A possible role of the cerebellum in detecting and recognizing event sequences has been proposed. The present study sought to determine whether patients with cerebellar lesions are impaired in the acquisition and discrimination of sequences of sensory stimuli of different modalities. A group of 26 cerebellar patients and 26 controls matched for age, sex, handedness, musicality, and level of education were tested. Auditory and visual sensory sequences were presented out of different sensory pattern categories (tones with different acoustic frequencies and durations, visual stimuli with different spatial locations and colors, sequential vision of irregular shapes) and different ranges of inter-cue time intervals (fast and slow). Motor requirements were small, with vocal responses and no time restrictions. Perception of visual and acoustic stimuli was generally preserved in patients and controls. The number of errors was significantly higher in the faster tempo of sequence presentation in learning of sequences of tones of different frequencies and in learning of sequences of visual stimuli of different spatial locations and different colors. No difference in tempo between the groups was shown. The total number of errors between the two groups was identical in the sequence conditions. No major disturbances in acquisition or discrimination of various sensory sequences were observed in the group of cerebellar patients. Sequence learning may be impaired only in tasks with significant motor demands. 相似文献

Number magnitude is assumed to be holistically represented along a single mental number line. Recently, we have observed a unit-decade-compatibility effect which is inconsistent with that assumption (Nuerk, Weger, & Willmes, 2001). In two-digit Arabic number comparison, we have demonstrated that compatible comparisons in which separate decade and unit comparisons lead to the same decision (32_47, 3 < 4 and 2 < 7) were faster than incompatible trials (37_52, 3 < 5, but 7 > 2). Because overall distance was matched, a holistic model could not account for the compatibility effect. However, one could argue that the compatibility effect was due to the specific vertical perceptual arrangement of the two-digit numbers in Nuerk et al.'s (2001) experiment where the decade digits and unit digits were presented column-wise above each other. To examine this objection, we studied the perceptual generality of the compatibility effect with diagonal presentation. We replicated the compatibility effect with diagonal presentation. It is concluded that the compatibility effect is not due to encoding characteristics imposed by the perceptual setting of the original experiment. In particular, the assumption of an overall analog magnitude representation for two-digit numbers is not consistent with these data. 相似文献

The purpose of this investigation was to study the effects of Medical Resonance Therapy Music (MRT-Music) upon autonomous
innervation of cerebral arteries by examining slow spontaneous oscillations of cerebral blood flow (SSO) using transcranial
Doppler ultrasound (TCD). TCD detects SSO with 3–9 cycles per minute (M-waves) and 0.5–2 cycles per minute (B-waves). The
SSO are caused by rhythmic diameter changes of the medium and small cerebral arteries. Six patients aged 24–65 years suffering
from tension headache were treated with MRT-Music. Twelve additional patients were examined with TCD only to register SSO
for further spectral analysis.
After fast Fourier transformation four groups of peaks were registered on the SSO spectra, divided into four rhythms: A. 0.0–0.02
Hz, B. 0.02–0.033 Hz, C. 0.06–0.09 Hz, D. 0.09–0.15 Hz and an intermediate diapason of 0.034–0.059 Hz.
Spectral analysis of the SSO showed changes between initial and final amplitude peaks in all patients. In contrast to A-,
B-and D-rhythms, the reduction of peaks in the C-diapason was statistically significant (31–60%, P 3D0.04, CI 3D95%) for patients
treated with MRT-Music. All patients treated with the MRT-Music reported a relief of headache while and after treatment. 相似文献

Music is an ancient method for healing. In the year 550 B.C., Pythagoras from Greece developed a concept for the use of music
in medicine, esteeming music higher than many other medical treatments. The Medical Resonance Therapy Music (MRT-Music) of
the German classical composer and musicologist Peter Huebner is built on this concept of Pythagorean music medicine. Its therapeutic
effect may be best explained by the natural phenomenon of resonance between the harmony laws of the microcosm of music and
the biological laws of the body. Results received after application of MRT-Music indicate multiple positive effects on the
organism of pregnant women both with a healthy pregnancy as with a pathologic one, reducing the rate of premature births very
effectively. Furthermore, MRT-Music came out to be an effective method in the complex therapy of late gestoses and a nearly
irreplaceable method for preoperative preparation of pregnant woman for caesarean section. It demonstrated a powerful anti-stress
effect and allowd to reduce the amount of administered pain-killers to pregnant women by the factor 1.5 to 2.0 thus reducing
the negative pharmacological load to the foetus. It furthermore reduced labour time and shortened hospital stay. It helped
to create optimal conditions for the course of pregnancy and heightened pain sensitivity threshold by means of improving the
functional, hormonal, and psycho-emotional conditions of pregnant and lying-in women. Thus, the labour process became more
natural, the delivery non-traumatic, and motherhood more happy and safe. 相似文献

Using the metaphor of “a long run’ to describe our progress in suicidology, the author looks back to discuss important concepts that have become well established, such as clues to suicide, ambivalence, crisis services, suicide consultations, and psychological autopsies. An example is the psychological autopsy of Marilyn Monroe. Follow-up studies of crisis center clients have indicated that chronically suicidal clients are at the greatest risk of suicide. Recommendations for the long-term treatment of such patients are provided. Research on youth suicide is reported. Finally, the author looks ahead toward new developments in training and treatment. 相似文献

To determine changes in rates of drug ingestions in 10–14 year old children in our country, a retrospective chart review of 10–14 year olds hospitalized for drug ingestion between 1993–1995 and 2000–2004 was performed. Odds ratios and Chi‐square were used for analyses. From 1993–1995 there were 92.8 ingestions/100,000 children/year; from 2000–2004 there were 63.3 ingestions/100,000 children/year. More males ingested in 2000–2004 than 1993–1995 (26.3% vs. 14.2% O.R. 2.15 [1.19, 3.92]). More patients took psychiatric medications in 2000–2004 than 1993–1995 (38.9% vs. 27.0%, O.R. 1.72 [1.06, 2.80]). More patients ingested SSRIs in 2000–2004 than 1993–1995; fewer ingested tricyclics. Hospitalization rates for drug ingestions have decreased. There has been a change in drug ingested, and more males are ingesting drugs. 相似文献

Different methods of poisoning used by individuals with the diagnosis of parasuicide admitted to the Loghman Hospital, Tehran, from 2000 to 2004 were investigated, with particular focus on gender and age differences. Drugs, pesticides, and other agricultural chemicals (women: 12.7%, men: 9%) were the most commonly used methods. In males, the percentage of use of drugs increased with age, but the frequency of pesticides use decreased with age. In females, drugs were most often used in the youngest age group, whereas the use of pesticides was lowest in the youngest age category. Females outnumbered males, especially in the youngest age group of 10 to 19 years olds. Drugs and pesticides were the substances used most often for parasuicide in each age group regardless of gender. 相似文献
