Connection cognition

Each sensory afferent neuron connects with an interneuron or accessory neuron. These interneurons are located entirely within the CNS, with the majority occurring in the cerebral cortex. They form numerous interconnections and are the means by which all cognitive information, thoughts and feelings, are processed. It should be emphasised that the main role of this processing of information is inhibitory. The sensory receptors provide the CNS with a massive amount of data. The interneurons process and filter this into a limited amount of useful and important informa tion. Conscious information processing forms just one part of this activity. A great deal of brain activity is concerned with routine processes, which continue without conscious awareness. [Pg.10]

Studies that have focused on neuritic response to the NP rather than to presence of the plaque core itself have been more successful in finding a relationship between plaque-associated dystrophic neurites and dementia [30]. These studies suggest that plaque cores per se may only be an initiating event and that the gradual effects of the plaque core on adjacent neuronal pathway architecture may actuate the ultimate disruption of function. The timeframe over which the latter occurs, and the nature of how plaque-induced changes in synaptic connectivity ultimately affect cognition, is not known. [Pg.322]

Mechanistically speaking,SRR-mediated off-line strengthening of synaptic connections requires only pair-wise reactivation between two activated neurons. Thus, this synaptic reactivation feature is different from the reactivation of memory at the cognitive level. Although the SRR... [Pg.869]

The pons and cerebellum (metencephalon) form the middle portion of the brain stem, bordered rostrally by the midbrain and caudally by the medulla. It also contains a portion of the brain stem and several nuclei important to arousal and sleep. The cerebellum branches off of the back of the brain stem. It has a cortical surface and deep nuclei imbedded in white matter. Through its connections, it has involvement in diverse functions including balance, fine motor coordination, and even cognition. [Pg.62]

To some extent, these ideas about consciousness are present in modern cognitive science, although with different forms and terminology, and the interested reader can refer to more specialized literature, for example the work by Damasio (1999) or by le Doux (2002). There are now many books on the subject of consciousness and many novel academic institutions devoted to the study of consciousness, with much emphasis on the relation between brain and mind. This is certainly remarkable in an area dominated by the molecular paradigm. Very little has yet been done to connect this with a bio-logical theory of life as a property from within, but I believe that the trend will move in this direction. In this sense, Francisco Varela has again been somewhat of a pioneer. [Pg.175]

All of this is, of course, standard practice in cognitive behavioral therapy, and I do not pretend that it is in itself innovative. My only contribution is to show how comfortably it sits on the solid foundation of the mind-brain paradigm. At the same time, it calls forth from that paradigm a mechanistic model of change at the level of the brain, namely a shift in balance and in specific connections between the executive functions of the dorsolateral prefrontal cortex and the limbic system. [Pg.312]

This technique allows the simultaneous treatment of about m — 3 to about m — 10 features for the visual assessment of similarities or dissimilarities of n objects. The m features are arranged as vectors with one starting point in a star. Values of the features (star axis) can be connected and a star is formed. Each object is represented as one star. Similarities between the objects are easily seen and human imagination is only necessary for pattern cognition. [Pg.147]

The prefrontal cortex (PFC) is the anterior part of the frontal lobes of the brain. It lies in front of the motor and premotor areas. The PFC is divided into the lateral, orbitofrontal, and medial prefrontal areas (Barbas and Pandya, 1987, 1989). Comprehensive reviews of this structure and functions of the PFC have been published in various forms (Fuster, 1997 Goldman-Rakic, 1987 Miller and Cohen, 2001 Passingham, 1993 Tanji and Hoshi, 2008). The PFC possesses a wealth of anatomical connectivity with multiple cortical and subcortical areas, and is involved in broad aspects of behavioral control. The PFC has been implicated in complex cognitive behaviors, social behaviors, and personality expression. Recent studies of this area have revealed its role in the control of a much broader spectrum of functions, such as cross-modal and cross-temporal association of information, in the executive control of behavior, and in the top-down control of neural networks involving the cortical and subcortical areas. Among them, the executive control of action was a term coined to capture various aspects of PFC function. [Pg.6]
