Recent work on the syntax and semantics of functional projections within the noun phrase has had as one goal an explanation for the crosslinguistic distribution of “bare” (determinerless) noun phrases. This article provides an account for an apparent anomaly: the relatively free occurrence of bare noun phrases under coordination. We argue that this construction involves coordination of projecti...

The projections of mechanosensory hairs located on the dorsal and lateral head of the adult haematophagous bug Triatoma infestans were analyzed by means of cobalt filling. Axons run into the anterior and posterior tegumentary nerve and project through the brain to the ventral nerve cord. The fibres are small in diameter and run as a fascicle. Some branches run into suboesophageal and prothoraci...

Introduction: Reflecting the intricacy of the connectivity in the brain, 3D brain tractography models are generally visually dense. Therefore, it is often difficult to ascertain tract projections as well as anatomical and functional structures clearly. In this context, we introduce a connectivity (“dependency”) map of tract projections in a framework that uses two-dimensional map representation...

The possibility of considering random projections to identify probability distributions belonging to parametric families is explored. The results are based on considerations involving invariance properties of the family of distributions as well as on the random way of choosing the projections. In particular, it is shown that if a one-dimensional (suitably) randomly chosen projection is Gaussian...

We have used a GAL4 enhancer-trap line driving the expression of a lacZ construct to examine the reorganisation of an identified group of proprioceptive sensory neurons during metamorphosis in Drosophila. The results show that whilst most larval sensory neurons degenerate during the first 24 hours of metamorphosis a segmentally repeated array of 6 neurons per segment persists into the adult sta...

The locus coeruleus (LC) projects throughout the brain and spinal cord and is the major source of central noradrenaline. It remains unclear whether the LC acts functionally as a single global effector or as discrete modules. Specifically, while spinal-projections from LC neurons can exert analgesic actions, it is not known whether they can act independently of ascending LC projections. Using vi...

0. Introduction The status of functional categories in early child language has been a subject of debate for much of the last decade (Hyams 1986, Radford 1990, Platzack 1992, Rizzi 1993, Wexler 1994). In general, proponents of the ‘No Functional Categories’ position claim that production data from early child language clearly demonstrates that the differences between child language and adult la...

The effects of signals transmitted from the brain to the spinal locomotor networks by a population of command neurons are determined by specific functional projections of each individual neuron. To reveal these projections, we used a simple vertebrate model, the lamprey, in which responses of the spinal networks to spikes in single reticulospinal axons were detected by using the spike-triggered...

In our previous work, we introduced a convex-concave regularization approach to the reconstruction of binary objects from few projections within a limited range of angles. A convex reconstruction functional, comprising the projections equations and a smoothness prior, was complemented with a concave penalty term enforcing binary solutions. In the present work we investigate alternatives to the ...
