Selective Inhibition Mediates the Sequential Recruitment of Motor Pools

Locomotor systems generate diverse motor patterns to produce the movements underlying behavior, requiring that motor neurons be recruited at various phases of the locomotor cycle. Reciprocal inhibition produces alternating motor patterns; however, the mechanisms that generate other phasic relationships between intrasegmental motor pools are unknown. Here, we investigate one such motor pattern i...

Met Signaling Is Required for Recruitment of Motor Neurons to PEA3-Positive Motor Pools

Motor neurons in the spinal cord are grouped into motor pools, each of which innervates a single muscle. The ETS transcription factor PEA3 is a marker of a few such motor pools. Here, we show that pea3 is first induced by GDNF in a caudal subset of the motor neurons that will constitute the pea3+ population. Expansion of the pea3 domain subsequently occurs by recruitment of neurons from more an...

Recruitment of spinal motor pools during voluntary movements versus stepping after human spinal cord injury.

We investigated the activation of lower limb motor pools by supraspinal and spinal networks after human spinal cord injury (SCI). We compared electromyographic (EMG) activity from six muscles during voluntarily attempted non-weight-bearing single-joint movements, multijoint movements approximating stepping in a supine position, and weight-bearing stepping on a treadmill with body weight support...

Glycinergic "inhibition" mediates selective excitatory responses to combinations of sounds.

In the mustached bat's inferior colliculus (IC), combination-sensitive neurons display time-sensitive facilitatory interactions between inputs tuned to distinct spectral elements in sonar or social vocalizations. Here we compare roles of ionotropic receptors to glutamate (iGluRs), glycine (GlyRs), and GABA (GABA(A)Rs) in facilitatory combination-sensitive interactions. Facilitatory responses to...

Selective inhibition of pyrimidine synthesis and depletion of nucleotide pools by N-(phosphonacetyl)-L-aspartate.

poration of these compounds into pyrimidines is inefficient (27). Evidence concerning the degree of inhibition of aspartate transcarbamylase produced in animals by PALA treatment was obtained by Yoshida et ai. (27), who found that the specific activity of aspartate transcarbamylase in extracts of spleens from animals treated with PALA was only 20% of that found in control mouse spleen. The resi...
