For most native English speakers, the meanings of words like “blue,” “cup,” “stumble,” and “carve” seem quite natural. Research in semantic typology has shown, however, that they are far from universal. Although the roughly 6,500 languages around the world have many similarities in the sorts of concepts they encode, they also vary greatly in how they partition particular conceptual domains, how they map those domains onto syntactic categories, which distinctions they force speakers to habitually track, and how deeply they weave certain notions into the fabric of their grammar. Although these insights from semantic typology have had a major impact on psycholinguistics, they have mostly been neglected by the branch of cognitive neuroscience that studies how concepts are represented, organized, and processed in the brain. In this book, David Kemmerer exposes this oversight and demonstrates its significance. He argues that as research on the neural substrates of semantic knowledge moves forward, it should expand its purview to embrace the broad spectrum of cross-linguistic variation in the lexical and grammatical representation of meaning. Otherwise, it will never be able to achieve a truly comprehensive, pan-human account of the cortical underpinnings of concepts. The book begins by elaborating the different perspectives on concepts that currently exist in semantic typology and cognitive neuroscience. Then it shows how a synthesis of these approaches can lead to a more unified understanding of several domains of meaning—specifically, objects, actions, and spatial relations. Finally, it explores multiple issues involving the interplay between language, cognition, and consciousness.

The Birimian of West African Craton (WAC) is known for its gold potential. Among Birimian structures, N-S and NE-SW trends have been defined as controlling gold mineralizations in Kedougou-Kenieba Inlier (KKI), whereas some of these structures are not gold-bearing. To determine structures related to gold mineralization, airborne electromagnetic data collected during the “Système Minier” of Mali have been processed and interpreted. Identified lineaments have been followed in the ground to establish their link with gold showings in the Kenieba area. Geophysical interpretations show trends similarity for different orders of conductivity. They allowed for characterizing resistance and conductive structures with prevalent N-S and NE-SW directionalities. Conductive structures are qualified as good conductors and are strongly related to known Artisanal Mining Sites (AMS). They coincide with tourmaline sandstones and quartz-albite veins, which are both often artisanally recognized as indicators of gold mineralization in Western Mali. Field observations show that resistance structures correspond to felsic rocks. These structures can bear gold only when silicified and they have spatial relations with Artisanal Mining Sites (AMS) within the Kenieba area. This study shows the efficiency of electromagnetic methods to characterize Birimian structures in relation to the gold mineralization in Kedougou-Kenieba Inlier (KKI).

Any explanation of vestibular micromechanics must include the roles of the otolithic and cupular membranes. However, micromechanical models of vestibular function have been hampered by unresolved questions about the microarchitectures of these membranes and their connections to stereocilia and supporting cells. Otolithic membranes are notoriously difficult to preserve because of severe shrinkage and loss of soluble components. We have empirically developed fixation procedures that reduce shrinkage artifacts and more accurately depict the spatial relations between the otolithic membranes and the ciliary bundles and supporting cells.We used White Leghorn chicks, ranging in age from newly hatched to one week. The inner ears were fixed for 3-24 h in 1.5-1.75% glutaraldehyde in 150 mM KCl, buffered with potassium phosphate, pH 7.3; when postfixed, it was for 30 min in 1% OsO4 alone or mixed with 1% K4Fe(CN)6. The otolithic organs (saccule, utricle, lagenar macula) were embedded in Araldite 502. Semithin sections (1 μ) were stained with toluidine blue.
