The claustrocortical connections in the rabbit were assessed for the first time by the method of axonal retrograde transport of two fluorescent tracers (Fast Blue and Diamidino Yellow). The material consisted of 23 adult New Zealand rabbits. Projection zones of spindle-like form, connected with the precentral, postcentral, temporal and occipital cortices(More)
Meningiomas of the lateral ventricles of the brain are rare tumours, accounting for approximately 0.5–5% of all intracranial meningiomas. Their natural history and symptomatology and the possibilities of early diagnosis are presented. The intraventricular location of the slow-growing benign mass provides a compensatory mechanism in the form of reserve(More)
The claustrum is a subcortical structure lying under the insular and piriform cortices, whose function is still not clear. Although data exist on connections of the claustrum and the limbic cortex, the topography of the limbic zone in the rabbit and rat claustrum has not been studied extensively. The study was performed on 17 adult Wistar rats and 12 New(More)
A clinical analysis of 95 patients with posterior fossa tumors treated in the Department of Neurosurgery of the Medical University in Gdansk over a period of 16 years (1979–1995) is presented. The following preoperative factors were studied: localization, size and suspected type of tumor, size of the ventricular system, and presence or absence of the “halo”(More)
 The retrograde axonal transport method was used to compare the topography and organization of the visual zone of the claustrum in rat, guinea pig, rabbit and cat. First, massive Fluoro-Gold injections were placed into the primary visual cortex and the secondary areas. Experiments showed differences in the location of the visual zone among the animals under(More)
The quantitative analysis of the claustrocortical connections labeled with the fluorescent retrograde tracer Fluoro-Gold (FG) was conducted on 90 rabbits subdivided into the following age groups (P2, P7, P14, P21, P30, P60, P90, P120, P180). The equal volumes of retrograde fluorescent tracer FluoroGold (FG) were injected into the selected regions of the(More)
Spontaneous intracerebral haemorrhage carries a high mortality rate and treatment of the disease raises more questions then answers. Mass effect, ischaemia and toxicity of blood components are responsible for brain tissue damage. Initially occurring disturbances of cerebral blood flow have a temporary character and do not play a key role in the pathology of(More)
The quantitative analysis of the claustrocortical connections in the rabbit, labeled with the fluorescent retrograde tracer Fluoro-Gold (FG), was conducted by means of unbiased stereology. The FG was injected into selected regions of the motor, somatosensory, auditory and visual cortices and then a comparison of the various claustrocortical projections was(More)
Intracerebral haematoma was produced in 25 adult rats by infusion of 100 microl of autologous blood into the striatum. The animals' brains were removed at 1, 3, 7, 14 and 21 days after production of the haematoma. The TUNEL method was used to detect DNA fragmentation and TUNEL-positive cells were qualified. TUNEL-positive cells were already found on the(More)
