Well, seeing as how we were so totally dumb back in the stone age of course we bought "Spock's Brain" as being totally plausible.
OK, I'm kidding.
Seriously even though I was 8 at the time I remember it very well because it was a weird mixture of total malarkey yet kind of eerie. When McCoy said Spock's brain was gone, I remember it was shocking yet I almost laughed, it bordered on ridiculous.
So when I see Spock walking around with that gizmo on his head, I knew it had definitely crossed that border into ridiculous but still it was strange how it was Spock yet not Spock.
Maybe, maybe I could buy that alien thingy giving McCoy the temporary knowledge to reattach the brain. But when Spock starts directing McCoy and immediately sits up after the operation, I'm going "Oh c'mOOON!!" and throwing things at the TV.
Actually I didn't throw things at the TV, it was a brand new color TV, our first one. My dad had gotten a much better paying job earlier that year and one of the first things he bought was that TV.
But yeah that ep was quite ridiculous but you gotta look at it as a tall tale, a total yarn. They can still be entertaining or not. This ep kind of falls on the entertaining side although by the time Spock is directing the operation and sitting up, my suspension of disbelief was DOA.

I agree. That ending has to be one of the most absurd wrap-ups in TV history. The entire of notion of Spock directing his own surgery is complete absurd BS! But, I also think that was a product of the times. Back then, everything had to be cleanly and neatly resolved by the end of the episode.
Something like that now, might have had lasting repercussions at least for a couple of episodes. Just look at the character of Picard changed after Best of Both Worlds. It took him a couple of episodes to get over that...at least.
But even so...I don't think having Borg implants or your brain removed and restored is something one would just get over in a few minutes -- I think something like that would have been a major traumatic event for Spock. Or at least it should have been.
