"The famous Poohsticks Bridge...
If you intend to play a game of Poohsticks at the bridge,
you'd better grab a stick along the way,
because the area around the bridge is usually plucked bare"

"The original wooden crossing on which the illustration is based – known as Posingford bridge, at Hartfield farm, Sussex – had fallen into disrepair by the 1970s.
It was carefully restored and reopened in May 1979 by Christopher Milne – the author’s son who inspired the character of Christopher Robin.
At that unveiling ceremony it was described
“as important a bridge as any in the world”.
The bridge was completely rebuilt in 1999."

Divergent thinking is a thought process or method used to generate creative ideas by exploring many possible solutions. It is often used in conjunction with convergent thinking, which follows a particular set of logical steps to arrive at one solution, which in some cases is a "correct" solution. Divergent thinking typically occurs in a spontaneous, free-flowing manner, such that many ideas are generated in an emergent cognitive fashion. Many possible solutions are explored in a short amount of time, and unexpected connections are drawn. After the process of divergent thinking has been completed, ideas and information are organized and structured using convergent thinking.

Sensory gating describes neurological processes of filtering out redundant or unnecessary stimuli in the brain from all possible environmental stimuli. Also referred to as gating or filtering, sensory gating prevents an overload of irrelevant information in the higher cortical centers of the brain. The pulvinar nuclei of the thalamus play a major role in attention, and filter out unnecessary information. Although sensory gating is largely automatic, it also occurs within the context of attentional processes. Though the term sensory gating has been used interchangeably with sensorimotor gating, the two are distinct constructs.
