What does high Delta mean?

[Guest guest]

I was wondering if someone could help me understand why a person would

have high Delta amplitude in eyes open, eyes closed and at task? When

looking at the spectrum it is consistently the highest amplitude band.

I wish I could remember the sources where I had heard it from but I

have gotten a couple of bits of information and am not sure how to

understand them. One is that delta is generated from the brain stem

and it correlates to trauma, one was that people with high delta tend

to be sensitive to others and their surroundings correlating with

empathy and social awareness (i.e., mental health professionals) and

the third is brain lesions.

Does anyone have any info on this or references I could check out?
