It has been confirmed that sleep has a key role in learning and memory. Our previous study indicated that paradoxical sleep deprivation (PSD) impairs spatial learning ability of rats, and the decrease in membrane excitability of CA1 pyramidal neurons contributes to deficits in performing a spatial learning task. To investigate the further ionic mechanisms,(More)
BACKGROUND Altered Na+ channel expression, enhanced excitability, and spontaneous activity occur in nerve-injury and inflammatory models of pathological pain, through poorly understood mechanisms. The cytokine GRO/KC (growth related oncogene; CXCL1) shows strong, rapid upregulation in dorsal root ganglion in both nerve injury and inflammatory models.(More)
BACKGROUND Inflammatory processes play important roles in both neuropathic and inflammatory pain states, but the effects of inflammation per se within the sensory ganglia are not well understood. The cytokine growth-related oncogene (GRO/KC; CXCL1) shows strong, rapid upregulation in dorsal root ganglion (DRG) in both nerve injury and inflammatory pain(More)
Previous research has demonstrated that paradoxical sleep has a key role in learning and memory, and sleep deprivation interferes with learning and memory. However, the mechanism of memory impairment induced by sleep deprivation is poorly understood. The present study investigated the effect of paradoxical sleep deprivation (PSD) on spatial learning and(More)
It has been confirmed that the voltage-gated persistent sodium currents mediate the generation of subthreshold membrane potential oscillations (SMPOs) and contribute to shaping repetitive firing. Our previous study indicated that gabapentin (GBP) administration induced a dose-dependent inhibition of SMPO in chronically compressed dorsal root ganglion (CCD)(More)
Previous research has demonstrated that diabetes induces learning and memory deficits. However, the mechanism of memory impairment induced by diabetes is poorly understood. The present study investigated the effect of streptozotocin (STZ)-induced diabetes on spatial learning and memory using the Morris Water Maze. The effects of diabetes on CA1 pyramidal(More)
Previous research has demonstrated that diabetes induces learning and memory deficits. However, the mechanism of memory impairment induced by diabetes is poorly understood. Dietary fatty acids, especially polyunsaturated fatty acids, have been shown to enhance learning and memory and prevent memory deficits in various experimental conditions. The present(More)
Ectopic spontaneous discharges play a critical role for both initiation and maintenance of the neuropathic pain state. Gabapentin (GBP) has been shown to be effective in animal models of neuropathic pain as well as in chronic pain patients. To investigate the peripheral mechanisms of GBP, the effects of GBP on spontaneous discharges and subthreshold(More)
Previous research has demonstrated that diabetes induced learning and memory deficits. However, the mechanism of memory impairment induced by diabetes is poorly understood. Sprague-Dawley rats were used in the present study to investigate the effect of streptozotocin (STZ)-induced diabetes on spatial learning and memory with the Morris water maze. The(More)
