This study sets out to investigate the mechanisms by which psychoanalytical psychotherapy can induce neurobiological changes. From Neuroscience which, in accordance with his thinking at the time, Freud never disregarded, the concepts of neuronal plasticity, enriched environment and the neurobiological aspects of the attachment process. From Psychoanalysis, the theory of transference, M. Mahler’s psychological evolution model, the concept of the regulating function of the self-objects and Winnicott’s holding environment concept. Together these provide a useful bridge toward the understanding of the neurobiological changes resulting from psychoanalytical psychotherapy. One concludes that psychoanalytical psychotherapy, through transference, acts as a new model of object relation and learning which furthers the development of certain brain areas, specifically, the right hemisphere, and the prefrontal and limbic cortices, which have a regulating function on affects.

The modalities of communication are the sum of the expression dimension (linguistics) and the expressivity dimension (prosody), both being equally important in language communication. The expressivity dimension which comes first in the act of speech, is the basis on which phonemes, syllables, words, grammar and morphosyntax, i.e., the expression dimension of speech is superimposed. We will review evidence (1) revealing the importance of prosody in language acquisition and (2) showing that prosody triggers the involvement of specific brain areas dedicated to sentences and word-list processing. To support the first point, we will not only rely on experimental psychology studies conducted in newborns and young children but also on neuroimaging studies that have helped to validate these behavioral experiments. Then, neuroimaging data on adults will allow for concluding that the expressivity dimension of speech modulates both the right hemisphere prosodic areas and the left hemisphere network in charge of the expression dimension

Processing Network

Human kin recognition activates substrates of the extended facial processing network, notably the right-hemisphere structures involved in self-face recognition and posterior medial cortical substrates. To understand the mechanisms underlying prosociality toward kin faces in comparison to other familiar faces, we investigated the neural correlates of implicit trustworthiness ratings to faces of actual kin and personal friends, controlling for activation to distracter faces. When controlling for activation associated with unknown faces, trustworthiness ratings of faces of kin, compared to friends, were associated with increased activation in the dorsal anterior cingulate cortex, posterior cingulate, and precuneous. On the other hand, trustworthiness ratings of friend faces, relative to kin faces, were associated with the lateral occipital gyrus and insular cortex. Trustworthiness ratings for unknown faces were only associated with activation in the fusiform gyrus. These findings suggest that we should employ medial cortical substrates known to be part of the self-other network when making implicit social judgements about kin, but not other classes of facial stimuli.

Pain is defined as “an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage”. This complex perception arises from the coordinated activity of several brain areas processing either sensory–discriminative or affective–motivational components. Functional studies performed in healthy volunteers revealed that affective–emotional components of pain are processed bilaterally but present a clear lateralization towards the right hemisphere, regardless of the site of stimulation. Studies at the cellular level performed in experimental animal models of pain have shown that neuronal activity in the right amygdala is clearly pronociceptive, whilst activation of neurons in the left amygdala might even exert antinociceptive effects. A shift in lateralization becomes evident during the development of chronic pain; thus, in patients with neuropathic pain symptoms, there is increased activity in ipsilateral brain areas related with pain. These observations extend the asymmetrical left–right lateralization within the nervous system and provide a new hypothesis for the pathophysiology of chronic forms of pain. In this article, we will review experimental data from preclinical and human studies on functional lateralization in the brain during pain processing, which will help to explain the affective disorders associated with persistent, chronic pain.

Aspects of Northoff's argument lend themselves to the ongoing investigation of localizing the self in the brain. Recent data from the fields of neuropsychology and cognitive neuroscience provide evidence that the right hemisphere is a candidate for localization of self. The data on catatonia further that proposition and add insight into the continuing investigation of self in the brain across sensory and motor domains.

Integrated global power from the primary structures that composed the Default Mode Network (DMN) and from a random collection of other structures were measured by sLORETA (standardized low-resolution electromagnetic tomography) for young university volunteers who had completed an inventory that contained a subscale by which egocentricity has been inferred. Subjects who exhibited higher scores for egocentricity displayed significantly more power within the DMN structures relative to comparison areas. This was not observed for individuals whose egocentricity scores were lowest where the power differences between the DMN and comparison structures were not significant statistically. DMN power was greater in the right hemisphere than the left for men but greater in the left hemisphere than the right for women. The results are consistent with our operating metaphor that elevation of power or activity within the DMN is associated with greater affiliation with the self and its cognitive contents.

Recent large-scale neuroimaging studies suggest that most parts of the human brain show structural differences between the left and the right hemisphere. Such structural hemispheric asymmetries have been reported for both cortical and subcortical structures. Interestingly, many neurodevelopmental and psychiatric disorders have been associated with altered functional hemispheric asymmetries. However, findings concerning the relation between structural hemispheric asymmetries and disorders have largely been inconsistent, both within specific disorders as well as between disorders. In the present review, we compare structural asymmetries from a clinical neuroscience perspective across different disorders. We focus especially on recent large-scale neuroimaging studies, to concentrate on replicable effects. With the notable exception of major depressive disorder, all reviewed disorders were associated with distinct patterns of alterations in structural hemispheric asymmetries. While autism spectrum disorder was associated with altered structural hemispheric asymmetries in a broader range of brain areas, most other disorders were linked to more specific alterations in brain areas related to cognitive functions that have been associated with the symptomology of these disorders. The implications of these findings are highlighted in the context of transdiagnostic approaches to psychopathology.

ABSTRACTBackgroundDespite claims that lesional mania is associated with right-hemisphere lesions, supporting evidence is scarce, and association with specific brain areas has not been demonstrated.AimsTo test whether focal brain lesions in lesional mania are more often right-than left-sided, and if lesions converge on areas relevant to mood regulation.MethodsWe performed a systematic literature search (PROSPERO registration CRD42016053675) on PubMed and Web-Of-Science, using terms that reflected diagnoses and structures of interest, and lesional mechanisms. Two researchers reviewed the articles separately according to PRISMA Guidelines, to select reports of adult-onset hypomania, mania or mixed state following a focal brain lesion. When available, eligible lesion images were manually traced onto the corresponding slices of MNI space, and lesion topography analyzed using standard brain atlases. Pooled-analyses of individual patient data were performed.ResultsData from 207 lesional mania patients was extracted from 110 reports. Among patients with focal lesions (N=197) more patients had lesions involving the right (84.3%) than the left (34.5%) hemisphere. Among 54 lesion images that were available, right-sided predominance of lesions was confirmed, and found to be was conserved across multiple brain regions, including the temporal lobe, fusiform gyrus and thalamus. These, in addition to several frontal lobe areas, were also identified as preferential lesion sites in comparisons with control lesions.ConclusionsPooled-analyses, based on the most comprehensive dataset of lesional mania available to date, confirm a preferential association with right-hemisphere lesions, while suggesting that several brain areas/circuits, relevant to mood regulation, are most frequently affected.

The “feeling of a presence” is the distinct awareness of the physical presence of somebody in the near extracorporeal space. Although fairly frequently confined to one side of the body, systematic documentation of the lateralization of the phenomenon has not yet been attempted. A brief tabular summary of 11 cases of the unilateral feeling of a presence in association with focal brain pathology (seven left-hemisphere lesions, four right-hemisphere lesions) shows lateralization to the left in five, to the right in six cases. The data, together with the scattered reports of unilaterally felt presences in patients with nonfocal brain pathology and in healthy individuals, do not support claims that the left hemispace is the preferred location. Any models of hemispheric specialization in the sense of self which are derived from observations of felt presences remain speculative. Nevertheless, clinicians are encouraged to document carefully all the unilateral aspects of the feeling of a presence as well as of other reduplicative phenomena involving the self.

Perception Of Biological Motion

These experiments use functional magnetic resonance imaging (fMRI) to reveal neural activity uniquely associated with perception of biological motion. We isolated brain areas activated during the viewing of point-light figures, then compared those areas to regions known to be involved in coherent-motion perception and kinetic-boundary perception. Coherent motion activated a region matching previous reports of human MT/MST complex located on the temporo-parieto-occipital junction. Kinetic boundaries activated a region posterior and adjacent to human MT previously identified as the kinetic-occipital (KO) region or the lateral-occipital (LO) complex. The pattern of activation during viewing of biological motion was located within a small region on the ventral bank of the occipital extent of the superior-temporal sulcus (STS). This region is located lateral and anterior to human MT/MST, and anterior to KO. Among our observers, we localized this region more frequently in the right hemisphere than in the left. This was true regardless of whether the point-light figures were presented in the right or left hemifield. A small region in the medial cerebellum was also active when observers viewed biological-motion sequences. Consistent with earlier neuroimaging and single-unit studies, this pattern of results points to the existence of neural mechanisms specialized for analysis of the kinematics defining biological motion.

The aim of this study was to apply frequency bands to explore how mental rotation strategies affect the identification of 2D figures. Eighteen adults were recruited for this study. In the ERP experiments, the participants were required to identify 2D figures with mental rotation. The results showed the differences between the high-achieving (HA) and low-achieving (LA) spatial ability participants in their use of mental rotation for identifying 2D figures. At 300-380 ms, the HA participants showed higher brain activity in the right hemisphere than in other brain areas, whereas the LA participants showed activity in the whole brain. At 520 to 620 ms, the areas of brain activity were in the opposite hemisphere for the HA and LA participants. The highest brain activity was shown in the left hemisphere of the HA participants and in the right hemisphere for the LA participants at 520 to 620 ms. The implication of this study is that right hemisphere specialization for mental rotation might appear in early cognitive processing, but in late cognitive processing, the left hemisphere specialization form of mental rotation might show an advantage.
