  • Abstract
  • Look Inside

1. ECoG. EM. EK and respiration curve were recorded before and after cerebral applic- ation of chelators by subdural injection in rabbit.

2. Following 10 chelators were used, (a) ED TA, (b) CyDTA, (c) NTA, (d) Na-Citrate, (e) K-Oxalate, (f) Oxin, (g) INAH, (h) o- Phenanthroline, (i) Gluconic acid & (j) EN.

3. Remarkable repeated spike bursts were observed for a long time without exception, after application of small amount of more active chelators (i.e.(a)……(g)).

Spikes were slightly or never observed when used less active chelators (h) (i) (j).

4. From these results we concluded, the grade of spike bursts run parallel to the chelate activity (its intensity and range) of chela- tors.

5. So we assumed, the deprivation of bound metal with brain-ligands provokes the re- markable long lasting spike bursts on ECoG.
