On neurotransmitter mechanisms of reinforcement and internal inhibition

Experiments reported in this study have been performed in order to investigate cholinergic and GABA-ergic neurotransmitter systems and substance P in the realization of internal inhibition and pain reinforcement. This was accomplished during the elaboration of inhibitory and defensive conditioned reflexes to light flashes in alert, nonimmobilized rabbits. Present results together with a review of past research indicate that the cholinergic system is directly involved in transmitting the effects of pain reinforcement to neocortical neurons. Substance P, a neuropeptide, reduces the background activity of neocortical and hippocampol neurons and the response of cortical neurons to pain and positive conditioned stimuli. The cholinergic system and substance P exert a modulating effect on the elaboration of internal inhibition. Phenybut, a GABA derivative capable of penetrating the blood-brain barrier, enhances inhibitory hyperpolarization in the cerebral cortex and improves discrimination between the inhibitory and reinforcing light flashes. It appears, therefore, that the GABA-ergic system plays a leading part in the elaboration of internal inhibition. Neuronal activity and slow potential changes in response to positive conditioned and pain stimuli occur in the same direction after administering the preparations, and the dynamics of these changes is different from that in responses to inhibitory stimuli. It may be supposed on these grounds that the neurotransmitter and neuromodulator systems studied possess a considerable degree of plasticity.     

The neurophysiological validation of the hyperpolarization theory of internal inhibition

The experiments in conscious non-immobilized rabbits showed that cessation of the reactions without reinforcement (elaboration of the internal inhibition) is accompanied by an enhanced phasic state, by alternation of activation and inhibition of neuron firing, and by the corresponding slow potential oscillation (SPO). These changes can be either localized, predominantly in the structures of conditioned stimulus, or, under enhancement of the inhibitory state, generalized in the brain structures. On the basis of our experience and published data, it is concluded that the above event results from relative enhancement of the inhibitory hyperpolarizing processes due to increase in reactivity of the inhibitory systems to stimulus, which acquires inhibitory properties during learning. Changes in the excitability and reactivity of neuron populations appearing during enhancement of the hyperpolarizing inhibition, and differing in the various brain structures, play an active role in the execution of the main function of the internal inhibition: limitation of excitation transmission to the effectors. An inhibitory mediator gamma aminobutyric acid (GABA) is of great importance in inhibiting the excitation in response to the stimulus which lost its biological significance. These experimental data and their interpretation in the light of published data give the basis for the development of the hyperpolarization theory of internal inhibition.     

Development and validation of a measure of display rule knowledge: the display rule assessment inventory

As one component of emotion regulation, display rules, which reflect the regulation of expressive behavior, have been the topic of many studies. Despite their theoretical and empirical importance, however, to date there is no measure of display rules that assesses a full range of behavioral responses that are theoretically possible when emotion is elicited. This article reports the development of a new measure of display rules that surveys 5 expressive modes: expression, deamplification, amplification, qualification, and masking. Two studies provide evidence for its internal and temporal reliability and for its content, convergent, discriminant, external, and concurrent predictive validity. Additionally, Study 1, involving American, Russian, and Japanese participants, demonstrated predictable cultural differences on each of the expressive modes.     

Wilhelm Reich in Soviet Russia: Psychoanalysis,Marxism, and the Stalinist reaction

Abstract

In 1929, Wilhelm Reich lectured on “Psychoanalysis as a natural science” before the Communist Academy in Moscow; he was the only Freudian-trained Central European psychoanalyst to do so. That same year, his article “Dialectical materialism and psychoanalysis” was published in the Academy's journal, Under the Banner of Marxism, in both Moscow and Berlin. By this time, Reich's involvement with political activism aligned with the Austrian Communist Party was increasing, while simultaneously psychoanalysis in the Soviet Union was in decline. Our paper places these events in their proper historical context and includes a discussion of the various attempts to determine the compatibility of psychoanalysis and Marxism. We offer analyses of both the article, “Dialectical materialism and psychoanalysis,” and the lecture, “Psychoanalysis as a natural science,” and the reactions to both by Reich's Russian critics. We show the ways in which responses to his lecture foreshadow what becomes the standard Soviet assessment of psychoanalysis. As an appendix to this paper, we provide the first English translation of the Russian account of his lecture, as published in the Herald of the Communist Academy.     

Russia's Umma and its Muftis

Abstract

In December 2006, after years of debate, the Romanian parliament passed the country's first postcommunist law on religious freedom and the status of religious denominations. This article offers a detailed examination of the law's provisions, describes the context in which the norm was adopted, discusses the legal framework before the law's passage, and provides a short analysis of the law's reception in Romania.     

Healers,Leaders and Entrepreneurs: Shamanic Revival in Southern Siberia

While it is generally agreed that in the postmodern world all tradition is invented, in many post-colonial contexts the emerging identities are spelled out in the idiom of ‘traditional heritage’. This article considers the social field of ‘shamanism’ as it has been shaped in the post-Soviet years in Tuva, an autonomous republic within the Russian Federation in Southern Siberia, and analyses Tuvan shamanism as a product of local historical and social forces, and global processes. Based on both the ethnography of the organisational structure of contemporary Tuvan shamanism, and portraits of different categories of practitioners, the article analyses continuity and change in various aspects of what is locally seen as ‘traditional knowledge’, and discusses different skills, orientations, and divisions of labour among the practitioners. Shamanism in post-Soviet Siberia is seen as a postmodern religious movement enmeshed in global structures and processes, and it is only in this context that a local tradition can become alive and meaningful again.

Parents' attachment styles,mental representations,and institutionalization of children in Bulgaria

We first summarize the history, extent, and characteristics of institutionalization of non‐orphan children in Bulgaria. Then we describe a study of certain psychological characteristics of mothers who use institutionalization compared with mothers similar in ethnicity and close‐to‐poverty circumstances, those using state daycare programs, and those using weekly care programs for their children. Institutionalizing mothers had been institutionalized themselves far more often than had the other mothers. On two attachment measures, as expected, institutionalizing mothers were less secure and more insecure than daycare mothers, with weekly care mothers intermediate. On a parental representation task, results were somewhat more equivocal. Results suggest that psychological characteristics, especially attachment style, are important in decisions to use institutionalization as a means of child care.     

Electroencephalographic intercentral interaction as a reflection of normal and pathological human brain activity

The authors summarized EEG findings and defined the nature of the intercentral EEG relationships in different functional states in healthy subjects and patients with organic cerebral pathology, based on a coherence analysis. Similar EEG characteristics in healthy individuals were identified: an anterior-posterior gradient of average coherence levels, the type of cortical-subcortical relationships in anterior cerebral structures. Right- and left-handed individuals showed frequent and regional differences in EEG coherence, which mainly reflected specificity of intracortical relationships. Development and regression of pathology in right-and left-handed individuals with organic brain lesions were thought to be caused by these differences. Lesions of regulatory structures (diencephalic, brain stem and limbic structures) provoked a more diffused kind of changes of intercentral relationships, in contrast to cortical pathology. These changes tended to reciprocate. The dynamic nature of intercentral relationships and their interhemispheric differences was revealed when changing functional states of the brain (increase and decrease of functional level) in healthy individuals and patients with organic cerebral pathology in the process of conscious and psychic activity restoration. Changing activity predominance of certain regulatory structures was considered one of the most important factors determining the dynamic nature of EEG coherence.     

Neuronal manifestation of two-way connections in conditioning

Neuronal characteristics of two-way conditional connections were studied in chronic experiments with alert cats during different types of alimentary conditional reflexes. Single unit and multi-unit activities were chronically recorded in the visual and motor cortex and the lateral hypothalamic nucleus. Cross-correlational analysis of neuronal impulse trains was used to characterize the organization of neuron groups in brain structures involved in the formation of a conditional reflex. The experimental data showed an increase in the number of neuronal two-way connections after learning in all three investigated coordinations: visual-motor, visual-hypothalamic, and motor-hypothalamic. With visual-motor interneuronal coordination, the strengthening of two-way connections was due to the enhancement of connections from the motor to the visual neuron (backward connections); with visual- and motor-hypothalamic coordination, the number of interneuronal connections was equal in both directions. In all investigated coordinations, the analysis of the temporal parameters of the interactions between the neurons of different groups showed a dependence of the conditioning procedure on delays of up to 30 ms and a dependence of the motivational state on the interval range of 90–100 ms. The polyfunctional and polycomponent character of two-way neuronal connections in conditioning can be inferred from these data. Evaluation of the activity of neurons of different brain structures suggests the specific organization of intracortical and cortical-subcortical integrity in learning.
