The rat is quite immature at birth and a rapid maturation of motor behavior takes place during
the first 2 postnatal weeks. Lumbar motoneurons undergo a rapid development during this …

The adult pattern of locomotion is observed at the end of the second postnatal week in the
rat. The in vitro spinal cord isolated from immature rats has served as a valuable preparation …

The central pattern generators (CPGs) for locomotion, located in the lumbar spinal cord, are
functional at birth in the rat. Their maturation occurs during the last few days preceding birth, …

GABA and glycine are excitatory in the immature spinal cord and become inhibitory during
development. The shift from depolarizing to hyperpolarizing inhibitory postsynaptic potentials (…

Motor behaviors of some species, such as the rat and the human baby, are quite immature
at birth. Here we review recent data on some of the mechanisms underlying the postnatal …

Serotonin (5-HT) plays an important role both in the development and in the recovery of
locomotion after spinalization in vertebrates. We investigated the contribution of the serotonergic …

Bicuculline is the most commonly used GABA A receptor antagonist to investigate the contribution
of these receptors in motor control. However, this compound has been shown recently …

The present study was carried out to characterize anatomically the vestibulospinal (VS)
system of lampreys. Cobalt‐lysine or Texas Red dextran amines were applied in vitro to the …

The distribution of vestibular primary afferents as well as their relationship with vestibulospinal
and other brainstem neurons were studied in lampreys using anatomical tracers. Afferents …

The gray short-tailed opossum Monodelphis domestica is born in a very immature state (eyes
and ears closed, budlike hindlimbs, etc.) 14 days post-coitum, but it can locomote with its …
