Santiago Ramón y Cajal described a number of somatosensory structures, including several associated with pain, in his major work on the Histology of the Nervous System of Man and Vertebrates. Our knowledge of such structures has been considerably expanded since Cajal because of the introduction of a number of experimental approaches that were not available in his time. For example, Cajal made s...
This volume should be of value to both students and researchers interested in pain. The twenty-one papers are organized in a roughly anatomical direction, beginning at the nociceptor level, then moving through the spinal cord to the brain. Kruger and Liebeskind have done an excellent job of organizing the papers so that each topic leads into the next. After an introduction by Kruger and an over...
1. A goal of this study was to determine the sites in the diencephalon to which neurons in sacral spinal segments of rats project. Therefore, 95 neurons were recorded extracellularly in spinal segments L6-S2 of rats that were anesthetized with urethan. These neurons were activated initially antidromically with currents < or = 30 microA from a monopolar stimulating electrode placed into the cont...
Macaca nemestrina monkeys received unilateral interruption of the spinothalamic tract, producing contralateral hypalgesia and a bilateral decrease in amplitude of the flexion reflex. These effects on operant escape and reflex responses to electrocutaneous stimulation (ES) were monitored for months to evaluate relationships between the extent of each lesion and the presence or absence of recover...
Air-puff stimulation applied to a fingertip is known to exert a location-specific facilitatory effect on the size of the motor evoked potentials elicited in hand muscles by transcranial magnetic stimulation. In order to clarify its nature and the pathway responsible for its generation, we studied 27 patients with discrete lesions in the brain (16, 9 and 2 patients with lesions in the cerebral c...
