Universal theory of brain waves: from linear loops to nonlinear synchronized spiking and collective brain rhythms (supplemental material: brain wave loops movies)
<p>This is a collection of videos supplementing the paper "Universal theory of brain waves: from linear loops to nonlinear synchronized spiking and collective brain rhythms"</p> <p>Examples of wave trajectories and emergent persistent loop patterns for the spherical shell cortex model with<br> varying amounts of tensor anisotropy and inhomogeneous shell layer thickness.</p> <p><br> Examples of brain wave trajectories and emergent persistent loop patterns for cortical fold geometry with different<br> approaches used for estimation of inhomogeneity and anisotropy. Among those examples are several simple cases with variable inhomogeneity and fixed anisotropy (similar to the above spherical shell cortex model) as well as with more complex estimates of anisotropy based on multiple diffusion gradients MRI (dMRI) acquisitions.</p>
Introduction to and application of synchronization theory
<p><strong>Abstract of the lecture</strong></p> <p>In nature, oscillations are one of the main forms of motion and these oscillating systems are not isolated. So, they interact, communicate in different kinds of complex ways. With this, synchronization is the most fundamental phenomenon exhibited by these systems. In the first part this talk, the basics of synchronization theory will be discussed. Applications of synchronization theory will be demonstrated in different engineering and natural systems, in the second part of my lecture. The engineering systems include thermoacoustic system, aeroelastic system, and natural circulation loop. Through these applications, we will discuss how synchronization theory helps not only describing different transitional phenomena but also indicating the possible control measures.</p> <p><strong>References:</strong></p> <ol> <li>Mondal, S., Unni, V.

Data from: A quantitative theory of gamma synchronization in macaque V1
Gamma-band synchronization coordinates brief periods of excitability in oscillating neuronal populations to optimize information transmission during sensation and cognition. Commonly, a stable, shared frequency over time is considered a condition for functional neural synchronization. Here, we demonstrate the opposite: instantaneous frequency modulations are critical to regulate phase relations and synchronization. In monkey visual area V1, nearby local populations driven by different visual stimulation showed different gamma frequencies. When similar enough, these frequencies continually attracted and repulsed each other, which enabled preferred phase relations to be maintained in periods of minimized frequency difference. Crucially, the precise dynamics of frequencies and phases across a wide range of stimulus conditions was predicted from a physics theory that describes how weakly coupled oscillators influence each other's phase relations. Hence, the fundamental mathematical principle of synchronization through instantaneous frequency modulations applies to gamma in V1, and is likely generalizable to other brain regions and rhythms.
