1. Record of neurons H1. / Registro dos neurônios H1.
Em um dos estágios do processamento visual da mosca - a placa lobular, uma para cada hemisfério da cabeça da mosca - nós encontramos neurônios dedicados à detecção e processamento do auto-movimento. Um destes neurônios, chamado HI, detecta o movi-mento de trás para frente na horizontal e os dois neurônios de cada lado da cabeça interagem, melhora

2. Evidence for adenosine triphosphate as an excitatory transmitter in guinea-pig, rabbit and pig urinary bladder.
1. The effects of alpha,beta-methylene ATP (alpha,beta-MeATP) on membrane properties and excitatory junction potentials (EJPs) were examined in smooth muscle cells of the guinea-pig, rabbit and pig bladder. 2. Intracellular recording with microelectrodes was used to record membrane electrical activity from the guinea-pig bladder. ATP (10(-3) M) produced a ra

3. Effects of pulse frequency on single-unit baroreceptor activity during sine-wave and natural pulses in dogs.
1. Previous studies using sine-wave pulses have shown that changes in pulse frequency do not alter single-unit activity per unit time. Since baroreceptor activity is phasic with most of the activity occurring in systole, we reasoned that the lack of effect of pulse frequency is due to the associated reciprocal change in duration of systole with sine-wave pul

4. Electrical activities of the muscle layers of the canine colon.
The spontaneous electrical and mechanical activities of the circular and longitudinal muscle layers of the canine colon were studied. The smooth muscle cells of the circular muscle layer exhibited regular, omni-present myogenic slow-wave activity at a frequency ranging from 4 to 7 c/min. With intracellular micro-electrodes, the slow-wave amplitude was 21-38
