Central pattern generator for swimming in Melibe [PDF]

open access: yes, 2005
The nudibranch mollusc Melibe leonina swims by bending from side to side. We have identified a network of neurons that appears to constitute the central pattern generator (CPG) for this locomotor behavior, one of only a few such networks to be described ...

A Rare Cause of Compression Neuropathy of Upper Limbs – Ganglionic Cysts

open access: yesJournal of Orthopaedics, Trauma and Rehabilitation, 2013
We report a 51-year-old Chinese male with a ganglion in the Guyon canal causing ulnar nerve palsy and a 54-year-old Chinese male with a ganglion in the elbow causing posterior interosseous nerve (PIN) palsy. Exploration and excision of the ganglions were

Comparative analysis of numerical density of ganglion cells with certain content of lipofuscin pigment in the parts of symphatetic trunk during the aging [PDF]

open access: yesPraxis Medica, 2015
The neurons of the sympathetic trunk as well as the other nerve cells undergo of many changes during life. The most striking of these morphological changes, during normal aging, is the accumulation of lipofuscin-filled vacuoles or neuromelanin ...

Ras p21 protein promotes survival and fiber outgrowth of cultured embryonic neurons [PDF]

open access: yes, 1989
Although evidence obtained with the PC12 cell line has suggested a role for the ras oncogene proteins in the signal transduction of nerve growth factor-mediated fiber outgrowth, little is known about the signal transduction mechanisms involved in the ...

Comparative study between aspiration followed by Intralesional triamcinolone Injection, mixture of triamcinolone and hyaluronidase and surgical excision for the treatment of forearm ganglion in a medical college hospital

open access: yesMuller Journal of Medical Sciences and Research, 2022
Background: Ganglionic cysts are benign tumors of forearm commonly encountered in our day-to-day outdoor practice. This study compares the efficacy, safety, and recurrence rates of triamcinolone, a triamcinolone hyaluronidase mixture, and surgical ...

Clinical and Radiological Profile of Intraosseous Ganglion around the Ankle in Adults: A Case Series with a Review of the Literature [PDF]

open access: yesJournal of Foot and Ankle Surgery (Asia Pacific)
Intraosseous ganglia (IOGs) are benign, nonneoplastic bone lesions with histological characteristics similar to soft tissue ganglion cysts. They are commonly observed in the subchondral region. The intraosseous ganglion (IOG) is a very rare lesion. It is

Do retinal ganglion cells project natural scenes to their principal subspace and whiten them?

open access: yes, 2016
Several theories of early sensory processing suggest that it whitens sensory stimuli. Here, we test three key predictions of the whitening theory using recordings from 152 ganglion cells in salamander retina responding to natural movies.

Arachidonic Acid as a Possible Negative Feedback Inhibitor of Nicotinic Acetylcholine Receptors on Neurons [PDF]

open access: yes, 1995
Neuronal acetylcholine receptors, being highly permeable to calcium, are likely to regulate calcium-dependent events in neurons. Arachidonic acid is a membrane-permeant second messenger that can be released from membrane phospholipids by phospholipases ...
