An AI Within a Single Cell: Human Neurons Shown to Handle Complex Computations
Publication date: August 13, 4:30 p.m.
A recent study by researchers from the Hebrew University of Jerusalem and VU Amsterdam has revealed that individual neurons in the human cerebral cortex can perform more sophisticated computations than previously thought. The findings, reported by ScienceDaily, came out of a comparison of human neurons with those of other mammals using computer modeling and artificial intelligence. This line of research sits at the intersection of neuroscience and machine learning.
The human brain contains roughly 100 billion nerve cells. The team developed a way to measure the computational complexity of individual neurons, linking their physical structure to their ability to process information. Using simulations and AI, they found that a single human neuron can handle more information than a simple on/off switch.
Why Neurons Are So Powerful
Remarkably, one neuron can carry out operations reminiscent of a deep artificial neural network, such as helping to distinguish images. Human cortical neurons have branched dendrites and distinctive electrical characteristics that make them exceptionally complex computing devices. As Professor Idan Segev noted,
“a single human neuron can be viewed as a complex computing device, not a simple switch.”
These results could have a major impact on the field of artificial intelligence. They indicate that human neurons process information at a level similar to modern AI, which may help scientists better understand how the brain works and inspire improved machine-learning algorithms.
The study highlights the importance of looking at neurons from both medical and technological angles: their computational abilities may open new possibilities for AI development. Clarifying the role that neurons play in complex calculations could also generate new approaches in neuroscience and lead to more efficient algorithms that mimic the human brain.
Understanding the computational power of human neurons could shed light on how the brain organizes information. This is particularly relevant in the context of recent discoveries about the brain's mechanisms in forming a cohesive perception of the world.
