A patient with giant cell arteritis and ischaemic optic neuropathy developed bilateral tonic pupils. This pupillary abnormality may result from ischaemia of the ciliary ganglia. Despite the propensity for patients with giant cell arteritis to develop vascular occlusions in the eye and orbit, tonic

Arachnoid granulations are common incidentally detected small dural lesions which are usually asymptomatic and follow cerebrospinal fluid density/signal intensity on CT/MRI. Such lesions reaching a size of more than 1 cm are termed as giant arachnoid granulations (GAGs) which have been previously

BACKGROUND Arteriovenous fistulas (AVF) are rare vascular lesions of the brain that differ from arteriovenous malformations as they present a direct connection between artery and vein, without interposition of the nidus. They are fed by one or more arterial branches, with a single draining vein.

The effects of various ergot alkalids and related substances on the neuronal excitability were examined using a spontaneously firing neuron (PON, periodically oscillating neuron) identified in the suboesophageal ganglia of the African giant snail (Achatina fulica Férussac). Of the substances

Introduction Epidermoid tumors represent approximately 0.3 to 1.8% of all intracranial brain tumors. Only 1.5% of all intracranial epidermoid cysts (ECs) invade the brain and secondary epilepsy is extremely rare. Since August 2014, a 59-year-old male smoker had been presenting bad smell feelings,

Beroë muscle fibers are single cells which may be 20-40 micrometer in diameter in mature specimens. Longitudinal muscles may be 6 cm or more long. There is no striation pattern and the muscles were observed to contract in a tonic fashion when stretched. They are innervated by a nerve net, and

Labeled or otherwise identified neurons of the crayfish lateral giant escape reaction circuit were examined electron microscopically and the findings compared to expectations from physiology. Terminals of primary afferents contained clear, approximately 45 nm, irregularly round synaptic vesicles,

The uropods of decapod crustaceans play a major role in the production of thrust during escape swimming. Here we analyse the output connections of a pair of giant interneurones, that mediate and co-ordinate swimming tail flips, on motor neurones that control the exopodite muscles of the uropods. The

We report a case of a 70-year-old man harboring a wide-necked thrombosed giant aneurysm of the left middle cerebral artery (MCA) on the M1 segment. The patient presented with generalized tonic-clonic seizures. A computerized tomography scan showed a calcified aneurysmal wall with perianeurysmal

Cellular electrophysiological signatures of Parkinson's disease described in the pharmacological 6-hydroxydopamine (6-OHDA) animal models of Parkinson's disease include spontaneous repetitive giant GABAergic currents in a subpopulation of striatal medium spiny neurons (MSNs), and spontaneous

1. Electrophysiological and microinjection methods were used to examine the role of cyclic AMP-dependent protein kinase A (PKA) in regulating transmitter release at the squid giant synapse. 2. Excitatory postsynaptic potentials (EPSPs) evoked by presynaptic action potentials were not affected by

The intrinsic membrane properties of giant neurons of the caudal pontine reticular nucleus (PnC) were evaluated in a rat brain slice preparation. These neurons show low RP levels, long membrane time constants, low membrane resistance, tonic AP firing, and a lack of rectification behavior. The

The semimembranosus (SM) and triceps brachii (TB) muscles from wild pigs native to Florida. USA, were evaluated for histological characteristics. All three fiber types were present in both muscles in varying proportions, reflecting differences between tonic and phasic functioning muscles. Typical

Intracellular recordings were made in vivo from 9 giant aspiny neurons in the neostriatum of urethane-anesthetized rats. The cells were identified by intracellular staining with HRP or biocytin. The neurons exhibited morphological features typical of neostriatal cholinergic interneurons. Six of the
