Abstract:
:The autoradiographic [14C]2-deoxyglucose (2-DG) method was used to map the descending effects of midbrain reticular stimulation on the rat cervical spinal cord. The stimulation evoked consistently a defensive 'freezing' reaction as well as a large and highly localized increase in 2-DG uptake in the substantia gelatinosa (SG) (Rexed laminae 2-3). No stimulus-induced changes in 2-DG uptake were produced in the other regions of the spinal cord. The findings represent the first anatomical demonstration of the activating effects of midbrain reticular stimulation on the spinal cord. They also support the concept of an integrative role for the SG in descending reticular control mechanisms at the spinal cord level.
