Intelligence is based on neuronal efficiency

The brain achieves a high level of thinking while minimizing neuronal activity

New research has determined that intelligence is based on an efficient neuronal organization that allows obtaining the best result with minimal neuronal activity. The smarter a person is, the less active dendrites are in their cerebral cortex.

Since the mid-nineteenth century, scientists have been trying to discover the neuropsychological and neurobiological aspects of human intelligence. Until now it had been established that intelligent people have a higher brain volume.

The most recent research that had also reached this conclusion was published a few days ago, as we reported in another article. For the authors of this research, cognitive ability and intelligence are related to the size of the cerebral cortex, which is thicker in taller and smarter people.

Other previous research found in turn that smarter people have an extended neural architecture that allows them to process information faster and have a greater capacity to store memories.

New research has determined, however, that smart people actually have a less dense neural network, but are organized in a more effective way.

In the case of this investigation, the notion of intelligence and its…
