Publisher Summary This chapter discusses the stimulation-produced antinociception (SPA)
and shows the involvement of the periaqueductal gray matter (PAG) and the nucleus raphe …

The electrical stimulation of the occipital (OC) or retrosplenial (RSC) cortex produces
antinociception in the rat tail-flick and formalin tests. This study examined the antinociceptive …

The anterior pretectal nucleus has been described as part of the visual pretectal complex.
However, several electrophysiological and behavioural studies showed that this area is …

Previous studies have shown that stimulation of the rat anterior pretectal nucleus (APtN)
strongly depressed a spinal reflex to noxious heat without causing significant aversion or …

The descending pain inhibitory system (DPIS) associated with acupuncture analgesia (AA),
caused by low frequency stimulation of an acupuncture point, was identified by the results of …

The changes in the latency for tail withdrawal in response to noxious heating of the skin
induced by microinjection of opioid or serotonergic agonists into the anterior pretectal …

This study examined the effects of anterior pretectal nucleus (APT) conditioning stimulation
on the activity of 92 functionally identified somatosensory brainstem neurons in the …

Previous studies have indicated that the thalamic nucleus submedius (Sm), as an ascending
component, is involved in an endogenous analgesic system consisting of spinal cord-Sm …

Aims Electrical stimulation of the anterior pretectal nucleus (APtN) cauza prolonged increase
in the latency of the tail flick reflex to noxious heat (Roberts & Rees, 1986). The present …

The effects of intrathecally (it) administered opioid antagonist naloxone (Nal), adenosine
antagonist aminophylline (Aph), and γ-aminobutyric acid (GABAA)-receptor antagonist …
