h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Once I've read an article describing a very cunning experiment
performed at UCLA in the 70's.Researchers attached some
common house plant to the EEG and left it alone in the room.
Two volunteers were asked to enter the room(one at the time)and spend one hour with the plant . Volunteer A was instructed to act agresive - shouting and cursing at the plant , breaking things etc. Volunteer B's role was to act nice. He spoke
softly, sang to the plant and moved about slowly. Three different EEG patterns emerged:one for no company, one for the presence of volunteer A and one for presence of volunteer B.
The plant was obviously showing some sort of response to a
human behaviour , but couldn't be asked, of course, to comment it. Than the reaserchers did something rather clever.
The plant was left in the room alone for a month. Than the volunteers returned and each spent one hour with the plant.Only,
this time they were instructed to abandon their roles and just sit
on a chair in silence. The moment each one of them entered the
room , plant's EEG showed the same individual pattern from previous stage of the experiment. In other words, the plant remembered them. It "knew" who they were as a result of their behaviour.
Could it be that a brain is some sort of interface or a monitor?Ancient Chinese performed brain operations and yet they didn't consider it to be the center of the mind.Brain role in more basic lifeforms is asigned to the stomach(solar plexus?)
and wise old Greeks considered brain as a heat regulator.Questions,questions.

The shepherd never meant for the sheep to open Pandora box.

yeah, but now we're in there, is it so bad to have a shufty about?
And can you prove we weren't meant to open it? Newton said the whole world is a puzzle from God, so let's have a fiddle...
