Abstract:
The hypothalamus is the focus of many peripheral signals and neural pathways that control energy homeostasis and body weight. Emphasis has moved away from anatomical concepts of ‘feeding’ and ‘satiety’ centres to the specific neurotransmitters that modulate feeding behaviour and energy expenditure. We have chosen three examples to illustrate the physiological roles of hypothalamic neurotransmitters and their potential as targets for the development of new drugs to treat obesity and other nutritional disorders. Neuropeptide Y (NPY) is expressed by neurones of the hypothalamic arcuate nucleus (A

Abstract. Neuropeptide Y (NPY) is a 36 amino acid peptide, widely distributed throughout the brain and is found in hypothalamic neurones. This latter finding suggests that NPY may possess a hypophysiotropic function. A number of studies have demonstrated effects of NPY on LH and GH secretion by rat pituitary cells. We report here the results of experiments investigating the effects of NPY on GH secretion by tumorous human somatotropic pituitary cells in culture. NPY (0.25–25 nmol/l) inhibited GH secretion by 20–53%, the maximal effect depending upon the tumour studied. The potency of NPY was l

Abstract The caudal mesenteric ganglion (CaMG) is a prevetrebral ganglion which provides innervation to a number of organs in the abdominal and pelvic cavity. The morphology of CaMG and the chemical coding of neurones in this ganglion have been described in humans and many animal species, but data on this topic in the sheep are entirely lacking. This prompted us to undertake a study to determine the localization and morphology of sheep CaMG as well as immunohistochemical properties of its neurons. The study was carried out on 8 adult sheep, weighing from 40 to 60 kg each. The sheep were deeply

Abstract:
Obesity is taking on pandemic proportions. The laws of thermodynamics, however, remain unchanged, as energy will be stored if less energy is expended than consumed; the storage is usually in the form of adipose tissue. Several neural, humeral and psychological factors control the complex process known as appetite. Recently, a close evolutionary relationship between the gut and brain has become apparent. The gut hormones regulate important gastrointestinal functions such as motility, secretion, absorption, provide feedback to the central nervous system on availability of nutrients and may play

Consciousness is neuronal as it is based on the brain and its neural activity. This is what neuroscience tell us citing strong empirical evidence. At the same time, consciousness is ecological in that it extends beyond the brain to body and world – this is what philosophers tell us when they invoke concepts like embodiment, embeddedness, extendedness, and enactment. Is consciousness neuronal or ecological? This amounts to what I describe as “argument of inclusion”: do we need to include body and world in our account of the brain and how is that very same inclusion important for consciousness?

We describe a new generic approach for realizing neural network models. Schematically the basic system consists of a special purpose electronic integrated circuit—the neural processor (NP) and a 2-D spatial light modulator (SLM). The synaptic efficacies matrix is stored on the SLM and loaded in parallel into the NP. This is done by imaging the contents of the SLM onto an array detector which acts as the input unit of the NP. The NP processes the state of the network by using the synaptic efficacies supplied by the SLM. Several different architectures for the NP are described which enable the c

Abstract:
Free-living flatworms, planarians, are often used as a biological model to study the morphogenesis and regeneration processes, as well as structure and function of their muscle system. In this study, the spatial relationships between musculature and the nervous system were examined in planarians Girardia tigrina (Turbellaria, Platyhelminthes) using confocal laser scanning microscopy, histochemical staining of filamentous actin with fluorescently labelled phalloidin, and immunocytochemical staining of the nervous system with parasitic worm neuropeptide F antibodies. The body wall musculature co

Abstract:
We study the relationship between the arrangement of neurons and the complexity of the ReLU-activated neural networks measured by the number of linear regions. More specifically, we provide both theoretical and empirical evidence for the point of view that shallow networks tend to have higher complexity than deep ones when the total number of neurons is fixed. In the theoretical part, we prove that this is the case for networks whose neurons in the hidden layers are arranged in the forms of 1x2n, 2xn and nx2; in the empirical part, we implement an algorithm that precisely tracks (hence counts)

Abstract:
Abstract Rate of Penetration (ROP) optimization has played a key role in the economic return and value of both onshore and offshore wells by decreasing drilling time thereby increasing the net present value (NPV) of the localized field. In this study, an Artificial Neural Network (ANN) model is developed to accurately model the ROP of a well in SW Oklahoma to optimize the drilling process. A parametric study was conducted to showcase the effect of operational parameters on the ROP-ANN model and to minimize error and increase accuracy. The number of neurons and hidden layers within the model ar

ABSTRACT: Polycrystalline Diamond Compact (PDC) bit underground operating conditions identification is one of the difficulties during the drilling operation. It is of great significant for the drilling improvement and accurate construction formation to accurately identify the complex operating conditions during drilling the operation such as PDC bit wearing and stick-slip vibration, etc. In this paper, data of relationship between torque, rate of penetration (ROP) signal and weight on bit (WOB), rev were obtained through lab simulation experiment, after which, a relationship database of torque
