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- | | 出版日期 | Book 1994 | | 關(guān)鍵詞 | attention; brain; cortex; electroencephalography (EEG); information processing; memory; neurons | | 版次 | 1 | | doi | https://doi.org/10.1007/978-1-4899-1307-4 | | isbn_softcover | 978-1-4899-1309-8 | | isbn_ebook | 978-1-4899-1307-4 | | copyright | Springer Science+Business Media New York 1994 |
