Neurolinguistic accounts of sentence comprehension identify a network of relevant brain regions, but do not detail the information flowing through them. We investigate syntactic information. Does brain activity implicate a computation over hierarchical grammars or does it simply reflect linear order, as in a Markov chain? To address this question, we quantify the cognitive states implied by alt...

Schizophrenia is a psychiatric illness in which disorders of thought content are a prominent feature. The disruption of normal flow of thought, or "Formal Thought Disorder" (FTD), has been traditionally assessed through the content and form of patients' speech, and speech abnormalities in schizophrenia were considered as a by-product of the disruption in conceptual structures and associative pr...

FROM ITS INCEPTION general semantics has had a close affinity with neurology and psychology . This is shown by the adoption by general semanticists of of such terms as 'neuro-semantic mechanisms,' 'neuro-symbolic processes,' 'neurolinguistic environment,' 'neuro-evaluational factors,' and in frequent announcements to the effect that general semantics ' . . . is concerned with the linguistic and...

This paper presents evidence for a new model of the functional anatomy of speech/language (Hickok & Poeppel, 2000) which has, at its core, three central claims: (1) Neural systems supporting the perception of sublexical aspects of speech are essentially bilaterally organized in posterior superior temporal lobe regions; (2) neural systems supporting the production of phonemic aspects of speech c...

In this paper, a new recurrent neural network is proposed for solving convex quadratic programming (QP) problems. Compared with existing neural networks, the proposed one features global convergence property under weak conditions, low structural complexity, and no calculation of matrix inverse. It serves as a competitive alternative in the neural network family for solving linear or quadratic p...

Neurolinguistic investigations into the processing of structured sentences as well as simple adjective-noun phrases point to the left anterior temporal lobe (LATL) as a leading candidate for basic linguistic composition. Here, we characterized the combinatory profile of the LATL over a variety of syntactic and semantic environments, and across two languages, English and Arabic. The contribution...

Computational Linguistics and Natural Language have long been targets for Machine Learning, and a variety of learning paradigms and techniques have been employed with varying degrees of success. In this paper, we review approaches which have adopted an unsupervised learning paradigm, explore the assumptions which underlie the techniques used and develop an approach to empirical evaluation. We c...

The study of language in the brain is the study of the computations responsible for the structure and processing of language. Hemodynamic imaging techniques can make a contribution to this area, but only if paired with a theory of the underlying formal processes. Statements like 'syntax is mediated by Broca's area' are too coarse (cognitively and cytoarchitectonically) to constitute insights in...
