In neuroscience, this is called the Hebbian principle

like a collage made from fragments of photos.The brain has to juggle a sea of thousands of electrical signals getting them all to their destination at precisely the right time.When you look at an object,thousands of neurons in your posterior cortex fire.
These neurons encode various characteristics of the object:
spiky, fruit, brown, green, and yellow.This synchronous firing strengthens the connections between that set of neurons,
linking them together into what's known as a neuronal ensemble,
in this case the one for pineapple.In neuroscience, this is called
the Hebbian principle,neurons that fire together wire together.
