Two reports have noted gross commissural
fusion in patients with ergotamine exposure), (18,19) a finding distinctly unusual for fen-phen valve disease.
We are now in a position to obtain a detailed molecular understanding of pathfinding by commissural
[connecting] axons in the gray matter of the developing mammalian spinal cord.
Two more of the eight are axons of modulatory commissural
neuron 1 (Swensen et al., 2000), but these axons do not project beyond the STG (Nusbaum et al., 1992).
In contrast, the changes observed following transcortical-transspinal PAS can potentially result from potentiation of activity of ipsilateral spinal inhibitory interneurons and commissural
interneurons, but further research is needed.
Although revered and time-honored, this scoring system has recently come under intense scrutiny, chiefly after an emerging body of literature emphasized the key role of commissural
calcification and subvalvular affection in determining a 'poor' procedural outcome (17, 18).
Under these conditions, Schaffer commissural
fibers were cut between areas CA1 and CA3.
The cardinal anatomic changes of the valve include leaflet thickening, commissural
fusion and shortening and thickening of the tendinous cords.
Damage to valve leaflets from post-rheumatic heart disease causes mitral stenosis with commissural
fusion and irregular thickening and calcification of the leaflets (17).
However, the intensive immunolabeling of the commissural
systems emerged from this background (Fig.
Diffusion weighted images were acquired employing a single-shot echo planar imaging (EPI) sequence in alignment with the anterior-posterior commissural
It was also shown the right commissural
distance to be the greatest, followed by the non-coronary and the left commissural
ones (F=3.522, p=0.025).
Among such connections, the corpus callosum (CC) is the most prominent commissural
connection, composed of callosal axons, in the brain.
