The postulated role of the acetylcholine receptor in the formation of neuromuscular synapses during the course of embryonic development was investigated in the superior oblique muscle of white Peking duck embryos. The possibility that the number of receptors could be experimentally lowered by chronic injections of the anticholinesterase agent, neostigmine methylsulfate, was determined using 125...

The pattern of axonal terminations of individual premotoneuronal medium lead burst neurons (MLBs) has been elucidated with the help of the intraaxonal recording and horseradish peroxidase injection technique in alert behaving monkeys. These findings indicate that individual MLBs do not influence individual muscles; instead they influence groups of muscles. Horizontal medium lead burst neurons (...

Examination of 2 life masks of Abraham Lincoln's face was performed by means of 3-dimensional laser surface scanning. This technique enabled documentation and analysis of Lincoln's facial contours and demonstrated his marked facial asymmetry, particularly evident in the smaller left superior orbital rim. This may have led to retroplacement of the trochlea on the left side, leading, in turn, to ...

Brown syndrome describes the inability of a patient to perform an upward gaze while the eye is adducted due to an abnormality of the superior oblique tendon sheath complex. Use of CT in diagnosing the condition has been reported; however, the use of MR imaging has not. We describe a unique case of Brown syndrome in which the initial CT findings were normal, but MR imaging revealed the abnormali...

A rare case of possible postinflammatory fibrosis of the superior rectus and superior oblique muscles, resulting in marked hypotropia with pseudoptosis, is described, together with the surgical management.

A 9-year-old boy with systemic juvenile chronic arthritis and Brown's syndrome (limitation of elevation of the adducted eye due to limitation of movement of the superior oblique tendon) is described. The resolution in association with steroid treatment suggested a transient tenonsynovitis involving the superior oblique tendon as the cause.
