“…Nervous fibres dominate in the superficial layer I. Layer II -the middle one, has the most densely arranged neurons, layer III -the deepest, contains neurons, which are loosely arranged. Neurons in layer II are divided into lying superficially pyramidal neurons, identified as SP (superficial pyramidal) and cells identified as SL (semilunar cells) responsible for odour (2,23). These cells differ from each other by having different sensitivity threshold.…”

The aim of the study was to compare the immunoreactivity and distribution of two kinds of oestrogen receptors within the nerve tissue of the posterior part of the piriform cortex, as well as their localisation within nerve cells. The studied material consisted of 12 brains of sexually mature rabbit males weighing 3-4 kg. In order to prove the presence of α and β receptors, Er-α and Er-β antibodies were used. The examinations showed the presence of Er-α and E-rβ receptors in all layers of the piriform cortex, however, mainly in the II nd and III rd layer. The reaction occurred in the nucleus and cytoplasm of neurons. The obtained results can imply the influence of oestrogen on the functions of the examined brain area in rabbits, which in human is responsible for perception and categorisation of odour.

The functioning and connectivity of the olfactory system, which produces our sense of smell, has recently been attracting increased attention from neuroscientists, particularly since the award of the 2004 Nobel Prize to Buck and Axel for their research in this field. To study the olfactory system further, it would be advantageous to develop methods for keeping isolated brain tissue viable for long periods of time. This study examines the morphology, electrophysiology and survival of cells in brain slices that have been kept in culture, in comparison to acute slices. We prepared parasagittal slices that contained the olfactory bulb (OB), the piriform cortex (PC) and the lateral olfactory tract (LOT). Such slices would be particularly useful in studies that depend upon intact connectivity between the OB and the PC. In this study, we identified differences in the synaptic and intrinsic properties between pyramidal neurons in the acute and cultured slices. Also, the GABAergic interneurons appear not to have been affected. Therefore, we concluded that these slices would be suitable for use in studying some aspects of the olfactory system but only once the differences identified have been investigated further.
