The fiber projections from the dentate nucleus to the reticular formation of the brain stem in the rabbit
The projections from the dentate nucleus to the reticular formation of the brain stem in rabbit have been examined by means of the Fink-Heimer technique. The fibers arising from the dentate nucleus primarily p...

The cerebellar projection from the reticular formation of the brain stem in the rabbit
By retrograde transport of horseradish peroxidase the reticulocerebellar projections were examined in twenty-six rabbits.

Acceleration of brain tubulin formation in the optic lobe of the chick embryo by light stimulation
The effect of light exposure on the protein patterns of optic lobe and forebrain of the chick embryo was analysed by a high-resolution micro-two-dimensional polyacryamide gel electrophoresis and computerized q...

Direct projection from the dorsal hypothalamic area to the nucleus raphe pallidus: a study using anterograde transport with Phaseolus vulgaris leucoagglutinin in the rat
A hypothalamic projection to the nucleus raphe pallidus of the medulla was examined using the anterograde tracing technique based on Phaseolus vulgaris leucoagglutinin (PHA-L) in the rat. After the iontophoretic ...

The morphology and distribution of photoreceptors in the retina of Bufo marinus
The number, cell morphology and retinal distribution of rods and cones were determined in the retina of the toad, Bufo marinus. Adult animals were sacrificed, both eyes were removed and prepared for either tangen...

Anoxic block of GABAergic IPSPs
In rat hippocampal slices GABAergic IPSPs are very rapidly suppressed by anoxia (in<2 min). Both early (GABAA) and late (GABAB) components are affected. After reoxygenation, the IPSPs recover, but only slowly and...

Antidromic identification of midbrain near response cells projecting to the oculomotor nucleus
Medial rectus motoneurons carry both conjugate and vergence eye position signals. Abducens internuclear neurons, whose axons travel in the medial longitudinal fasciculus, provide these motoneurons with the maj...

Distribution of glutamine-like immunoreactivity in the cerebellum of rat and baboon (Papio anubis) with reference to the issue of metabolic compartmentation
The cellular and subcellular localization of glutamine, a major glutamate precursor, was studied by means of an antiserum raised against glutaraldehydefixed glutamine. Ultrathin sections from the cerebellar co...

Differential cellular distribution of two sulphur-containing amino acids in rat cerebellum
An antiserum to homocysteic acid was raised in rabbits. Immunogens were prepared by coupling this amino acid to bovine serum albumin by means of glutaraldehyde and paraformaldehyde. When applied to semithin or...

Distribution of glutamate-like and glutamine-like immunoreactivities in the rat organ of Corti: a light microscopic and semiquantitative electron microscopic analysis with a note on the localization of aspartate
The light- and electron microscopic localization of glutamate and glutamine in the rat organ of Corti was studied by means of antisera raised against the respective amino acids coupled to carrier proteins. The...

Expression of neuropeptides and neuropeptide mRNAs in spinal cord after axotomy in the rat, with special reference to motoneurons and galanin
The extent to which the plasticity in peptide expression observed in develo** spinal motoneurons occurs following proximal peripheral axotomy in the adult rat was examined using in situ hybridization and imm...

Magnetoencephalography using high temperature rf SQUIDs
We have developed high-critical-temperature radio-frequency Super conducting QUantum Interference Devices (SQUIDs) with step-edge grain-boundary Josephson junctions and large flux focusers. These planar device...

The ciliary ganglion of the cat: a light and electron microscopic study
The ciliary ganglia of eight healthy adult cats were studied by light and electron microscopy. The ganglion, measuring about 2 mm in length, was consistently found to be attached to the branch from the oculomo...

Upper cervical inspiratory neurons in the rat: an electrophysiological and morphological study
Upper cervical inspiratory neurons form a distinct neuronal column located near the lateral edge of the intermediate grey matter in the rostral spinal segments. Previous studies conducted in cats have demonstr...

Nicotinic cholinoceptor-mediated excitatory postsynaptic potentials in rat nucleus ambiguus
In rat brainstem slice preparations, intracellular recording from neurons (n = 39) in the compact formation of the nucleus ambiguus (AMBc) revealed spontaneous and miniature excitatory postsynaptic potentials (EP...

A functional role for nitric oxide in locus coeruleus: immunohistochemical and electrophysiological studies
Immunohistochemical analysis of the localization of nitric oxide synthase-(NOS)-like immunoreactivity revealed the presence of this enzyme in a few neuronal cell bodies and in dendritic and axonal processes wi...

Prolonged inhibition of brain nitric oxide synthase by short-term systemic administration of nitro-l-arginine methyl ester
We studied the dose-response characteristics and the temporal profile of inhibition of brain nitric oxide (NO) synthase (NOS) elicited by i.v. administration of the NOS inhibitor nitro-l-arginine methyl ester (L-...

Insidious errors in dipole parameters due to shell model misspecification using multiple time-points
Insidious errors in dipole modeling due to shell model misspecification in a spherical model were examined analyzing multiple time-points using the constraints of a commonly-used DSL (Dipole Source Localizatio...

Article
Model misspecification detection by means of Multiple Generator Errors, using the observed potential map
Due to model misspecification, currently-used Dipole Source Localization (DSL) methods may contain Multiple-Generator Errors (MulGenErrs) when fitting simultaneously-active dipoles. The size of the MulGenErr i...

DSL and MUSIC Under model misspecification and noise-conditions
The concepts of both the traditional DSL (Dipole Source Localization) and MUSIC (Multiple Signal Classification) are explained using simple vectors. DSL and MUSIC differ in the way the weighting functions are ...
