Activation of the central pattern generators for locomotion by serotonin and excitatory amino acids in neonatal rat.
1. The role of serotonin (5‐HT) and excitatory amino‐acids (EAAs) in the activation of the neural networks (i.e. the central pattern generators) that organize locomotion in mammals was investigatedExpand

Localization and organization of the central pattern generator for hindlimb locomotion in newborn rat
An in vitro preparation of newborn rat isolated brainstem/spinal cord was used in order to locate the spinal network responsible in mammals for producing patterned locomotor activity. The spinal cordExpand

Load-regulating mechanisms in gait and posture: comparative aspects.
How is load sensed by receptors, and how is this sensory information used to guide locomotion? Many insights in this domain have evolved from comparative studies since it has been realized that basicExpand

Oscillatory properties of the central pattern generator for locomotion in neonatal rats.
1. The oscillatory properties of the lumbar spinal networks that generate locomotor activity in mammals were studied. These experiments were performed on an in vitro isolated spinal cord preparationExpand

Central control components of a ‘simple’ stretch reflex
The monosynaptic stretch reflex is a fundamental feature of sensory-motor organization in most animal groups. In isolation, it serves largely as a negative feedback devoted to postural controls;Expand

Role of gravity in the development of posture and locomotion in the neonatal rat
This report describes the early motor behaviour in the neonatal rat in relation with the maturation of sensory and motor elements of the central nervous system (CNS). The role of vestibularExpand

Differential maturation of motoneurons innervating ankle flexor and extensor muscles in the neonatal rat
The first postnatal week is a critical period for the development of posture in the rat. The use of ankle extensor muscles in postural reactions increases during this period. Changes in excitabilityExpand

Motor pattern analysis in the shore crab (Carcinus maenas) walking freely in water and on land
To whom reprint requests should be addressed. Neuromuscular activity underlying lateral walking was studied in the shore crab Carcinus maenas . Electromyograms (EMGs) were recorded from legs on bothExpand

Decapod Crustacean Leg Coordination during Walking
Crustacean walking has only recently been subjected to intensive investigation by modern behavioral and neurophysiological techniques (Evoy and Fourtner, 1973a; Barnes, 1975b; Evoy and Ayers, 1980).Expand
