Abstract

Spectral changes upon death (global ischemia) were recorded in situ in cat cerebral cortex. A rapid signal loss of 10 ± 4% in the N‐acetyl resonance was observed (five cases), after which it remained constant for 1 h. For the first time signal changes are reported for low‐field resonances, which are assigned to adenosine/inosine and hypoxanthine.
