Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - How does the brain code and process incoming information, how does it recog nize a certain object, how does a certain Gestalt come into our awareness One of the key issues to conscious realization of an object, of a Gestalt is the attention de voted to the corresponding sensory input which evokes the neural pattern underly ing the Gestalt. This requires that the attention be devoted to one set of objects at a time. However, the attention may be switched quickly between different objects or ongoing input processes. It is to be expected that such mechanisms are reflected in the neural dynamics: Neurons or neuronal assemblies which pertain to one object may fire, possibly in rapid bursts at a time. Such firing bursts may enhance the synaptic strength in the corresponding cell assembly and thereby form the substrate of short-term memory. However, we may well become aware of two different objects at a time. How can we avoid that the firing patterns which may relate to say a certain type of move ment (columns in V5) or to a color (V 4) of one object do not become mixed with those of another object Such a blend may only happen if the presentation times be come very short (below 20-30 ms). One possibility is that neurons pertaining to one cell assembly fire syn chronously. Then different cell assemblies firing at different rates may code different information.

Original Wraps. Zustand: Very Good+. First Edition. First Edition. Original Wraps. With posthumously designed book plate by a friend of Oliver's, incorporating his longstanding love of cephalopods. From the library of Dr. Oliver Sacks, the renowned neurologist, author, and educator. He was, in his life, celebrated for his contributions to the understanding of the human brain and his ability to communicate complex scientific concepts to a broader audience. In doing so, he highlighted the profound impact of neurological disorders on human identity and experience. His library is a reflection of this remarkable polymath's questing mind. Light shelfwear, else tight, bright, and unmarred. 8vo. xi, 569pp. + index, illus (b/w), charts. Original color glossy wrappers.
