This computer modelling study on motor cortex stimulation (MCS) introduced a motor cortex model, developed to calculate the imposed electrical potential field characteristics and the initial response of simple fibre models to stimulation of the precentral gyrus by an epidural electrode, as applied in the treatment of chronic, intractable pain. The model(More)
The hypothalamic lateral tuberal nucleus (NTL) was studied in the formalin-fixed brains of five patients with Huntington's disease (HD) and in five age- and sex-matched controls. With the Klüver-Barrera (luxol fast blue/cresyl violet) and hematoxylin and eosin stains the NTL was defined by its cytoarchitectonic characteristics. The nucleus was composed of(More)
In this description of the morphology of the mouse cerebellum, the main landmarks for subdivision were the discontinuities of the cortical sheet. In certain cerebellar sulci in the posterior lobe, the cortex is absent. Within the paramedian sulcus the cortex is interrupted rostral and caudal to the copula pyramidis. Rostrally, this discontinuity between(More)
The glial system in the developing rat spinal cord was studied using immunocytochemistry. Antibodies to vimentin and glial fibrillary acidic protein (GFAP) were used. At E11, vimentin was first found in the membrana limitans externa. In the matrix layer, short vimentin protrusions were found near the membrana limitans externa at E12. In addition, vimentin(More)
The human micturition cycle is controlled by central and peripheral nervous structures and connections. In literature, no complete or generally accepted model describes the principles of micturition control. In this paper, the integration of (neuro-)anatomy, (neuro-)physiology and control theory is used to describe and model the neuronal control of the(More)
Numbers, linear density, and surface area of synaptic boutons can be important parameters in studies on synaptic plasticity in cultured neurons. We present a method for automatic identification and morphometry of boutons based on filtering of digital images using granulometric analysis. Cultures of cortical neurons (DIV8 and DIV21) were fixed and marked(More)
Neurons from the suprachiasmatic nucleus (SCN) of the hypothalamus, the site of a circadian pacemaker in mammals, were isolated from embryonic rat. After mechanical dissociation neurons were brought into culture for 1-2 weeks, using a chemically defined medium. Recordings were made from 74 bipolar neurons using two different configurations of the(More)
The origin and course of the nerval innervation of the levator scapulae and rhomboid muscles was studied in four human cadavers. Special attention was given to surgical anatomy. The levator scapulae muscle receives two small segmental nerves from C3 and C4, respectively. The rhomboid muscle receives two segmental nerves, one from C4 and the other from C5.(More)
The quality of the electrical contact between a cultured neuron and a substrate embedded microelectrode is of importance for effective transfer of an extracellular applied stimulus current to the intracellular potential. It is affected by the resistance of the seal, i.e. the gap between the cell membrane and the substrate, which restricts the leakage(More)
STUDY DESIGN The authors investigated the innervation of discographically confirmed degenerated and "painful" human intervertebral discs. OBJECTIVE To determine the type and distribution patterns of nerve fibers present in degenerated human intervertebral discs. SUMMARY OF BACKGROUND DATA The innervation of intervertebral discs has previously been(More)
