I realise this is a weird thing to suggest, and society today is very different from then, (although, 'plus les choses changent, plus elles restent les mêmes'), but this has been preying on my mind recently, due to reading an article about brain research being carried out on adults (with their consent) decades ago.
When I was very wrong - early 60s - my sister and I were taken to a Birmingham hospital a few times to have electrodes placed on our skulls, and patterns were recorded. I remember it very well, even though I was only about two, because the whole thing was strange and scary to me. Later, my mum said it was to determine whether we were identical or fraternal twins (we're fraternal), so I know her permission was involved. Now I know there wasn't the access to the science that determines this type of thing today, but in that period would they try and establish twin DNA by measuring brain patterns? I very recently talked to my sister about it and, although she remembered it, she gave a different reason for it happening.
The reason I'm putting it out there is to see if anyone has had the same experience, or knows anything about it, and, if so, what reasons were given for it? Were we experimented on, and was my mum told the truth or lied to? I can't ask my mum any more about it, as she died in 2019.
