Cortical Organization of Bilingualism
Language is a uniquely human phenomenon. People are able to communicate infinite ideas to one another through the use of words. Across the world people communicate in numerous different languages. Although people readily attain proficiency at any language they are exposed to as a child, the difficulties of learning a language later in life, past the critical period, are well known. While the co...
متن کاملCortical organization of language.
Recent data obtained by various methods of clinical investigations suggest an organization of language in the human brain involving compartmentalization into separate systems subserving different language functions. Each system includes multiple essential areas localized in the frontal and temporoparietal cortex of the dominant hemisphere, as well as widely dispersed neurons. All components of ...
متن کاملNoise, neural codes and cortical organization.
Cortical circuitry must facilitate information transfer in accordance with a neural code. In this article we examine two candidate neural codes: information is represented in the spike rate of neurons, or information is represented in the precise timing of individual spikes. These codes can be distinguished by examining the physiological basis of the highly irregular interspike intervals typica...
متن کاملCortical organization of environmental sounds by attribute.
Semantic knowledge is supported by a widely distributed neuronal network, with differential patterns of activation depending upon experimental stimulus or task demands. Despite a wide body of knowledge on semantic object processing from the visual modality, the response of this semantic network to environmental sounds remains relatively unknown. Here, we used fMRI to investigate how access to d...
متن کاملA testable model of global cortical organization.
This report advances a testable model of cortical organization which is tied to gamma band (20-150 Hz) neuroelectric oscillations. The elements of the model function as pattern recognizers and are assumed to be composed of a few cm2 of cortical tissue. Presumed modes of instability in the activity of this network of large units are proposed as the underlying neurophysiological basis of a variet...
