Do we know the first, or at least possibly the most influential, occurrence of zombies targeting humans for our delicious brains?

And do we know why they go for that organ specifically?

Because braaaaaainss – Valorum Mar 10 at 8:18
@Richard you make a good point. – Daft Mar 10 at 8:48
Zombies are particularly fastidious. Your brains are the farthest thing from your feet, which zombies find to be unquestionably the most disgusting portion of their food. Feet! Ewwwww! Brains? YUMMMMMMMM!!!!!! :-) – Bob Jarvis Mar 10 at 14:25
Because brains is the most important meal of the day. Because brains is good food. Because 7 out of 10 doctors recommend it. Because brains help a body grow in 8 different ways. Because they are doctor recommended and mother approved. Great taste, less filling. – General Decline Mar 10 at 15:49
@RickHenderson As someone who does not watch a lot of the Simpsons and who lives in Asia, I would tend to disagree. The Simpsons' portrayal of Zombies was already well established, otherwise the reference to brain eating would be difficult to comprehend. Further, modern non-US movies, TV Shows and tropes follow the same portrayal and have followed it since before the Simpsons episode you quote. – The Wandering Coder Mar 11 at 1:11

In regards to why the zombies feed on brains, there is an official explanation is a quote from Return of the Living Dead’s writer and director, Dan O’Bannon, who suggested that the undead felt the need to feed on the brains of the recently living because it somehow made them feel better by easing their pain.

Night of Living Dead (1968, directed by George A. Romero) is the first movie about modern day zombie understanding in the history of film making.

While it’s true that zombies have been around in various forms before the release of Night of the Living Dead in 1968, Romero’s film is largely considered to have introduced the concept of the modern zombie to the world and almost all media involving them draws from his film in some way.

Although Romero is noted as the source for many of the common zombie tropes, shambolic movement and a hunger for human flesh being the most prominent, zombies don’t actually eat brains in any of the six “Of the Dead” series of films he directed. In fact, Romero himself has no idea where the brain-eating idea came from and in a 2010 interview with Vanity Fair, when asked about the link between zombies and brains, Romero very bluntly explained that:

Whenever I sign autographs, they always ask me, “Write ‘Eat Brains’!” I don’t understand what that means. I’ve never had a zombie eat a brain. But it’s become this landmark thing.

The origins of the “zombies eating brains” trope didn’t actually appear in media until well after Romero’s film debuted in the 60’s, first being featured in the 1985 movie, Return of the Living Dead.

After the release of Night of the Living Dead in ’68, Romero and his co-writer, John Russo parted ways and reached the agreement that Russo would retain the rights to the “living dead” suffix whilst Romero agreed to use “of the dead” in any subsequent media he produced.

Avid fans of the zombie genre have tried to expand on this reasoning by asserting that zombies eat brains and guts because of the high levels of serotonin they contain, but this suggestion was never confirmed by other creators and directors.

Very good answer! – Daft Mar 10 at 10:29
You should cite gizmodo for this answer. This part important: The Simpsons are believed to be the main culprit. The 1992 classic Treehouse of Horror segment Dial Z for Zombies, which itself was a spoof of Return of the Living Dead is the one of the earliest pieces of media with the exception of Return of the Living Dead itself to feature brain eating zombies. – James Mar 10 at 13:14
@James My source is different. And it seems gizmodo shares my source as well. Look at the datetime tag of their post. Also, I didn't include The Simpsons part because they didn't create flesh-eating zombie concept. They simply used what the populer culture was talking about. Which is brain-eating zombies. You can also see (above answer) how original creators thought about all of this. – apollo Mar 10 at 14:20
TVTropes suggests Return of the Living Dead as the source: – Tim B Mar 10 at 17:32
@Octopus he does include "modern day zombie understanding" in the post now does that make it better? Detailed knowledge of the early movies is beyond me. – Rick Henderson Mar 10 at 20:45

White Zombie (1932) and I Walked with a Zombie (1943) are the more traditional zombie movies. The zombies in these are based on the traditions of Haitian voodoo. The Romero zombies were introduced in The Night of the Living Dead (1968) and are more like reanimated ghouls than the mindless slaves of the Haitian tradition.

Night of the Living Dead zombies killed and ate victims but did not have a tropism toward brains. Brain-eating was introduced in the parody Return of the Living Dead (1985).

You can call it a parody but I found it introduced some interesting ideas -- explicit zombie sentience for one thing. – Jeff Mar 13 at 9:08

According to TVTropes and the Living Dead Wiki the most likely source is "Return of the Living Dead", specifically the character Tarman.

the Tarman climbed out and went to look for fresh brains instead. However, since Frank and Freddy were knocked out, they never knew Tarman reanimated. They assumed he melted when he hit the air. He actually spends most of the film hiding down in the basement until Tina goes down there. He snuck up behind her and attempted to eat her brain. Luckily for her, she hid inside of a locker but since Tarman was desperate for her brain, he tried to rip off the door with a winch. While she was trapped in the cellar, the other punks heard her screams and ran through the door and down the steps. In the process of finding Tina, Tarman got a hold of Suicide and devoured his brains.

Welcome to SFF:SE. Here, we prefer answers to be a little less speculative, at least where they touch on real-world questions. If you could find any record of the creators of the works in question making such a question, it would improve your answer greatly. – Politank-Z Mar 13 at 21:19

Zombies don't have brains themselves. For an unknown reason they retain electric stimuli that move their limbs. Even a small electric charge is sufficient to provide them energy to move. It is a well known fact that the brain is the source of electromagnetic waves. Therefore zombies are attracted by this source of electromagnetic waves. It is well known that rats are as well attractecd by high voltage cables chewing them, even sharks tend to bite submarine communication cables, due to the low frequency "noise" emitted by these cables. This is the scientific explanation to zombies being attracted to brains.

Yes, like @amaretto I am going to have to disagree with your assertions. – scifiaddict Mar 12 at 23:59
@amaretto: they’re clearly not tall enough to reach them. – Paul D. Waite Mar 13 at 0:20
Power lines have different wave frequency, not every animal "hears" them. Zombies are attracted by brain wave frequencies. It is like dogs who can hear very low/high frequency sound. I know these signals are weak, but this should be subject to medical studies, provided someone get a zobie to study. – jmagave Mar 13 at 0:27
As far as I noticed this SE is about fiction and fantasy, of course zombies as described in sci-fi is... sci-fi. I simply tried to answer the question: why they go for that organ (brain) specifically? – jmagave Mar 13 at 14:10
@jmagave - We're not looking for answers based on your own headcanon or fan-fiction. We'd like something that reflects the decisions made by earlier writers/directors in the genre. – Valorum Mar 13 at 21:33
