The performed cytogenetic analysis included 454 young Leine ewes, aged 2-8 months, coming from heterosexual twins and multiples.Out of them, the studied 431 animals had a normal diploid chromosome number - 54,XX.Leukocytic 54,XX/54,XY chimerism was identified in 23 young ewes, which makes 5.06% of the studied group of animals.

The aim of the present study was to investigate the effect of small unilateral lesions to the ventromedial portion of the prefrontal cortex on two memory functions: memory for objects and memory for object locations. Patients, who had undergone surgery of the anterior communicating artery aneurysm, and normal control subjects, participated in the study. The patients were subdivided into two groups: with and without unilateral resection of the gyrus rectus. Subjects were presented with two memory tests, that required remembering either simultaneously presented visual stimuli (object memory test; OMT) or locations of the stimuli (location memory test; LMT). In the OMT, patients with resection of the gyrus rectus were impaired in comparison to patients without resection and normal control subjects. In the LMT, the three groups did not differ from each other. Our results suggest that the ventromedial prefrontal cortex is specifically involved in memory for objects.

Verbal phonological and semantic fluencies were investigated in 24 patients with unilateral prefrontal lesions and 10 normal control subjects. Lesions were limited to small areas within either the dorsolateral (Brodmann?s area 46/9) or ventromedial (posterior part of the gyrus rectus) cortices. In a phonological fluency task, patients with lesions to the left dorsolateral region were impaired. In semantic fluency, not only the left dorsolateral group but also the two right frontal damaged groups performed worse than the control group. In agreement with previous studies, our results show that the phonological fluency is mediated by the left dorsolateral prefrontal cortex. In contrast to this, performance on the semantic fluency task depends on a wider portion of the prefrontal cortex involving the left and right dorsolateral and the right ventromedial areas.

Our previous study performed on subjects with no brain damage suggested that processes involved in the storage of sensory information are lateralized to the right hemisphere. The present research aimed at verifying this hypothesis by studying the effect of unilateral temporal lobe lesion on performance in a sensory information storage test. Seventeen patients who had undergone a unilateral temporal lobectomy for the relief of intractable epilepsy (8 subjects - left hemisphere damage, 9 subjects - right hemisphere damage) and 11 normal control subjects with no brain damage were tested. The subjects were presented with geometrical Vanderplas type figures exposed in pairs, each for 100 ms, one afther another, with short (50 ms and 500 ms) and long (3,000 ms) interstimulus intervals (ISI). The task of the subjects was to judge whether the second stimulus was the same as, smaller or bigger then the first one. The first stimulus in each pair was exposed unilaterally, randomly in the left (LVT) or right (RVT) visual field, and the second one in the center of the screen. In short ISI condition the RH-damaged group performed worse then both the control group and the LH-damaged group. In long ISI condition the RH-damaged group did not differ from the controls .On the contrary th LH-damaged group did not differ significantly from the controls in any ISI condition. The results shows that temporal lobe structures are involved in time limited storage of sensory information. Moreover, they provide further evidence for the right-hemispheric locus of this storage.

This study examined verbal and nonverbal aspects of explicit and implicit memory in a sample of 19 Parkinson's disease (PD) patients and 21 control subjects. For implicit memory evaluation, we used a Mirror Reading (MR) task employing verbal material as well as a nonverbal Serial Reaction Time (SRT) task. For explicit memory measurement we applied a word pairs task (verbal) and pairs of a Japanese ideograms task (nonverbal). The PD patients displayed impairments in the nonverbal tasks only, namely, in the SRT task and the pairs of Japanese ideograms task. No correlation between Wisconsin Card Sorting Test (WCST) scores and the results of tasks in which PD patients displayed deficits (SRT and pairs of Japanese ideograms) were discovered. Interestingly, such a correlation was found in the case of MR and words pairs tasks, which did not distinguish PD patients from control group.
