Sketchpads In and Beyond the Brain

摘要: A model of human cognition is presented in which peripheral sensory images are selectively enhanced by corticofugal pathways. The same processes also generate quasi-sensory mental even the absence stimulation. This inversion forward processing can come about through hillclimbing algorithms or a type Hebbian synaptic facilitation I call inverse learning. neural mechanisms that enable us to simulate actions and evaluate alternative scenarios, described as internal sketchpads.
