It would make sense that any information is stored as a key-value pair in the brain. In this case, the key is the sensory input, and the value is the type of surface that is being touched.
Could the simplistic key-value pair work in creating more complex systems? perhaps it does, if keys are complex input structures which be divided into more keys in a tree-like fashion.
- pjc50 8y agoI don't think it's established that either "keys" or "values" exist in the brain. It's more "stimulus-response", where similar stimulus produces similar response. There's a nonlinear classifier going on which tends to create categories for us, but it's definitely possible to produce cross-category stimulus.
- eli_gottlieb 8y agoThere isn't a classifier in the brain, and there certainly isn't a key-value store. The brain mostly runs the sensorimotor systems based on top-down Bayesian prediction, not bottom-up classification or regression.
- axilmar 8y agoThe way living organisms behave certainly points towards a simple key-value store, where key is the current experience and value is the response.
- eli_gottlieb 8y agoScientifically speaking, no, that's not even remotely true. What on Earth gave you that impression?
