It is an interesting and noticeable fact that in the early stages of language production, children omit certain elements from their speech. Upon closer inspection, it becomes clear that children regularly omit certain function morphemes, as opposed to content words. Function morphemes (including determiners, pronouns, auxiliary verbs, and inflection morphemes) form a natural class from both a p...

According to the "modular" hypothesis, reading is a serial feedforward process, with part of left ventral occipitotemporal cortex the earliest component tuned to familiar orthographic stimuli. Beyond this region, the model predicts no response to arrays of false font in reading-related neural pathways. An alternative "connectionist" hypothesis proposes that reading depends on interactions betwe...

We compare the volumes of projections of convex bodies and the volumes of the projections of their sections, and, dually, those of sections of convex bodies and of sections of their circumscribed cylinders. For L ⊂ R a convex body, we take n random segments in L and consider their ‘Minkowski average’ D. For fixed n, the pth moments of V (D) (1 ≤ p < ∞) are minimized, for V (L) fixed, by the ell...

UNLABELLED The brain commonly exhibits spontaneous (i.e., in the absence of a task) fluctuations in neural activity that are correlated across brain regions. It has been established that the spatial structure, or topography, of these intrinsic correlations is in part determined by the fixed anatomical connectivity between regions. However, it remains unclear which factors dynamically sculpt thi...

Research based on functional imaging and neuronal recordings in the barrel cortex subdivision of primary somatosensory cortex (SI) of the adult rat has revealed novel aspects of structure-function relationships in this cortex. Specifically, it has demonstrated that single whisker stimulation evokes subthreshold neuronal activity that spreads symmetrically within gray matter from the appropriate...

Introduction Cortico-striato-thalamo-cortical interconnections are thought to be organized in anatomically and functionally segregated loops. The tripartite model proposes their division into pure motor, associative and limbic portions. In analogy, anatomical studies revealed subdivision of the involved brain structures: in cortex and striatum pure motor areas are located posterior to associati...
