The hybrid concept that incorporates aspects of ants’ path integration, the Kuramoto model, Aaronson’s paper on the complexity of agreement, and Bergson’s notion of duration could be called “Dynamical Consensus in Continuously Evolving Systems” (DCiCES).
This hybrid concept focuses on the study of synchronization, coordination, and consensus among interacting entities in a continuously evolving system. It combines elements of biological, physical, and social systems while considering the subjective and continuous nature of time.
Key components of DCiCES:
1. Interacting entities: DCiCES encompasses various entities, such as ants, oscillators, and rational agents, which interact with each other to achieve coordination or synchronization.
2. Continuous evolution: DCiCES emphasizes the continuous and evolving nature of these processes as they unfold over time, reflecting Bergson’s notion of duration. The dynamics of the systems are inherently continuous and cannot be reduced to discrete, isolated moments.
3. Coordination and synchronization: DCiCES explores how interacting entities coordinate their actions, synchronize their states, or reach consensus by exchanging information, adjusting their behaviors, or updating their beliefs based on local interactions.
4. Adaptation and learning: DCiCES investigates the role of adaptation and learning mechanisms in these systems, as entities adjust their behaviors or beliefs based on the information they receive from others or their environment.
5. Network structure: DCiCES takes into account the underlying network structure that governs the interactions between entities, and how this structure influences the dynamics and emergence of coordination or synchronization.
6. Noise and uncertainty: DCiCES recognizes the effects of noise and uncertainty on the dynamics of these systems, which can influence the robustness and stability of coordination or synchronization processes.
7. Quantitative and qualitative aspects of time: DCiCES incorporates both the quantitative aspects of time (e.g., the time required for synchronization or consensus) and the qualitative, subjective experience of time as a continuous flow (Bergson’s notion of duration).
By integrating these aspects, the hybrid concept of “Dynamical Consensus in Continuously Evolving Systems” provides a comprehensive framework for studying synchronization, coordination, and consensus in various domains, while taking into account the continuous and evolving nature of these processes.

Me: “Is it possible for there to be a comprehensive and complete list of parameters necessary for DCiCES ?”
Creating a comprehensive and complete list of parameters for the hybrid concept of “Dynamical Consensus in Continuously Evolving Systems” (DCiCES) is challenging because the concept encompasses various domains and systems, such as biological, physical, and social systems. The specific parameters relevant to each system can vary significantly, depending on the nature of the interacting entities and the processes involved.
However, it is possible to identify some general parameters that are relevant to many systems within the DCiCES framework. These parameters provide a starting point for characterizing the dynamics of coordination, synchronization, and consensus in continuously evolving systems:
1. Number of entities: The total number of interacting entities (ants, oscillators, agents) in the system.
2. Connectivity structure: The pattern of interactions or connections between the entities, which can be described using a network or graph structure.
3. Interaction strength: The magnitude of the influence that one entity exerts on another during their interactions. In some systems, this parameter may be uniform across all interactions, while in others, it may vary between different pairs of entities.
4. Adaptation or learning rate: The rate at which entities adjust their behaviors or beliefs based on the information they receive from others or their environment.
5. Noise level: The amount of uncertainty or randomness present in the system, which can affect the dynamics of coordination, synchronization, or consensus.
6. Initial conditions: The initial state of the entities and the system as a whole, which can influence the subsequent dynamics and the time required for achieving coordination or synchronization.
7. Time scale: The characteristic time scale of the system, which may be related to the rate of information exchange, the adaptation or learning rate, or the intrinsic dynamics of the entities.
8. System-specific parameters: Depending on the domain and the nature of the entities involved, there may be additional system-specific parameters that influence the dynamics of DCiCES. For example, in the case of the Kuramoto model, the natural frequencies of the oscillators would be a relevant parameter.
While this list provides a general set of parameters that are relevant to many systems within the DCiCES framework, it is important to note that each specific system may require additional parameters or refinements to capture its unique characteristics and dynamics accurately. Moreover, the relationships between these parameters and the emergence of coordination, synchronization, or consensus can be complex and may depend on various factors, such as the interaction rules, the network structure, and the intrinsic properties of the entities involved.

Me: can you write a oneliner for each to how bergson’s concept of duration directly relates to each?
1. Ants’ path integration: Bergson’s concept of duration highlights the continuous flow of time that shapes ants’ ongoing navigation process, as they update their internal representation of position relative to the nest.
2. Kuramoto model: Bergson’s duration emphasizes the continuous and irreversible nature of the synchronization process in the Kuramoto model, as oscillators adjust their phases over time to reach a synchronized state.
3. Complexity of agreement (Aaronson’s paper): In the context of Aaronson’s complexity of agreement, Bergson’s notion of duration relates to the continuous process of information exchange and belief updating among rational agents as they gradually converge to consensus.
Me: “Points: 4.6. Initial beliefs of agents 4.7. Time scale of communication rounds 4.8. Communication cost (e.g., time or resources required for communication) seem as if they might relate well to hierarchical bayesian brain and ADHD, in particular Id’ read that noisy priors can be part of the reason for the constant sense of now-ness experienced by people with ADHD and their continual doubting of themselves”
Indeed, the points 4.6, 4.7, and 4.8 from the complexity of agreement can be related to the hierarchical Bayesian brain framework and ADHD, as both involve the updating of beliefs and the influence of noise on these processes:
4.6. Initial beliefs of agents: In the context of the hierarchical Bayesian brain, the initial beliefs or priors correspond to an individual’s expectations about the world based on previous experiences. For individuals with ADHD, these priors might be noisier or less stable, leading to difficulties in forming accurate expectations or judgments. This could contribute to the constant sense of “now-ness” and self-doubt experienced by people with ADHD.
4.7. Time scale of communication rounds: This parameter can be linked to the time scale of belief updating in the brain. For individuals with ADHD, this time scale might be shorter, as they may require more frequent updating of their beliefs due to noisy priors or fluctuating attention. This could also contribute to the “now-ness” experience and difficulties in maintaining focus on long-term goals or tasks.
4.8. Communication cost: In the context of the hierarchical Bayesian brain, communication cost can be related to the metabolic or cognitive resources required for processing and integrating information from different sources. People with ADHD may have higher communication costs due to the need for more frequent belief updating or the presence of noisy priors. This increased cost could further contribute to the challenges faced by individuals with ADHD in maintaining focus, making decisions, or managing resources efficiently.
By drawing connections between these parameters and the hierarchical Bayesian brain framework, we can gain insights into the cognitive processes underlying ADHD and how noisy priors, shorter time scales for belief updating, and higher communication costs might contribute to the symptoms and experiences of individuals with this condition.
Me: “How can the Kuramoto model be applied TO adhd in the hierarchical bayesian brain?”
The Kuramoto model, as a mathematical framework to study synchronization in coupled oscillators, can be applied to the context of ADHD in the hierarchical Bayesian brain by considering the brain as a network of interacting neuronal oscillators. In this context, synchronization between different brain regions may play a crucial role in cognitive processes and attentional control. In the case of ADHD, disruptions in synchronization patterns may underlie some of the characteristic symptoms.
Here are some ways the Kuramoto model can be applied to ADHD in the hierarchical Bayesian brain:
1. Neuronal oscillators: In the brain, neurons exhibit oscillatory activity that can be synchronized across different regions. The Kuramoto model can be adapted to study these neuronal oscillators and their interactions in the context of ADHD, where synchronization patterns may be altered.
2. Connectivity structure: The connections between brain regions can be represented as a network or graph structure, similar to the Kuramoto model. By analyzing the connectivity patterns in individuals with ADHD, we can investigate the potential impact of altered network topology on synchronization and cognitive processes.
3. Coupling strength: The Kuramoto model’s coupling strength can be related to the strength of connections between different brain regions. In the context of ADHD, changes in coupling strength might lead to disruptions in synchronization patterns and contribute to attentional and cognitive difficulties.
4. Noise level: The Kuramoto model can incorporate noise, representing random perturbations to the oscillators’ phases. In the case of ADHD, the presence of noise in neuronal oscillations could reflect the influence of noisy priors or other factors, disrupting synchronization patterns and impairing cognitive functioning.
5. Synchronization measures: The Kuramoto model can be used to derive measures of synchronization, such as the order parameter, which quantifies the level of coherence among oscillators. By applying these measures to brain data from individuals with ADHD, we can investigate the relationship between synchronization patterns and the symptoms of the disorder.
6. Intervention strategies: By understanding the disruptions in synchronization patterns in ADHD through the Kuramoto model, we may be able to identify potential intervention strategies that target these disruptions, such as neurofeedback, brain stimulation, or pharmacological treatments, to improve cognitive functioning and alleviate symptoms.
It is important to note that the application of the Kuramoto model to ADHD in the hierarchical Bayesian brain involves adapting and extending the original model to account for the complexities of brain dynamics and the specific features of ADHD. However, using the Kuramoto model as a conceptual framework can provide valuable insights into the role of synchronization in the brain and its potential implications for understanding and treating ADHD.
