reflects the construction of experientially-correlated "biological
mass" [AoK, Ap5], which, further, discloses the 'inappropriateness'
of biochemical 'intervention'.

"Biological mass" derives in - is mapped to - experience.

Biochemical 'intervention' is not.

Do the latter =without= addressing experiential factors, and what one
ends up with is a "supersystem" having 'fractured' functionality
because the experientially-mapped "biological mass" remains extant
within the nervous system involved.

This's definitely some of what's involved in instances of
chemically-induced interactive violence.

Generalized communication of understanding of how nervous systems
process information, of course with commensurate Learning with
respect to such within individual nervous systems, will go a long way
toward ameliorating the difficulties inherent.

calculated the

| 27 healthy controls.
| Analyses showed that, of all the monoamine metabolites, CSF MHPG
was the strongest

| Altogether, the eight predictive variables - CSF concentrations of
| MHPG, 5-HIAA, gender,
| the bipolar/unipolar distinction, age, body height, and Hamilton

|  xplained 56% of the total variation in ABMS, with MHPG in

| "Our findings indicate that CSF concentrations of MHPG in severe
| treatment-refractory affective

| irrespective of age, gender, uni- or
| bipolarity, and current severity of the illness," the team writes
in the

| Thus, the involvement of norepinephrine turnover in the long-term
| of affective illness is a
| likely reality."
