This paper describes many of the processes that exist for upregulation of the nociceptive system in response to tissue injury. The processes of peripheral and central sensitization are described. Potential interactions between the nociceptive, motor and autonomic systems are considered. The potential for psychosocial factors to in ̄uence neuroplasticity within the nociceptive system is also disc...

Pain is sensed by the activation of painful nociceptors in periphery or pain mediators, such as bradykinin, serotonin, histamine, and prostaglandin, released from damaged tissue, afferent transmission to medulla spinalis, transmission stages high centers over dorsal horn. Pain, which was seen only a warning sign past, now accepted phenomenon itself that needs be treated search for new, stronge...

Because pain often signals the occurrence of potential tissue damage, nociceptive stimuli have the capacity to capture attention and interfere with ongoing cognitive activities. Working memory is known to guide the orientation of attention by maintaining goal priorities active during the achievement of a task. This study investigated whether the cortical processing of nociceptive stimuli and th...

KEY POINTS Sleep spindle are usually considered to play a major role in inhibiting sensory inputs. Using nociceptive stimuli in humans, we tested the effect of spindles on behavioural, autonomic and cortical responses in two experiments using surface and intracerebral electroencephalographic recordings. We found that sleep spindles do not prevent arousal reactions to nociceptive stimuli and tha...

abstract  introduction: diabetic rats display exaggerated hyperalgesic behavior in response to noxious stimuli that may resemble and model aspects of painful diabetic neuropathy in humans. this study was designed to investigate the effect of nigella sativum (ns) on formalin-induced nociceptive responses (standard formalin test) in streptozotocin (stz)-induced diabetic rats.  methods: for this p...

Introduction: Nociceptive stimulus triggers escape responses in Drosophila melanogaster larvae, characterized by 360° rolling behavior along its own body axis. Therefore, it is possible to study analgesic drugs based on this stereo­typical nociceptive-like behavior. Here, we aimed develop an predictive validity test of thermal nociception through D. larvae.
 Materials and methods: We evalu...

The existence of neural opioid-mediated networks that are specific for the modulation of nociception is well established. Parallel non-opioid pathways exist, but their underlying physiology is little known. We now report that oxytocin administered intraperitoneally to rats, and intraperitoneally or intracisternally to mice has an anti-nociceptive effect, which is related to the activation of de...

Paclitaxel is an anti-microtubule agent, most widely used chemotherapeutic agent for the treatment of malignant solid tumors. However, it associated with some severe side effects including painful neurotoxicity reporting neuropathic pain and sensory abnormalities by patients during after paclitaxel therapy. Peripheral neuropathy was induced administration (4 mg/kg on days 1, 3, 5, 7). In this s...

Transient nociceptive stimuli elicit robust phase-locked local field potentials (LFPs) in the human insula. However, these responses are not preferential for nociception, as they are also elicited by transient non-nociceptive vibrotactile, auditory, and visual stimuli. Here, we investigated whether another feature of insular activity, namely gamma-band oscillations (GBOs), is preferentially obs...
