1 Objective To establish visualization methods of the commissural fibers in the human brain by using diffusion tensor tractography, and to investigate the coherence with known anatomy.

2 The commissural region of the main and accessory valve can be divided into the commissural region between single main valve and accessory valve, and between united main valve and accessory valve.

3 ConclusionBiological characteristic change of CAVD valvular interstitial cells might be the major reason for the thickening, calcification, and commissural fusion in CAVD valvular samples.

4 Third group was-the sensory nucleus, such as parabrachial nucleus, main sensory nucleus of the trigeminal nerve and the commissural nucleus.

5 Objective To Study the distribution of primary afferent fibers of the sciatic and pelvic nerves in the dorsal commissural nucleus(DCN) of the rat lumbosacral spinal cord.

6 The firing rates and patterns of neuronal activity in the anterior commissural nucleus (ACN) were studied on in vitro hypothalamic slices using electrophysiological techniques.
