Feedback signal from motoneurons influences a rhythmic pattern generator
(Society for Neuroscience, 2017-09-20)
Motoneurons are not mere output units of neuronal circuits that control motor behavior but participate in pattern generation. Research on the circuit that controls the crawling motor behavior in leeches indicated that ...
From synapses to behavior: development of a sensory-motor circuit in the leech
(John Wiley & Sons Inc, 2008-05)
The development of neuronal circuits has been advanced greatly by the use of imaging techniques that reveal the activity of neurons during the period when they are constructing synapses and forming circuits. This review ...

Widespread inhibition proportional to excitation controls the gain of a leech behavioral circuit
(Cell Press, 2008-01)
Changing gain in a neuronal system has important functional consequences, but the underlying mechanisms have been elusive. Models have suggested a variety of neuronal and systems properties to accomplish gain control. Here, ...
Effect of a nonspiking neuron on motor patterns of the leech
(American Physiological Society, 2012-04)
Premotor and motoneurons could play regulatory roles in motor control. We have investigated the role of a premotor nonspiking (NS) neuron of the leech nervous system in two locomotive patterns: swimming and crawling. The ...

(Asociación Herpetológica Argentina, 2016-09)
First report of the leech Oxyptychus inexpectatus predating on Pleurodema somuncurense and Rhinella arenarum in the Somuncura plateau, Rio Negro, Argentina. Amphibians are among the most threatened vertebrates worldwide, ...
Política linguística para as línguas oficiais em Timor-Leste : o português e o Tétum-Praça
(Universidade Federal Fluminense, 2012)
O presente artigo tem como objetivo analisar a política e o planejamento linguísticos para o português e o Tétum-Praça em Timor-Leste, já que ambas as línguas são asseguradas pela cons-tituição do país, que data de 2002, ...
