Tritone Paradox

The tritone paradox occurs when an ordered pair of tones is presented, with each tone consisting of a set of octave-related components, and the pitch classes of the tones separated by a half-octave. Such a pattern is heard as ascending in one key, but as descending in a different key. Further, the pattern in any one key is heard as ascending by some listeners but as descending by others. It was here found that this phenomenon occurs to a highly significant extent in a general population, and that it is distributed within the population in an orderly fashion. The findings also reveal a surprising ability within the general population to utilize absolute pitch.

The Individual

In the tritone paradox, two tones are presented that are related by a halfoctave. Each tone consists of a set of octave-related sinusoids whose amplitudes are scaled by a bell-shaped spectral envelope; thus the usual cues to height attribution are missing. When listeners judge whether such tone pairs form ascending or descending patterns, judgments are related in an orderly fashion to the positions of the tones along the pitch class circle: Tones in one region of the circle are heard as higher and those in the opposite region as lower. However, listeners differ strikingly in the orientation of the pitch-class circle with respect to height. So far, the basis of the tritone paradox and the reasons for the individual differences in its manifestation have proved elusive. In the present study, a correlation is found between perception of the tritone paradox and the range of fundamental frequencies of the listener's speaking voice. To the authors' knowledge, this is the first demonstration of a close connection between the perception of a musical pattern on the one hand and the listener's speech characteristics on the other.

Absolute pitch (AP), the ability to identify and produce musical pitches without a reference point, is extremely rare and is considered to be a special ability.  Although research has focused on this topic for decades, there is no consensus about why AP only occurs in 1 out of 10.000 individuals and how it is acquired.  Therefore, the present article aims to review and reconcile the previous findings in order to understand the potential contribution of training and genetics in AP acquisition.  Based on experimental psychological and genetic findings, it is concluded that although some components of AP are implicit and exist in the general population, both early musical training and genetic factors are crucial for AP development.  This conclusion is supported by neuroscientific findings that provide evidence for differences in activations in specific brain areas between AP possessors and non-possessors.

By means of the method of polimerase chain reaction the frequency of blank allele of genes GSTP1, GSTM1, and the frequency of polymorphous alleles of gene GSTP1 in 40 pairs with habitual noncarrying of pregnancy at early stages were studied. The results of the investigation testify to the high rate of gomozygotes GSTT1 0/0 in pairs with habitual noncarrying of pregnancy in comparison with indices in general population of North-West region of Russia (37,7% and 23,3% correspondingly). The genes GSTM1, GSTT1, GSTP1 code enzymes, which take part in the second phase of xenobiotic detoxication system. Taking into consideration that protein products of these genes to significant extent determine the effectiveness of 2nd phase of detoxication (neutralization of xenobiotics by glutathione binding), we are to suppose that unfavorable environmental factorsplay the important role in etiology and genesis of habitual noncarrying of pregnancy at early stages.

Relative Pitch

Absolute pitch is reported to occur in 1 out of 10,000 persons, usually those trained in music before age 6. We demonstrate that the five individuals we tested, who have Williams syndrome, a condition caused by a microdeletion of about 20 genes in the q11.23 region of one of their two chromosomes number seven, possess near ceiling levels of absolute pitch despite their limited cognitive abilities. With these individuals, we also describe our preliminary findings on relative pitch, transposition, and retention. We discuss the possibilities that (1) the incidence of absolute pitch among individuals with Williams syndrome is higher than that found in the general population and (2) the normal early childhood critical period of absolute pitch acquisition may be extended in individuals with Williams syndrome.

Tritone Paradox

Chapter 5 explores the tritone paradox—a musical illusion that was discovered by the author. Its basic pattern consists of two computer-generated tones that are related by a half-octave (i.e., a tritone). These tones are well defined in pitch class (note name) but ambiguous in pitch height. When one of these tone pairs is played in succession, some people hear an ascending pattern, yet other people hear a descending one. Indeed, a group of people will disagree completely among themselves as to whether such a pair of tones is moving up or down in pitch. Furthermore, any one person hears one of these tone pairs as ascending or descending depending on their note names (such as C–F♯, or G♯–D). How people hear the tritone paradox varies with the geographic location in which they grew up—and so with their native language or dialect. Native English-speaking Californians hear this pattern differently from natives of the south of England. People who are natives of Vietnam hear the pattern quite differently from native English-speaking Californians. The tritone paradox shows, therefore, that the way we perceive music is related to our language, and generally reveals strong effects of our memories and expectations on how we hear music. It also has important implications for absolute pitch (or “perfect pitch”)—the rare ability to name a musical note that is presented in isolation. People make orderly judgments of the tritone paradox, even though they cannot name the notes that they are judging, so they must have an implicit form of absolute pitch.

We have developed an intestinal wound model that includes surgical construction of an ileo-cecal patch to study the complex process of intestinal wound healing. This allows approximation of ileal mucosa to the cecal serosa and facilitates regeneration of ileal mucosa onto the serosal surface of the cecum. The regeneration of ileal mucosa can then be evaluated at different times. The wound model also allows us to determine the rate of intestinal regeneration for a known size of intestinal wound and can be compared in different situations (e.g. with and without EGF and Peyer’s patches).At the light microscopic level it appeared that epithelial cells involved in regeneration of ileal mucosa originated from the enlarged crypts adjacent to the intestinal wound and migrated in an orderly fashion onto the serosal surface of the cecum. The migrating epithelial cells later formed crypts and villi by the process of invagination and evagination respectively. There were also signs of proliferation of smooth muscles underneath the migratory epithelial cells.

The unconditioned GSR’s elicited by tones of 60, 70, 80, and 90 dB SPL were largest in the mouse in the ranges around 10,000 Hz. The growth of response magnitude with intensity followed a power law (10 .17 to 10 .22 , depending upon frequency) and suggested that the unconditioned GSR magnitude assessed overall subjective magnitude of tones to the mouse in an orderly fashion. It is suggested that hearing sensitivity as assessed by these means may be closely related to the spectral content of the mouse’s vocalization as well as to the number of critically sensitive single units in the mouse’s VIIIth nerve.

Background: Orthostatic hypotension (OH) is a disease prevalent among middle-aged men and the elderly. The association between arterial stiffness and OH is unclear. This study evaluates whether arterial stiffness is correlated with OH and tests the usefulness of brachial-ankle pulse wave velocity (baPWV), an arterial stiffness marker, with regard to identifying OH. Patients and methods: A sample of 1,010 participants was recruited from the general population (64.8 ± 7.7 years; 426 men) who attended health check-ups. BaPWV and the radial augmentation index (rAI) were both assessed as the arterial stiffness markers, and OH was determined using blood pressure (BP) measured in the supine position, as well as 30 seconds and 2 minutes after standing. Results: The prevalence of OH in this population was 4.9 %. Compared with the non-OH group, both baPWV (20.5 ± 4.5 vs 17.3 ± 3.7, p < 0.001) and rAI (88.1 ± 10.8 vs 84.2 ± 10.7, p < 0.05) were significantly higher in the OH group. In the multiple logistic regression analysis, baPWV (OR, 1.3; 95 % CI, 1.106–1.528; p < 0.05) remained associated with OH. Moreover, the degree of orthostatic BP reduction was related to arterial stiffness. In addition, increases in arterial stiffness predicted decreases in the degree of heart rate (HR) elevation. Finally, a receiver operating characteristic (ROC) curve analysis showed that baPWV was useful in discriminating OH (AUC, 0.721; p < 0.001), with the cut-off value of 18.58 m/s (sensitivity, 0.714; specificity, 0.686). Conclusions: Arterial stiffness determined via baPWV, rather than rAI, was significantly correlated with the attenuation of the orthostatic hemodynamic response and the resultant OH. The impaired baroreceptor sensitivity might be the mechanism. In addition, baPWV appears to be a relatively sensitive and reliable indicator of OH in routine clinical practice.

Background: Suicidal ideation can often lead to suicide attempts and completed suicide. Studies have shown that Sri Lanka has one of the highest rates of suicide in the world but so far no studies have looked at prevalence of suicidal ideation in a general population in Sri Lanka. Aims: We wanted to determine the prevalence of suicidal ideation by randomly selecting six Divisional Secretariats (Dss) out of 17 in one district. This district is known to have higher than national average rates of suicide. Methods: 808 participants were interviewed using Sinhala versions of GHQ-30 and Beck’s Scale for Suicidal Ideation. Of these, 387 (48%) were males, and 421 (52%) were female. Results: On Beck’s Scale for Suicidal Ideation, 29 individuals (4%) had active suicidal ideation and 23 (3%) had passive suicidal ideation. The active suicidal ideators were young, physically ill and had higher levels of helplessness and hopelessness. Conclusions: The prevalence of suicidal ideation in Sri Lanka is lower than reported from the West and yet suicide rates are higher. Further work must explore cultural and religious factors.
