 Two preliminary considerations should be kept in mind. First, a distinction must be drawn between the neural realization of word forms, i.e., traces of acoustic, articulatory, graphic, and motor configurations (‘peripheral lexicons’), and the neural correlates of lexical meanings (‘concepts’). A patient can understand what is the object represented by a picture shown to her (and give evidence of her understanding, e.g., by miming the object’s function) while being unable to retrieve the relevant phonological form from her output lexicon (Warrington 1985; Shallice 1988). Second, there appears to be wide consensus about the irrelevance to brain processing of any distinction between strictly semantic and factual or encyclopedic information (e.g., Tulving 1972; Sartori et al. 1994). Whatever information is relevant to such processes as object recognition or confrontation naming is standardly characterized as ‘semantic’. This may be taken as a stipulation—it is just how neuroscientists use the word ‘semantic’—or as deriving from lack of evidence for any segregation between the domains of semantic and encyclopedic information (see Binder et al. 2009). Be that as it may, in present-day neuroscience there seems to be no room for a correlate of the analytic/synthetic distinction. Moreover, in the literature ‘semantic’ and ‘conceptual’ are often used synonymously; hence, no distinction is drawn between lexical semantic and conceptual knowledge. Finally, the focus of neuroscientific research on “semantics” is on information structures roughly corresponding to word-level meanings, not to sentence-level meanings: hence, so far neuroscientific research has had little to say about the compositional mechanisms that have been the focus (and, often, the entire content) of theories of meaning as pursued within formal semantics and philosophy of language.
