Words in the brain's language.

According to Pulvermüller (1999), words are represented in the brain by cell assemblies (Hebb, 1949) distributed over different areas, depending on semantic properties of the word. For example, a word with strong visual associations will be…

Difference between the brain's hemispheres in efficiency of intentional search of the mental lexicon with phonological, orthographic, and semantic strategies was investigated. Letter strings for lexical decision were presented at fixation, with a…

Brain regions active when our minds wander may hold a key to understanding neurological disorders and even consciousness itself

Eteenth century, Italian physiologist Angelo Mosso (18461910) became the first to experiment with the idea that changes in the flow of blood in the brain might provide a way of assessing brain function during mental activity. Mosso knew that the…

A Bayesian model of visual motion perception describes how the brain combines assumptions with evidence. A new study in this issue tests and expands the model, building connections between perception, the environment and neural responses.

Commentary on new findings concerning the role of dopamine. Data show that it is involved in reward, but that is may also play a role for any attention demanding stimulus. The best data suggests, however, that it signals expectancy of reward

Sometimes neurons get so excited that they fire in harmony. This synchronized firing has long excited neuroscientists, but they aren't sure what it means. Some have suggested that it allows the brain to perform sophisticated computations, such as…

Thirty years of brain imaging research has converged to define the brain's default network-a novel and only recently appreciated brain system that participates in internal modes of cognition. Here we synthesize past observations to provide strong…

In this paper, the basic words introduced by Swadesh(1952,1955) are used to uncover information about language evolution. In section 2, based on Chen (1996), Swadesh's 200-word list can be split into two sub-groups; the first 100 words, called high…
