Social interactions are fundamental for human behavior, but the quantification of their neural underpinnings remains challenging. Here, we used hyperscanning functional MRI (fMRI) to study information flow between brains of human dyads during real-time social interaction in a joint attention paradigm. In a hardware setup enabling immersive audiovisual interaction of subjects in linked fMRI scanners, we characterize cross-brain connectivity components that are unique to interacting individuals, identifying information flow between the sender’s and receiver’s temporoparietal junction. We replicate these findings in an independent sample and validate our methods by demonstrating that cross-brain connectivity relates to a key real-world measure of social behavior. Together, our findings support a central role of human-specific cortical areas in the brain dynamics of dyadic interactions and provide an approach for the noninvasive examination of the neural basis of healthy and disturbed human social behavior with minimal a priori assumptions.

The current digest touches upon the negative effect of institutionalization on child development and the role of early family care in the formation of attachment, prevention of psychopathology and developing the connections between the brain and social behavior (based on the studies of Romanian orphans).

Personality Features

The paper presents the results of a study of relationships between personality features and reactions to frustration among the student-actors. We tested the hypothesis about the correlation between behaviors in situations of frustration and such personal characteristics as empathy, trust, and reflexivity in relation to social behavior. Sample: 142 first-year students of a Moscow theatre college. Methods: R. Cattell’s 16 PF Questionnaire and S. Rosenzweig’s frustration picture test. Results: it is shown that projective emotional sensitivity is associated with two types of reactions — self-defense through aggression and self-defense through the acceptance of guilt. Conclusions: we revealed the important role of reactions aimed at resolving the frustrating situation through appealing to the interaction partner; this mode of behavior in a conflict situation is associated with a set of personal characteristics corresponding to the Groundedness factor in Cattell’s test, which implies attention to the specific circumstances of the action.

Nucleus Cuneatus

Although neuroaxonal dystrophy (NAD) has been examined by light and electron microscopy for years, the nature of the components in the dystrophic axons is not well understood. The present report examines nucleus gracilis and cuneatus (the dorsal column nuclei) in the brain stem of aging mice.Mice (C57BL/6J) were sacrificed by aldehyde perfusion at ages ranging from 3 months to 23 months. Several brain areas and parts of other organs were processed for electron microscopy.At 3 months of age, very little evidence of NAD can be discerned by light microscopy. At the EM level, a few axons are found to contain dystrophic material. By 23 months of age, the entire nucleus gracilis is filled with dystrophic axons. Much less NAD is seen in nucleus cuneatus by comparison. The most recurrent pattern of NAD is an enlarged profile, in the center of which is a mass of reticulated material (reticulated portion; or RP).

SummaryBlood was injected into the brains of dogs to produce artificial haematomas, and paraffin injected to produce intracerebral paraffin masses. Cerebrospinal fluid (CSF) and peripheral blood samples were withdrawn at regular intervals and their fibrinolytic activities estimated by the fibrin plate method. Trans-form aminomethylcyclohexane-carboxylic acid (t-AMCHA) was administered to some individuals. Genera] relationships were found between changes in CSF fibrinolytic activity, area of tissue damage and survival time. t-AMCHA was clearly beneficial to those animals given a programme of administration. Tissue activator was extracted from the brain tissue after death or sacrifice for haematoma examination. The possible role of tissue activator in relation to haematoma development, and clinical implications of the results, are discussed.
