Structural Analyses in the Study of Anxiety and Anxiety-Related Behaviour
2016
According to the latest Diagnostic and Statistical Manual of Mental Disorders, 5th edition, anxiety encompasses various conditions sharing an excessive sense of fear and/or apprehension for no evident reason and related behavioural disturbances (Association, 2013). The association of such a gloomy symptomatology, with the great diffusion in the general population, explains the critical impact of anxiety disorders on inter-personal relationships and job-related activities (Greenberg et al.,1999; Wittchen & Hoyer, 2001; Keeley & Storch, 2009). Hence, anxiety disorders represent an important and consistent topic of discussion, not only in terms of underlying neuro-psychological processes but, …
Brain histamine depletion enhances motor sequences complexity of mice tested in open field: new insights from temporal pattern analysis
2016
Background: Tourette Syndrome (TS) has been classically related to dopaminergic dysregulation of Basal Ganglia circuitry [1]. However, the identification of a rare autosomal dominant form of TS, linked to a mutation of the key-enzyme for Histamine (HA)1 synthesis (l-Histidine decarboxylase, Hdc), has shed light on a putative involvement of this monoamine on the pathophysiology of tic and related disorders and fostered the development of coherent animal models [2]. Although HA-deficient rodents display markedly increased tic-like stereotypies following amphetamine administration, neither underlying nor predisposing differences in the open field test have been reported in quantitative measure…

Discovery of recurring behavioural sequences in Wistar rat social activity: Possible support to studies on Autism Spectrum Disorders.
2017
This study was undertaken to investigate whether, in rat interactive activities, recurring sequences of behavioural events might be identified and how and to what extent each component of the pair is involved. To this aim, the multivariate temporal-pattern (t-pattern) analysis was applied to the social interactions of 9 pairs of male Wistar rats tested in open field. Interactive activities were classified into intra- and inter-subjects. Quantitative evaluations showed that intra-subject behavioural elements represented 62.37% and inter-subject ones 37.63% of the comprehensive behaviour. T-pattern analysis revealed the presence of 221 different t-patterns organized in four different categori…

Discovering Hidden Temporal Patterns in Behavior and Interaction
2016
Discovering hidden recurring patterns in observable behavioral processes is an important issue frequently faced by numerous advanced students and researchers across many research areas, such as, for example, psychology, biology, sports, robotics, media, fi nance, and medicine. As generally, the many powerful methods included in statistical software packages were not developed for this kind of analysis, discovering such patterns has proven a particularly diffi cult task, due to a lack of (a) adequate formalized models of the kinds of patterns to look for, (b) corresponding detection algorithms, and (c) their implementation in available software. The research described in this book is based o…

Structural analyses in the study of behavior : From rodents to non-human primates

Ajuts: J-BL's research was funded by Natural Sciences and Engineering Research Council of Canada (NSERC, Discovery Grant #: 2015-06034 to J-BL). MC, SA, and GC's research was funded by a grant from the University of Palermo, Italy. The term " structure " indicates a set of components that, in relation to each other, shape an organic complex. Such a complex takes on essential connotations of functionally unitary entity resulting from the mutual relationships of its constituent elements. In a broader sense, we can use the word " structure " to define the set of relationships among the elements of an emergent system that is not determined by the mere algebraic sum of these elements, but by the…
