The overall goal of this target article is to demonstrate a mechanism for an embodied cognition.In Piaget's classic "A-not-B error," infants who have successfully uncovered a toy at location "A" continue to reach to that location even after they watch the toy hidden in a nearby location "B." Here provide a formal dynamic theory and model based on cognitive embodiment that both simulates the known A-not-B effects and offers novel predictions that match new experimental results.The demonstration supports an embodied view by casting the mental events involved in perception, planning, deciding and remembering in the same analogic dynamic language as that used to describe bodily movement, so that they may be continuously meshed.

Now the phenomenon of global disappearance of amphibians has been scientifically established. Correlating rates of decline with environmental factors should reveal some interesting patterns that might be of great importance for the future of our own species.

It has been known that leptin influences the hypothalamus in the brain but the exact way in which it communicates with the brain's pleasure center was not well understood. The researchers then injected leptin into the brains of the rats and they observed that as a result the efficiency of brain self-stimulation was greatly reduced. It is interesting that this effect lasted for as long as four days after leptin infusion. This indicates that leptin is involved in the long-term energy balance of the body and does not depend on short-term fluctuations of sugar levels in the blood.
