A comparison is presented of the latencies of corticofugal effects from the contralateral somatosensory cortex (SI) onto the cat's dorsal column nuclei (d.c.n.) under pentobarbitone anaesthesia. The latencies for transmission in the ascending pathway from d.c.n. to SI after stimulation within the gracile and cuneate nuclei were found to be 3.3 ms for the(More)
Extracellular records were made from single identified lemniscal neurons of the cell-cluster regions of the cuneate and gracile nuclei, and of the lateral cervical nucleus, in pentobarbitone-anaesthetized cats. Forepaw, hind paw or face regions of the contralateral Sm I cortex were identified by recording through an inserted microelectrode which was then(More)
The numbers, laminar position, perikaryal and dendritic morphology, and axonal trajectories of postsynaptic cells ascending the dorsal column have been studied after implantation of HRP pellets in either the dorsal columns or dorsal column nuclei after destruction of the dorsolateral fascicle on one side. Observations made throughout the spinal cord gave(More)
Spinocervical cells were identified by retrograde labelling from implants of HRP in the dorsolateral fascicle after destruction of the dorsal columns. They lay in laminae III and IV throughout the cord in estimated numbers of 700, 450 and 1100 in lumbosacral enlargement, upper lumbar and thoracic cord, and brachial enlargement respectively. In the cord(More)
The distribution, dendritic trees and axonal courses of spinally projecting cells in the dorsal column nuclei were studied after labelling by retrograde HRP transport. The region of densest distribution was at the base of the two nuclei and in the area between them, extending for about 2 mm caudally from the obex. Only very few cells were found inside the(More)

Abstract A divide-and-conquer algorithm for exploiting policy function monotonicity is proposed and analyzed. To compute a discrete problem with n states and n choices, the algorithm requires(More)
In this paper, we study the interplay between the decision to default and capital accumulation. We …nd that conditional on a level of foreign indebtedness more capital reduces the likelihood of default and increases the price of debt. Large capital stocks have the additional bene…t of taming the severity of the contraction following default. Our(More)
Neurones have been identified and precisely located in the Sm 1 and S II cortex of the cat, which responded antidromically to stimulating the contralateral gracile or cuneate nucleus. They were much more numerous in Sm 1, with corticogracile cells medial and corticocuneate cells lateral, many lying buried in the roof of the cruciate or the coronal sulcus.(More)
Motivated by the recent experience of the U.S. and the Eurozone, we describe the quantitative properties of a New Keynesian model with a zero lower bound (ZLB) on nominal interest rates, explicitly accounting for the nonlinearities that the bound brings. Besides showing how such a model can be e¢ ciently computed, we …nd that the behavior of the economy is(More)
