */
