Reward sites in the medial forebrain bundle (MFB) and aversive reticular sites (RET) send
projections to the medial thalamus and elicit opposite changes in intralaminar unit activity …

✓ To investigate the mechanism of analgesia noted with electrical stimulation of the thalamic
sensory relay nucleus and medial thalamus, modulations of neuronal activities in the …

In a previous study, we found that the antinociceptive effect of IT-administered morphine on
the tail-flick (TF) reflex of rats was potentiated within 1 day after spinal transection. This …

Nucleus reticularis gigantocellularis has been shown, using both behavioral and
physiological techniques, to be involved in the processing of nociceptive information in …

In the present study, the functional neuroanatomy of nigrotectal–tectonigral pathways as well
as the effects of central administration of opioid antagonists on aversive stimuli-induced …

Generalised tonic-clonic seizures, generated by abnormal neuronal hyper-activity, cause a
significant and long-lasting increase in the nociceptive threshold. The pedunculopontine …

The anterior pretectal nucleus (APtN) and the dorsal raphe nucleus (DRN) are involved in
descending pathways that control noxious inputs to the spinal cord and participate in the …

After subcutaneous injection of formalin (5%, 50 μl) into a hindpaw of rats, biphasic
excitatory nociceptive discharges were recorded extracellularly in thalamic parafascicular …

The periaqueductal gray matter (PAG) consists in a brainstem structure rich in 5‐
hydroxytryptamine (5‐HT) inputs related to the modulation of pain. The involvement of each …

The antinociceptive role of spinal serotonin (5-HT) neurons descending from 5-HT cells near
the ventrolateral surface of the medulla oblongata was investigated by stimulating these …
