The purpose of this review was to examine three issues that limit our understanding of motor
unit physiology:(1) the range and distribution of the innervation ratios in a muscle;(2) the …

Muscle fibres have different properties with respect to force, contraction speed, endurance,
oxidative/glycolytic capacity etc. Although adult muscle fibres are normally post‐mitotic with …

The position of small metallic markers embedded within the lung parenchyma and glued to
the pleural surface of four excised right caudal dog lobes were determined during stepwise …

Social dilemmas occur when the pursuit of self-interest by individuals in a group leads to
less than optimal collective outcomes for everyone in the group. A critical assumption in the …

In a study on descending pathways from the nucleus retroambiguus (NRA) to hindlimb
motoneurons (see accompanying paper), it appeared impossible, using data from the …

The following factors underlying behavioral plasticity are discussed:(1) reflex adaptability
and its role in the voluntary control of movement,(2) degrees of freedom and motor …

Critical firing levels (CFLs) of single motor units (MUs) in the long head of the human biceps
brachii muscle were determined in combinations of two isometric tasks: flexion of the elbow …

Force-frequency and fatigue properties of motor units in muscles that control digits of the
human hand. Modulation of motor unit activation rate is a fundamental process by which the …

1. The isometric contractile properties and morphological characteristics of the muscle unit
portion of motor units were investigated in the medial gastrocnemius (MG) muscle of Fischer …

This article reviews presumed roles of recurrent inhibition in motor control, that have been
proposed over the past five decades. The discussion is structured in an order of increasing …
