Cognitive dynamics brain

With these tools in hand, further definition of a cognitive dynamics analysis and its insights into the normative flow of information will provide a window into the cognitive dynamics of ASD. The plausible conclusion that autistic behaviors can emerge from non-autistic brains will be briefly explored.

The dynamic interaction of perception, emotion, and cognition in the creation of conscious experience is highlighted by the visual image transformations that are enhanced by natural and drug-induced alterations of brain-mind state. Later in the book we will read the detailed accounts of such transformations in the reports by careful self-observers such as Albert Hofmann (who discovered the psychotogcnic potential of LSD) and Heinrich Kliiver (who used mescaline to study visual hallucination). In Hofmann and Kliiver s work, the most valuable descriptions are formal. That is, they emphasize form rather than content.

Temporal patterns and oscillations have been observed in a very broad spectrum across various spatial scales. For example, periodic dynamics have been studied in gene expression patterns in the cell division cycle and the cellular redox state alterations, while the genome-wide oscillations at the transcript and protein levels indicate the cell cycle as a developmental process [33]. Spatiotemporal oscillations have been observed in mitochondria, transmembrane potentials, heart excitation waves, neural activities and brain dynamics, cognition and verbal working memory, and even bacteria [16, 34-37]. 

Woolf s account of the unconscious optics of film, and of film s future, is based on a clear and repeated premise that film is a new dynamic, psychic and cognitive process. When the eye and the brain together, Woolf suggests,... 

Synchronization is one snch interesting collective dynamical phenomenon, which plays a crucial role in the large-scale properties of dynamical systans. In particular, in the brain, synchronization among the nenrons acts as a backbone for occurrence of various functional and cognitive events. In this section, we have summarized some of the interesting physiological phenomena where synchronization plays a crucial role (1) ERD, (2) the existence of chimera and GCC states, and (3) the occurrence of mass synchronization and its control. 

In order to model the brain and its complex abilities, it is quite adequate to distinguish the following categories. In neuronal-level models, studies are concentrated on the dynamic and adaptive properties of each nerve cell or neuron, in order to describe the neuron as a unit. In network-level models, identical neurons are interconnected to exhibit emergent system functions. In nervous-system-level models, several networks are combined to demonstrate more complex functions of sensory perception, motor functions, stability control, etc. In mental-operation-level models, the basic processes of cognition, thinking, problem-solving, etc. are described.
