In primates, multiple corticospinal projections from the sensorimotor cortex operate in
concert to regulate voluntary action. We examined the soma distributions of all those …

The retrograde axonal transport method has been employed to identify the cell bodies of
cortical neurons projecting directly to the spinal cord in the monkey. The investigation has …

We determined the origin of corticospinal neurons in the frontal lobe. These neurons were
labeled by retrograde transport of tracers after injections into either the dorsolateral funiculus …

The corticospinal projection is considered to influence fine motor function through nearly
exclusively contralateral projections from the cortex in primates. However, unilateral lesions …

Postnatal changes in the topography of the multiple corticospinal projections in the macaque
monkey were followed using retrogradely transported fluorescent tracers, and related to the …

We examined the topographic organization of corticospinal neurons in the primary motor
cortex and in the two premotor areas on the lateral surface of the hemisphere [ie, the dorsal …

Previous anatomical work in primates has suggested that only corticospinal axons
originating in caudal primary motor cortex (“new M1”) and area 3a make monosynaptic …

We examined the topographic organization of corticospinal neurons in the four premotor
areas on the medial wall of the hemisphere of macaques. These motor areas include the …

There is considerable debate as to the relative importance, for cortical control of upper limb
movements, of direct cortico-motoneuronal (CM) versus indirect, propriospinal transmission …

The cortical connections of electrophysiologically identified locations in the body
representations in somatosensory cortex of macaque monkeys were investigated after …
