Humans, brains, and their environment: marriage between neuroscience and anthropology?

The Cognitive-Emotional Design and Study of Architectural Space: A Scoping Review of Neuroarchitecture and Its Precursor Approaches

Humans respond cognitively and emotionally to the built environment. The modern possibility of recording the neural activity of subjects during exposure to environmental situations, using neuroscientific techniques and virtual reality, provides a promising framework for future design and studies of the built environment. The discipline derived is termed "neuroarchitecture". Given neuroarchitecture's transdisciplinary nature, it progresses needs to be reviewed in a contextualised way, together with its precursor approaches. The present article presents a scoping review, which maps out the broad areas on which the new discipline is based. The limitations, controversies, benefits, impact on the professional sectors involved, and potential of neuroarchitecture and its precursors' approaches are critically addressed.

The New Age of Adolescence and the Use of Social Networks in Youths

Prof. Massimo Ammaniti is considered one of the most eminent Italian psychoanalysts specialized in the area of human development. In addition to carrying out his activity as a university lecturer and carrying out his profession as a psychoanalyst, Massimo Ammaniti is also the author of more than 200 scientific publications. He is a member of the International Psychoanalytical Association and he is in the Board of the World Association of Infant Mental Health. His main interests focus on parents-children interactions, adolescence, neurobiology, and the changes in the family functioning in the modern society. In this interview, he shares his thoughts about the recent transformations in the developmental stage of adolescence and reflects on the use made by youths of today’s social networks.

Self-relevance modulates brain responses to angry body expressions

In a social context, the direction of the body of surrounding agents indicates whether one is the potential target of an impending action or simply an observer, and thus influences the way one processes and reacts to their emotional expressions. The present functional magnetic resonance imaging experiment investigated how self-relevance influences anger processing in the brain by independently manipulating target (oriented to self or to other) and emotion (neutral and anger). The perception of body expression of anger elicits activity in a previously identified network that includes the amygdala, the fusiform gyrus, the superior temporal sulcus and the premotor cortex. Activity within this network is independent of body direction and is parametrically modulated by the intensity of the bodily emotional expression. Moreover, the ventromedial prefrontal cortex and somatosensory cortices responded preferentially to anger expressions oriented to self. We suggest that these brain areas may participate in the selection of specific behavioural strategies when one is the potential target of someone's anger.

Tractographic analysis of historical lesion surgery for depression

Various surgical brain ablation procedures for the treatment of refractory depression were developed in the twentieth century. Most notably, key target sites were (i) the anterior cingulum, (ii) the anterior limb of the internal capsule, and (iii) the subcaudate white matter, which were regarded as effective targets. Long-term symptom remissions were better following lesions of the anterior internal capsule and subcaudate white matter than of the cingulum. It is possible that the observed clinical improvements of these various surgical procedures may reflect shared influences on presently unspecified brain affect-regulating networks. Such possibilities can now be analyzed using modern brain connectivity procedures such as diffusion tensor imaging (DTI) tractography. We determined whether the shared connectivities of the above lesion sites in healthy volunteers might explain the therapeutic effects of the various surgical approaches. Accordingly, modestly sized historical lesions, especially of the anatomical overlap areas, were 'implanted' in brain-MRI scans of 53 healthy subjects. These were entered as seed regions for probabilistic DTI connectivity reconstructions. We analyzed for the shared connectivities of bilateral anterior capsulotomy, anterior cingulotomy, subcaudate tractotomy, and stereotactic limbic leucotomy (a combination of the last two lesion sites). Shared connectivities between the four surgical approaches mapped onto the most mediobasal aspects of bilateral frontal lobe fibers, including the forceps minor and the anterior thalamic radiations that contacted subgenual cingulate regions. Anatomically, convergence of these shared connectivities may derive from the superolateral branch of the medial forebrain bundle (MFB), a structure that connects these frontal areas to the origin of the mesolimbic dopaminergic 'reward' system in the midbrain ventral tegmental area. Thus, all four surgical anti-depressant approaches may be promoting positive affect by converging influences onto the MFB.
