Antisera raised against neuron specific enolase (NSE), substance P, vasoactive intestinal peptide (VIP) and tyrosine hydroxylase (TH) were used to reveal nerve fibres in the wall of the canine small and large intestine. The circular muscle of the colon was innervated by nerve fibre bundles that ran parallel to the muscle throughout its thickness. A plexus of fibre bundles was found against the ...

Using a range of electrophysiological techniques, it has been possible to demonstrate impaired function in smaller calibre motor fibres and in distal large cutaneous sensory nerve fibres in both alcoholic patients without neuropathy and in those alcoholics with clinical manifestations of peripheral nerve disease. Evidence of more proximal involvement of Ia sensory fibres was obtained, but in th...

nerve fibres growing downwards into the peripheral segment, either as (i) the result of the original nerve fibres themselves growing downwards, or (2) the result of the parent axiscylinders dividing into a number of young axis-cylinders, probably, it was thought, at the first node of Ranvier above the part of the nerve fibre damaged by the lesion (Strcebe). In the latter case the young axis-cyl...

Myelination of nerve fibres normally stops at the lamina cribrosa. When it does proceed beyond the lamina cribrosa, it is believed to do so shortly after birth. A patient is recorded in whom medullated nerve fibres developed in the retina during adult life.

BACKGROUND Although nerve fibres are present in eutopic and ectopic endometrium, it is unclear whether they appear in ovarian endometriotic lesions. We investigated the presence of nerve fibres in ovarian endometriotic lesions and its correlation with clinical parameters in women with ovarian endometriosis. METHODS Histological sections of ovarian endometriotic lesions from 61 women with ovar...

Data by E. A. Blair and Erlanger on the voltage-capacity curves and the nerve impulse velocities of each of several fibres in the same nerve trunk are related to Rashevsky's equation for the velocity of transmission in nerve. The results lend support to Rashevsky's analysis. Other empirical relations between the velocity and the parameters of the excitation equations indicate the correctness of...

In the myotomal muscles of the dogfish, Scyliorhinus canicula, there are 2 major types of fibre. The red fibres at the periphery of the myotome receive a distributed en grappe pattern of innervation. There are subjunctional folds at these endings, and the nerve terminals contain vesicles around 50 nm in diameter. In contrast to this, the white twitch fibres of the myotome are innervated focally...

Electrical stimulation strategies for cochlear implants may be improved by studying temporal frequency coding in single auditory fibres and across fibres in acoustic stimulation [1]. In single nerve fibres, phase locking between action potentials and the acoustic stimulus can only be maintained at frequencies below 600 Hz. At these frequencies, the time interval between successive action potent...

Electromyography and conduction studies in motor and sensory fibres were performed in 58 patients with different types of radial nerve injury. The site of nerve injury was predicted by clinical and electromyographic findings and correlated with changes in conduction, thereby permitting a more exact classification of the type of nerve injury. In patients with Saturday-night palsy, there was cons...
