The saying "It's a jungle out there" refers to a competitive environment in which you'd better hone your skills if you hope to survive. And you'd better do what you can to keep a roof over your head, food in your belly, a leaf on your loins, and a mate who'll help pass on your genes to the next generation of jungle Jims and Janes.Distinguished professor and cognitive psychologist David Rosenbaum takes this metaphor of surviving in the wild and applies it to the competitive arena within the brain. He argues that the overarching theory of biology, Darwin's theory, should be the overarching theory of cognitive psychology, the science of mental functioning. He explores this new and intriguing idea by showing how neural elements compete and cooperate in a kind of inner jungle, where only the fittest survive.
