The present study was carried out to determine the effects of cocaine (0.25, 1.0, 10.0 mg/kg, i.p.) on the interactions between spontaneously active neurons within ensembles of simultaneously recorded neurons in the primary somatosensory cortex (Sl, n= 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...

The present study was designed to evaluate effects of intermittent electrical stimulation of the sciatic nerve on the atrophic response of antigravity muscles, such as the soleus (slow m.) and medial gastrocnemius (fast m.) muscles. Rats (Sprague-Dawley, 245-255g) were subjected to a hindlimb suspension and divided into three groups : one was with hindlimb suspension (MS) and another with hindlimb suspension plus intermittent electrical stimulation of the sciatic nerve (HS ES). Control group...

In urethane anesthetized cats, each vestibular semicircular canal nerve was electrically stimulated, and reflex responses of the cervical extensor and flexor (the splenius capitis and sternomastoid muscles) were recorded by means of electromyography. Stimulation of a unilateral (anterior, horizontal or posterior) canal nerve elicited excitation of the contralateral cervical muscles and inhibition of the ipsilateral ones; during the canal nerve stimulation, the two muscles in one side of the neck...

R wave histogram of unit and spike triggered averaging of sympathetic nerve discharge (SND) were used to define sympathetic related cell. 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,...

The effects of noradrenaline on the spontaneous contraction recorded from a strip of mucosa-free antral circular muscle were studied in the guinea-pig stomach, and the changes in slow waves and membrane resistance were analyzed in order to elucidate the mechanism for the excitatory response to noradrenaline. Electrical responses of circular muscle cells were recorded using glass microelectrodes filled with 3 M KCI. Electrotonic potentials were produced to estimate membrane resistance by the...

the antral circular muscle strips serotonin did not affect the slow wave even at the disappearance of spontaneous contractions. On the contrary it increased the amplitude of the slow wave, when the spike component was potentiated and the second component was inhibited. 6) In the antral circular muscle strips the membrane potential was slightly hyperpolarized, but the membrane resistance was not changed. From the above results following conclusions could be made. 1) Serotonin inhibits spontaneous...

The change of the acridine orange absorbance was used to monitor the formation and/or dissipation of a pH gradient in microvillous membrane vesicles (MVV) isolated from human term placenta. Under Na+ efflux conditions, an acidification of the intravesicular space occured and it was completely inhibited by 0.1 mM amiloride. Under K+ efflux conditions, an acidification of the intravesicular space occured and it was potentiated by valinomycin or FCCP. An inwardly directed chloride gradient also...

bombesin의 생물학적 활성중 하나는 위장관의 평활근을 수축시키는 작용이다. 그러므로, 본 실험에서는 bombesin이 위장관의 운동성과 관계가 깊은 평활근의 전기적 활동에 미치는 영향과 신경기전을 밝히고자 하였다. 고양이 60마리로부터 urethane마취하에 위를 적출한 다음 대만 쪽에서 체부와 유문부가 포함된 평활근 절편을 얻었으며 또한 체부에서 윤상근 절편을 얻었다. 평활근 절편을 Krebs-Ringer 용액으로 채워진 기록용기에 넣고 Ag-AgCl전극을 사용하여 체부와 유문부에서 서파를 기록하는 한편 윤상근 절편의 자발적 수축을...

10 ~ 50V$, 기간 50 ~ 100 μs 되는 자극파를 주어 신경-근 부위의 접합부 전압을 기록하여 다음과 같은 결과를 얻었다. 1) 위저부에서는 흥분성 접합부 전압이, 유문동에서는 억제성 접합부 전압이 기록되었고 유문동의 억제성 접합부 전압은 atropine(10-6 M)과 guanethidine(5 X 10-6 M)을 동시 처치했을 때 영향을 받지 않았다. 2) 세포외 Ca2+ 농도를 높였을 때(7 mM)는 억제성 접합부 전압의 크기가 증가하고 세포외 Mg2+ 농도를 높였을 때(5 mM)와 verapamil(10-5 M)을 주었을 때는 억제성 접합부 전압의 크기가 감소하였다. 3)...
