3: Parent compartment (non-soma)
A non-soma parent compartment is that on a child branch immediately before the
branch point, i.e., it is compartment N on that branch. Such compartments follow
the same derivation as interior ones, except that the υ⅛+ι and α⅛+ι terms are replaced
by vparent,ι and aN, yielding

4: Parent compartment (soma)
A non-soma parent compartment is that on a child branch immediately before the
soma. Hence they follow the same derivation as interior compartments, except that
the Ufc+ι and ak+i terms are replaced by vsoma and a^, yielding
