What Do Single Neurons Know

But, the larger question remains as to how these individual dendrites and neuron outputs are used by the circuit and the brain as a whole. These findings are considerably different than sequences needing a group of neurons working in order and in a circuit. Even more unusual is the fact that (even young childrens’) brains are able to analyze and respond to information that is, in fact, so complex that the most advanced super computers cannot. Can individual cells do this as well?

Another new set of research shows that in a monkey brain, these responses of individual neurons are correlated somewhat with the final decision of the animal. This research used very limited visual information and showed that the final decisions of the animal using billions of neurons was perhaps relevant even to this small amount of information input given to individual cells.

It could be that the local neuron responded to the decision that was made by the larger circuits and brain. But, it doesn’t answer the question as to how the individual neuron relates to the brain.
