The most-compelling reason to study, and comprehend the neuroscience stems
from the fact that "knowledge" with respect to "human nature" has been
accumulated only haphazardly over the course of the millenia. But because such
has been the familiar experience, such "knowledge", worthless as it is (as is
the case with the products of any random walk), never-the-less, becomes
encoded within the microscopic trophic (growth) modifications to the brain,
and from which arises what's been referred to as "memory", which,
subsequently, governs convergence upon behaviorally-manifested "choices". And
because it's been the case that such haphazardly-accumulated stuff.does govern
"what will be" behaviorally, behavior, itself, can only be commensurately
haphazard. Any reading of History bears all of this.
Into such, via the study and comprehension of Neuroscience, strides
Understanding, which displaces the randomly-accumulated stuff, and
simultaneously, the behavioral "craziness" that the Historians have documented
That's why the study of Neuroscience is Worth the "trouble".

The scans disclose underlying neural energy dynamics... where the work is
happening. When the scans are cross-correlated with the rigorous geometrical
order that exists within our nervous systems, and with energy-flow dynamics
within the external environment ("stimuli"), the way that the external
environment is represented within the nervous system, and the way that the
nervous system operates in the global energy domain, can be flat-out seen.
Such seeing requires the study, and comprehension, of Neuroscience... else one
cannot even recognize that there is a rigorously-ordered geomethr through
which everything is disclosed.
Note: the scanning techniques are modern extensions of much-older
single-neuron recording techniques, and somewhat-older array-recording
techniques, which, when the stuff of their many experimental papers is
cross-correlated, disclose the same stuff.

Any theory in Neuroscience is plausible to the degree that it incorportates
proven Neuro experimental results, discloses errors in experimental results,
and is in aggreement with cognitive, affective, and behavioral observation.
Any theory that does not, to the degree that it does not, is not a valid

See my opening comments, above. It's a matter of Life and Death on the scale
of Earth's whole population. ken collins
