Why either / or?
Seems neither to me.
"thinking" may have to do with "values" and "meaning", known to be
related to changes in activity of neural ensembles in cortical
polymodal association areas. Seems to me more like "resonance",
orhcestral music/musicians.
Neverhteless, calculations would fit in at another level: IPSPs and
EPSPs.
