Is link-joy the next step in understanding how the brain works?

Brian Bayly has suggested the phrase link-joy to describe a three step process consisting of a "puzzle", "solution" and "hedonic" response.

"- repetitive visual patterns (wallpaper, friezes, colonnades)
- an intention and its result (use of physical
dexterity or skill)
- an expectation that is met (e.g. in music or
other rhythmic activity)
- aesthetic experience (external object resonating
with an agent’s internal concept)
- puzzle-solutions and insights
- any recognition (e.g. a familiar object or scene,
or a word heard or read)
- tidiness, matching how it is with how it should be."

"A Eureka moment has three components – puzzle, solution and hedonic response (elation etc.). Puzzle and solution come together in the association cortex and are immensely variable from instance to instance. By contrast, the hedonic response is subcortical and almost one-dimensional; how is it triggered? It is triggered by the relation between puzzle and solution, a good fit or good match, like the relation between two words that rhyme. In 1999 J.W. Fost proposed that serotonin is a crucial agent; here it is proposed that a frequency-jump initiates the serotonin causal chain, as energy shifts from 20 to 40 Hz or some such jump."

According to Bayly link-joy is often weak and unnoticed like breathing, but it is a fundamental way we think. We may experience thousands of mini-link-joy phenomenon every day.
