TL;DR: Low-dimensional representations of sensory signals are key to solving many of the computational problems encountered in high-level vision.
Abstract: Low-dimensional representations of sensory signals are key to solving many of the computational problems encountered in high-level vision. Principal component analysis (PCA) has been used in the pa...

TL;DR: It is shown that mouse T cells can be reliably primed in situ using dendritic cells as APC and a small but relevant vacuolar system for presenting antigens over a several day period in situ is suggested.
Abstract: T cells recognize peptides that are bound to MHC molecules on the surface of different types of antigen-presenting cells (APC). Antigen presentation most often is studied using T cells that have undergone priming in situ, or cell lines that have been chronically stimulated in vitro. The use of primed cells provides sufficient numbers of antigen-reactive lymphocytes for experimental study. A more complete understanding of immunogenicity, however, requires that one develop systems for studying the onset of a T cell response from unprimed lymphocytes, especially in situ. Here it is shown that mouse T cells can be reliably primed in situ using dendritic cells as APC. The dendritic cells were isolated from spleen, pulsed with protein antigens, and then administered to naive mice. Antigen-responsive T cells developed in the draining lymphoid tissue, and these T cells only recognized protein when presented on cells bearing the same MHC products as the original priming dendritic cells. In contrast, little or no priming was seen if antigen-pulsed spleen cells or peritoneal cells were injected. Since very small amounts of the foreign protein were visualized within endocytic vacuoles of antigen-pulsed dendritic cells, it is suggested that dendritic cells have a small but relevant vacuolar system for presenting antigens over a several day period in situ.

TL;DR: A simple encoder model, which is a reasonable idealization from known electrophysiological properties, yields a population in which the variation of the firing rate with time is a perfect replica of the shape of the input stimulus.
Abstract: A simple encoder model, which is a reasonable idealization from known electrophysiological properties, yields a population in which the variation of the firing rate with time is a perfect replica of the shape of the input stimulus. A population of noise-free encoders which depart even slightly from the simple model yield a very much degraded copy of the input stimulus. The presence of noise improves the performance of such a population. The firing rate of a population of neurons is related to the firing rate of a single member in a subtle way.

TL;DR: It is shown that leptin also acts acutely to increase glucose metabolism, although studies of leptin's effect on glucose metabolism have typically been confounded by the weight-reducing actions of leptin treatment, which by itself could affect glucose homoeostasis.
Abstract: Leptin is an adipocyte hormone that functions as an afferent signal in a negative feedback loop regulating body weight, and acts by interacting with a receptor in the hypothalamus and other tissues. Leptin treatment has potent effects on lipid metabolism, and leads to a large, specific reduction of adipose tissue mass after several days. Here we show that leptin also acts acutely to increase glucose metabolism, although studies of leptin's effect on glucose metabolism have typically been confounded by the weight-reducing actions of leptin treatment, which by itself could affect glucose homoeostasis. We have demonstrated acute in vivo effects of intravenous and intracerebroventricular administrations of leptin on glucose metabolism. A five-hour intravenous infusion of leptin into wild-type mice increased glucose turnover and glucose uptake, but decreased hepatic glycogen content. The plasma levels of insulin and glucose did not change. Similar effects were observed after both intravenous and intracerebroventricular infusion of leptin, suggesting that effects of leptin on glucose metabolism are mediated by the central nervous system (CNS). These data indicate that leptin induces a complex metabolic response with effects on glucose as well as lipid metabolism. This response is unique to leptin, which suggests that new efferent signals emanate from the CNS after leptin treatment.
