Study of cortical spindles during sleep in the rat.

A systematic analysis of the dorsally accessible cortical areas has been undertaken so as to study the space-time distribution, the intrinsic characteristics and the physiological appearance modalities of cortical spindles in the rat. After falling asleep, the animal presents anterior spindles of which the number, duration and amplitude increase as sleep with slow waves deepens. These spindles are fully developed during intermediate state which precedes and follows paradoxical sleep, where they are associated with a theta rhythm in the hippocampus and the visual cortex. These spindles, at their maximum in anterior regions, lose intensity as one approaches the cerebellum. Uniquely during slow wave phase of sleep, the rat presents posterior spindles which are predominant in the occipital region, are less marked in parietal and cerebellar regions and disappear in the frontal cortex. Less frequent than anterior spindles, they are significantly distinguished by their lower amplitude, higher frequency and shorter duration.

[Topographic anatomy of the ethmoid labyrinth in x-ray computed tomography].

These last years the surgical treatment of inflammatory ethmoid disease has been completely modified, with new endoscopic conservative procedures. In a preoperative phase it is mandatory to provide optimal CT imaging of the ethmoid labyrinth, and for this purpose sections perpendicular and parallel to the nasofrontal duct axis are better than axial and coronal slices. The anatomy of the ethmoid is fairly complex; however certain constant anatomic landmarks allow a systematic analysis of the ethmoid labyrinth: the unciform process, the bulla, the middle turbinate, the superior turbinate and their respective basal lamellae.
