What is brain metabolic activity?

Answer 1

The relatively high preservation of cortical metabolism in this patient defines the first functional correlate of clinical– pathological reports associating permanent unconsciousness with structural damage to these regions. The specific patterns of preserved metabolic activity identified in these patients do not appear to represent random survivals of a few neuronal islands; rather they reflect novel evidence of the modular nature of individual functional networks that underlie conscious brain function

Answer 2

our thought patterns are based on electric impulses and chemical reactions
