Spatially Masked Regression Reveals Local and Distributed Predictability in Electrophysiological Recordings
Maryam Ostadsharif Memar, Nima Dehghani
Neural recordings are often interpreted as local measurements, yet the signal at any one sensor can also reflect structured activity distributed across the broader network. This ra…
Symmetry's Edge in Cortical Dynamics: Multiscale Dynamics of Ensemble Excitation and Inhibition
Nima Dehghani
Creating a quantitative theory for the cortex presents challenges and raises questions. What are the significant scales--micro, meso, or macroscopic? What are the interactions--pai…
Systematizing Cellular Complexity: A Hilbertian Approach To Biological Problems
Nima Dehghani
Examining individual components of cellular systems has been successful in uncovering molecular reactions and interactions. However, the challenge lies in integrating these compone…
Physical Computing: A Category Theoretic Perspective on Physical Computation and System Compositionality
Nima Dehghani, Gianluca Caterina
This paper introduces a category theory-based framework to redefine physical computing in light of advancements in quantum computing and non-standard computing systems. By integrat…
Ensemble Inhibition and Excitation in the Human Cortex: an Ising Model Analysis with Uncertainties
Cristian Zanoci, Nima Dehghani, Max Tegmark
The pairwise maximum entropy model, also known as the Ising model, has been widely used to analyze the collective activity of neurons. However, controversy persists in the literatu…
A computational perspective of the role of Thalamus in cognition
Nima Dehghani, Ralf D. Wimmer
Thalamus has traditionally been considered as only a relay source of cortical inputs, with hierarchically organized cortical circuits serially transforming thalamic signals to cogn…
Causal Unit of Rotors in a Cardiac System
Hiroshi Ashikaga, Francisco Prieto-Castrillo, Mari Kawakatsu +1
The heart exhibits complex systems behaviors during atrial fibrillation (AF), where the macroscopic collective behavior of the heart causes the microscopic behavior. However, the r…
Design of the Artificial: lessons from the biological roots of general intelligence
Nima Dehghani
Our fascination with intelligent machines goes back to ancient times with the mythical automaton Talos, Aristotle's mode of mechanical thought (syllogism) and Heron of Alexandria's…
Dynamic Balance of Excitation and Inhibition in Human and Monkey Neocortex
Nima Dehghani, Adrien Peyrache, Bartosz Telenczuk +5
Balance of excitation and inhibition is a fundamental feature of in vivo network activity and is important for its computations. However, its presence in the neocortex of higher ma…
Avalanche analysis from multi-electrode ensemble recordings in cat, monkey and human cerebral cortex during wakefulness and sleep
Nima Dehghani, Nicholas G. Hatsopoulos, Zach D. Haga +5
Self-organized critical states are found in many natural systems, from earthquakes to forest fires, they have also been observed in neural systems, particularly, in neuronal cultur…
Comparative power spectral analysis of simultaneous elecroencephalographic and magnetoencephalographic recordings in humans suggests non-resistive extracellular media
Nima Dehghani, Claude Bedard, Sydney S. Cash +2
The resistive or non-resistive nature of the extracellular space in the brain is still debated, and is an important issue for correctly modeling extracellular potentials. Here, we…
