چکیده

The distribution of lipofuscin in the perikarya of Purkin je cells of vermal and hemispheric lobules has been determined quantitatively in 7 rats, 30-38 months old, by the point-counting method. On the basis of morphologically and statistically significant differences a pigmentarchitectonics of the cerebellar cortex is established. The Purkinje cells of lobule VIa (Larsell 1952) are extremely lipofuscin-rich. The Purkinje cells of the hemispheres, lobules V, Vlb + c and VII contain considerable amounts of a finely granular lipofuscin, the Purkinje cells of lobules I-III and VIIIIXa a globular type of lipofuscin. The Purkinje cells of sublobule XI d c and X are lipofuscin-poor cells. Three types of lipofuscin ha ve been identified in the light microscope.

Stereological Estimation of Granule Cell Number and Purkinje Cell Volume in the Cerebellum of Noise-Exposed Young Rat

In spite of the existing reports on behavioural and biochemical changes related to the cerebellum due to noise stress, not much is known about the effect of noise stress on the neuronal changes in the cerebellum. The present study aims at investigating the effects from one week noise exposure on granule cell number and Purkinje cell volume within the neonate rat cerebellum.15-day-old male Wista...

An inward current induced by a putative cyclic nucleotide-gated channel in rat cerebellar Purkinje neurons

The roles of cyclic nucleotide-gated (CNG) channels in sensory transduction have long been recognized. More recent studies found that CNG channels are distributed in multiple brain regions involved in memory and learning, including the cortex, hippocampus and cerebellum. These findings suggest that their functions are not limited to sensory perception, but also to neuronal plasticity phenomena,...

The effect of cabergoline and levetiracetam on the histological and stereological structure of the cerebellar cortex, hippocampal and cerebellum in a model of PTZ-induced seizure kindling in rats

Background: Seizure is a chronic neurological disease that may have non-neurological origins such as astrocytes and microglia. Objective: The aim of this study was to investigate the effect of alone and co-administration of cabergoline and levetiracetam on the histological and stereological structure of the cerebral cortex, hippocampus and cerebellum following chronic seizures in rat. Methods...
