The output of a neuronal network results generally from both the properties of the component neurons and their synaptic relationships. This article aims at synthesizing various results obtained on the neural network generating locomotion in...
Modulation and dynamic specification of motor rythm-generating circuits in crustacea [0.03%]

The operation of central pattern generators (CPGs), oscillatory neural circuits responsible for rhythmic motor behavior, is now known to depend both on the synaptic interactions between constituent neurons and their intrinsic membrane prope...

Three types of ionic current essentially determine the firing pattern of nerve cells: the persistent Na+ current, the M current and the low-voltage-activated Ca(2)+ current. The present article summarizes recent experiments concerned with t...
Pharmacological induction of rhythmical activity and plateau action potentials in unmyelinated axons [0.03%]

The physiological function of the axon is to conduct short all-or-none action potentials from their site of initiation (usually the cell body) to the synapse. To ensure this function, both passive and active biophysical properties of the ax...
Anticipatory responses to a self-applied load in normal subjects and hemiparetic patients [0.03%]
正常人和偏瘫患者预见性地对自施负重产生的反应

N Bennis et al.
A bimanual loading task was studied in eight right-handed normal subjects and nine hemiparetic patients in order to detect anticipatory adjustments and to analyse the reflex and voluntary, responses induced by the perturbation. The left for...
Descending antinociceptive mechanisms in the brainstem: their role in the animal's defensive system [0.03%]

The identification of specialized mechanisms in the mammalian brainstem that function to inhibit the rostral transmission of nociceptive (pain-related) information in the spinal cord led to an explosion of research into the neuroanatomical ...
Structural and pharmacological aspects of the GABAA receptor: involvement in behavioral pathogenesis [0.03%]

A brief review is presented of investigations of a novel family of synaptic vesicle proteins, the cysteine string proteins (csps). Studies of csp mutants in Drosophila reveal that csps are crucial components of the excitation-secretion mach...
