The theory of “Cytoelectric Coupling,” a novel concept suggesting that brain function is influenced by the brain’s electrical fields, has been proposed in a recent study. This groundbreaking research was conducted by a team from the Massachusetts Institute of Technology (MIT), City University of London, and Johns Hopkins University. The study expands on earlier research, demonstrating how the rhythmic electrical activity, also known as ‘brain waves,’ can adjust and regulate brain functions, leading to more flexible cognition.
According to the newly proposed “Cytoelectric Coupling” theory, these fluctuating electric fields play a critical role in improving the efficiency and robustness of the brain network. This is accomplished by influencing the physical structure of the brain’s molecular architecture.
The brain functions at various levels to perform diverse tasks, including thought processes. Information such as goals or visuals is represented through synchronized electrical activity within neuronal networks. At the same time, proteins and other biochemicals within and around each neuron physically carry out the mechanics required for their participation in these networks.
Researchers at MIT, City University of London, and Johns Hopkins University have presented a new paper that proposes the electrical fields within the network can influence the physical configuration of neurons’ sub-cellular components to optimize network stability and efficiency. This idea has been dubbed “Cytoelectric Coupling.”
Earl K. Miller, a professor at The Picower Institute for Learning and Memory at MIT, co-authored the paper. He says, “The information the brain is processing has a role in fine-tuning the network down to the molecular level.” His fellow authors, Dimitris Pinotsis of MIT and City University of London, and Gene Fridman of Johns Hopkins, also share this view.
In Miller’s lab, they focus on understanding how high-level cognitive functions such as working memory can rapidly and flexibly emerge from the activity of millions of individual neurons. They found that brain waves of different frequencies coordinate the specific neural circuits representing various thoughts.
The fast “gamma” rhythms help transmit visual images, while slower “beta” waves carry deeper thoughts. Miller’s lab also demonstrated that these wave bursts can carry predictions and enable writing in, holding onto, and reading out information in working memory. They have discovered a concept called “Spatial Computing,” suggesting that the brain may manipulate rhythms in specific physical locations to further organize neurons for flexible cognition.
The team’s recent work indicates that while the participation of individual neurons within networks can be variable and unreliable, the information carried by the networks is stably represented by the overall electric fields generated by their collective activity.
In the latest study, the team connects this model of rhythmic electrical activity with evidence that electrical fields can impact neurons at the molecular level. They mention previous studies about ephaptic coupling, where neurons affect each other’s electrical properties through the proximity of their membranes. They also cite research showing other electrical influences on cells and their components.
The authors suggest that the brain likely uses the capacity of electrical fields to configure neurons and other elements that form a network. This ability is vital for the network to function as intended. Miller compared it to how a successful television network doesn’t just transmit a clear signal, but also depends on how each viewer sets up their TV and living room furniture to optimize their viewing experience.
In their paper, the authors say that “Cytoelectric Coupling connects information at the meso- and macroscopic level down to the microscopic level of proteins that are the molecular basis of memory.” They invite anyone to test their hypothesis.
The research, which was published in the Progress in Neurobiology, was funded by the United Kingdom Research and Innovation (UKRI), the U.S. Office of Naval Research, The JPB Foundation, and The Picower Institute for Learning and Memory.
