cardiovascular regulation and the endogenous analgesic system. Animals were anesthetized with α-chloralose and single cell activities were recorded by carbon-filament microelectrode and their relationships with cardiovascular activity were analyzed. In RVLM area, a total of thirty-three cells were identified as cardiovascular neurons. During one cardiac cycle, the mean discharge rate of the neurons was 1.96±0.29 and the peak activity was observed 45 ms after the systolic peak of arterial blood...

action potentials recorded from rat tibial nerve before and after topical application of mustard oil were compared. The higher the concentration of mustard oil and the longer the application time, the more powerful desensitization or conduction block was induced. From the results of the present study, it is suggested that the desensitization of the afferent fiber and sensory receptors induced by mustard oil results mainly from the conduction block of C-fiber in the primary afferent nerve.

did not change the afferent sensory transmission. Medium doses (0.01 μg) of bombesin significantly (p p<0.01) facilitated afferent sensory transmission in the 6 to 30 min post-drug period, but higher doses (0.1 μg) inhibited responsiveness of spinal trigeminal neurons in the 16 to 35 min post-drug period. The results indicate that endogenous bombesin-like peptide present in the spinal trigeminal nucleus may participate in the processing of the somatosensory information arising from the face.

novel techniques of PET and MRI, provides evidence of corresponding motor areas. Each area has its unique sources of inputs from the thalamus and from other parts of the cerebral cortex. To understand functional roles of these multiple motor areas, it is necessary to study neural activity while subjects are performing a variety of motor tasks. In view of high accuracy in spatial and temporal resolution, the analysis of single cells in relation to specific aspects of motor behavior remains to be...

current, which might reflect the changes of intracellular calcium concentration, was enhanced by dopamine. This effect was abolished by phentolamine. 5) The enhancing effect of dopamine on the Ca2+ -dependent K+ current disappeared with heparin which is known to block the action of InsP3. From these results, it is suggested that dopamine acts via InsP3-mediated Ca2+ mobilization from intracellular stores and such action potentiates the spontaneous contraction of guinea-pig gastric smooth muscle.

ito more effectively than a single application or DOG or TPA. From the above results, we have shown that ionic currents elicited by voltage pulses existed in the unfertilized eggs of mouse and hamster. There are at least two types of currents, ica and ik in mouse eggs, while three types, ica, Ca2+-dependent ik and Ca2+-independent ik exist in hamster eggs. ionic channels in these eggs may be regulated either directly by GTP and PKC or indirectly by the substances linked with GTP and PKC.

20) and the ventroposterolateral (VPL, n= 16) thalamic nucleus of awake rats. Spike triggered cross correlation histograms were constructed between pairs of simultaneously recorded neurons. Among 101 neuronal pairs analyzed, 22.7% showed correlations indicative of various functional connections among the cortical cells, two corticothalamic interactions and one thalamocortical excitatory interaction. There were also 15 cofiring activities among SI cortical cells. These functional connectivities...

of the soleus muscle and fatigue index of the medial gastrocnemius muscle in HS-ES group were not different from those of the control group. While mechanical properties of the soleus muscle examined were all significantly increased in HS-ES group compared with HS group, only contraction time and fatigue index of the medial gastrocnemius muscle were significantly increased in HS-ES group. These data indicate that intermittent electrical stimulation may be useful in prevention of muscle atrophy.

the contracture. Cd2+ suppressed the amplitude of the Na+ tee contracture dose dependently and the amplitude of Na+ free contracture almost decreased to 20% of control amplitude in the concentration of 10-4 M Cd2+. From the above results, it is suggested that Cd2+ may inhibit not only Ca2+ influx via voltage sensitive, receptor operated Ca2+ channel and Na/ca exchange but also intracellular Ca2+ release from the sarcoplasmic reticulum in the antral circular muscle of guinea pig stomach.

A total of 113 neurons was recorded in ventrolateral medulla that had the axonal projections to T2 spinal cord. Thirty four of these medullospinal cells showed spontaneous discharges and the others not. Between these two groups, rostro-caudal coordinate of the distribution from obex [4.7±0.2 (mean S.E.) mm, 4.1 0.1 mm], depth from dorsal surface (5.5±0.2mm, 4.9±0.1mm and conduction velocity (9.9±1.7m/sec, 16.7±1.9 m/sec) were significantly different (p<0.05). In spontaneously discharging...
