Injury to skin decreases pain thresholds and increases the pain produced by subsequent noxious stimuli. The nature of these changes, termed allodynia and hyperalgesia respectively, depends on a number of factors and has historically been studied by examining the physiological subtype of primary afferent fibers involved (see Treede et al. 1992). Now that the identification of the transient recep...
Usually Wide Dynamic Range (WDR) sensors that autonomously adjust their integration time to fit intra-scene illumination levels use a separate digital memory unit. This memory contains the data needed for the dynamic range. Motivated by the demands for low power and chip area reduction, we propose a different implementation of the aforementioned WDR algorithm by replacing the external digital m...
There are many somatosensory neurons in the hamster superior colliculus (SC); some respond to innocuous tactile stimuli, while others respond either preferentially, or solely, to noxious stimuli. Yet, there are little quantitative data describing the responses of these neurons. We sought to provide such information by relating stimulus intensity to the magnitude of the neural response using con...
Soil relative water content and seed plumpness have been shown to be the key factors affecting germination seedling growth of rice under direct drought cropping. It remains determined whether water-saving drought-resistant (WDR) conventional with same proportion response soil moisture changes. The purpose this study was investigate physiological characteristics cultivars Guangliangyou 1813 (GLY...
Dry direct-seeded rice (dry-DSR) is an efficient, resource-saving and environmentally friendly cropping system. The employment of water-saving drought-resistant (WDR) for dry direct-seeding can better meet the needs dry-direct seeding systems. However, decline in seedling emergence rate poor growth are main bottlenecks under current production. Seed treatment a sustainable effective technique t...
To clarify the functional role of the dorsal column nucleus (DCN) in nociception in rats with advancing age, single neuronal activity and substance P-like immunoreactivity (SP-LI) of the gracile nucleus (GN) were studied in aged rats (29 to 34 mo old) and adult rats (9 to 12 mo old). A total of 122 neurons [aged: 34 wide-dynamic-range (WDR), two nociceptive-specific (NS), and 32 low-threshold m...
1. This study examined the inhibitory effects of conditioning stimuli delivered to the periaqueductal gray (PAG), nucleus cuneiformis (CU), nucleus raphe magnus (NRM), nucleus reticularis gigantocellularis (NGC), and nucleus reticularis magnocellularis (NMC) on functionally identified neurons of the lumbar spinal cord dorsal horn in chloralose-anesthetized or decerebrate cats. 2. Neurons were c...
