This chapter focuses on dynamic coordination and how it is achieved, how it is related to cognitive functions and learning processes, and the role of neural oscillations in different frequency bands for dynamic coordination. It also considers modulation of coordination at the systems level and the relation of the mechanisms underlying coordination of behavior and cognition to neuropsychiatric disorders. In addition, the chapter examines dynamic coordination that arises from self-organization, the reduction in dimensionality associated with dynamic coordination, the theory of Coherent Infomax, Dynamic Pattern Theory, how optimization and synchrony are related to dynamic coordination, neural synchrony during human ontogeny, and how coordination contributes to perceptual and motor development. The chapter concludes with a discussion of the role of different frequency bands in sensory processing, attention and awareness, and motor circuits, together with how the prefrontal cortex modulates dynamic coordination.Less

Episodic memory is essential for our day-to-day functions, enabling us to remember where we parked the car, at what time we walked the dog, or what a friend said days ago. This book draws on the developments in neuroscience to present a quantitative model describing the brain mechanisms for encoding and remembering such episodes as “spatiotemporal trajectories.” It reviews physiological breakthroughs on the regions of the brain involved in episodic memory, including the discovery of grid cells, the cellular mechanisms of persistent spiking and resonant frequency, and the topographic coding of space and time. These discoveries inspire a theory for understanding the encoding and retrieval of episodic memory not just as discrete snapshots but as a dynamic replay of spatiotemporal trajectories, allowing us to “retrace our steps” to recover a memory. On the behavioral level, the author emphasizes the capacity to encode and retrieve spatiotemporal trajectories from personal experience, including the time and location of individual events. On the biological level, he focuses on the dynamical properties of neurons and networks in the brain regions mediating episodic memory, addressing the role of neural oscillations and the effect of drugs on episodic memory. In the main text of the book, the author presents the model in narrative form, accessible to scholars and advanced undergraduates in many fields. In the appendix, he presents the material in a more quantitative style, providing mathematical descriptions appropriate for advanced undergraduates and graduate students in neuroscience or engineering.Less

The study of identifiable neurons, a common feature of invertebrate nervous systems, has made it possible to construct a detailed cell-to-cell connectivity map using electrophysiological methods that can inspire the design of biomimetic systems. This chapter describes how the analysis of the neural circuitry in the lobster stomatogastric ganglion (STG) has provided some general principles underlying oscillatory and rhythmic behavior in all animals. The rhythmic and oscillatory patterns produced by the two STG central pattern generating (CPG) circuits are a result of two cooperative mechanisms, intrinsically bursting pacemaker neurons and synaptic network properties. Also covered are the major neuromodulatory and neural control mechanisms. The chapter discusses how a deep knowledge of the stomatogastric circuitry has led to the development of electronic neurons for biomimetic devices that can be used for experimental and prosthetic applications The chapter concludes with a section on new techniques that may help with unraveling oscillatory circuits in the brain.Less
