The purpose of this study was to trace the course of the posterior commissure and to mark out its parts. To carry out this task, 5 series of sections of the dog's brain were made. These were: 3 series of sections in the frontal, sagittal, and horizontal planes, stained by the Weigert-Wolters method, and, 2 series of sections stained, using alternately Kliiver's and Nissl's methods. Topography o...

This study assesses the effects of age on the composition of the anterior commissure of the rhesus monkey. The anterior commissures of nine young (5-10 years), five middle-aged (15-20 years), and eight old (25-35 years) monkeys were examined by light and electron microscopy. In all, 90-95% of the nerve fibers in the anterior commissure are myelinated. With age, the structure of the myelin sheat...

The anterior commissure, a fiber tract that is larger in its midsagittal area in women than in men, was examined in 90 postmortem brains from homosexual men, heterosexual men, and heterosexual women. The midsagittal plane of the anterior commissure in homosexual men was 18% larger than in heterosexual women and 34% larger than in heterosexual men. This anatomical difference, which correlates wi...

In this study the role of anterior commissure was explained in the formation of secondary mirror focus during experimental temporal lobe epilepsy. The experiments were conducted on 12 adult male rabbits. Metallic cobalt powder was implanted unilaterally into basal amygdala as an epileptogenic agent. For the EEG recording bipolar electrodes of insulated nichrome wire were implanted into basal, m...

OBJECTIVES/HYPOTHESIS Anterior commissure involvement is considered to be a risk factor for poorer outcomes after transoral laser cordectomy (TLC) for early glottic cancer. The objective of this study was to determine the outcomes and relevance of the tumor-node-metastasis (TNM) classification in a large series of patients with early glottic cancer involving the anterior commissure treated by T...

Introduction: Laryngeal squamous cell carcinoma (SCC) can invade the thyroid gland leading to unnecessary thyroidectomies with subsequent hypothyroidism and hyperparathyroidism. Thus, clinicopathological variables should be defined in order to predict thyroid gland invasion preoperatively.   Materials and Methods: We performed a retrospective analysis of 1,465 patients with laryngeal SCC referr...

The anterior commissure forms the first axon connections between the two sides of the embryonic telencephalon. We investigated the role of the transmembrane receptor Frizzled-3a in the development of this commissure using zebrafish as an experimental model. Knock down of Frizzled-3a resulted in complete loss of the anterior commissure. This defect was accompanied by a loss of the glial bridge, ...
