Abstract The angles of the joints of the hindlimb and the electromyographical activity of the hindlimb muscles were recorded during locomotion in mesencephalic and thalamic cats. ElectricalExpand
Neurophysiology of locomotor automatism.
TLDR
Although general features of the system controlling locomotion are more or less clear, many questions are not yet answered; it is unknown what relative contributions to motoneuronal activity are made by proprioceptive reflexes versus influences from the automatism of stepping. Expand

  • 13 November 1972
TLDR
The activity of vestibulospinal neurons giving axons to the lumbosacral spinal cord was recorded during locomotion in mesencephalic and thalamic cats and periodic alternations of this activity in relation to the locomotor cycle (modulation) were observed in cats with intact cerebellum. Expand
Activity of reticulospinal neurons during locomotion in the freely behaving lamprey.
TLDR
Different aspects of locomotor activity-initiation and termination, vigor of locomotion, steering and equilibrium control-are well reflected in the mass activity of the larger RS neurons. Expand
Activity of Different Classes of Neurons of the Motor Cortex during Postural Corrections
TLDR
Activity of neurons in the motor cortex is recorded in awake rabbits while animals maintained balance on a platform periodically tilting in the frontal plane and this finding suggests that theMotor cortex is involved in postural control. Expand
Postural control in the rabbit maintaining balance on the tilting platform.
TLDR
It was found that rabbits can effectively maintain the dorsal-side-up body posture when complex postural stimuli are applied, i.e., asynchronous tilts of the platforms supporting the anterior and posterior parts of the body. Expand
Pharmacologically induced elements of the hunting and feeding behavior in the pteropod mollusk Clione limacina. I. Effects of GABA.
TLDR
Injection of gamma-aminobutyric acid (GABA) into the hemocoel of the intact Clione evoked some essential elements of the hunting and feeding behavior, i.e., protracting the tentacles, opening the mouth, and triggering the rhythmic movements of the buccal mass. Expand
Neural bases of postural control.
TLDR
The body posture during standing and walking is maintained due to the activity of a closed-loop control system: its functional organization, the distribution of postural functions in different parts of the central nervous system, and theActivity of neuronal networks controlling posture. Expand
Encoding and decoding of reticulospinal commands
TLDR
It is suggested that commands for initiation of locomotion and regulation of its vigour, encoded as the value of bilateral RS activity, are decoded in the spinal cord by integrating all RS signals arriving at the segmental locomotor networks. Expand
