Making a mountain out of a molehill: on the role of the rostral dorsal anterior cingulate and dorsomedial prefrontal cortex in conscious threat appra…
2013
According to appraisal theories fear and anxiety are elicited by the subjective evaluation of a situation or internal state as threatening. From this perspective anxiety disorders result from maladaptive, exaggerated threat appraisals that over-estimate the threatening consequences of often innocuous stimuli and situations. When these threat over-estimations occur at the level of conscious processing, they are referred to as catastrophizing and worrying. Both are major pathogenic processes in many clinical theories of anxiety. Until recently, little has been known about the neurobiological basis of normal and pathological conscious threat appraisal. Here, we review functional neuroimaging s…
Neurohybrid Memristive CMOS-Integrated Systems for Biosensors and Neuroprosthetics
2020
Here we provide a perspective concept of neurohybrid memristive chip based on the combination of living neural networks cultivated in microfluidic/microelectrode system, metal-oxide memristive devices or arrays integrated with mixed-signal CMOS layer to control the analog memristive circuits, process the decoded information, and arrange a feedback stimulation of biological culture as parts of a bidirectional neurointerface. Our main focus is on the state-of-the-art approaches for cultivation and spatial ordering of the network of dissociated hippocampal neuron cells, fabrication of a large-scale cross-bar array of memristive devices tailored using device engineering, resistive state program…
Synaptic connectivity of the cholinergic axons in the olfactory bulb of the cynomolgus monkey.
2015
The olfactory bulb (OB) of mammals receives cholinergic afferents from the horizontal limb of the diagonal band of Broca (HDB). At present, the synaptic connectivity of the cholinergic axons on the circuits of the OB has only been investigated in the rat. In this report, we analyze the synaptic connectivity of the cholinergic axons in the OB of the cynomolgus monkey (Macaca fascicularis). Our aim is to investigate whether the cholinergic innervation of the bulbar circuits is phylogenetically conserved between macrosmatic and microsmatic mammals. Our results demonstrate that the cholinergic axons form synaptic contacts on interneurons. In the glomerular layer, their main targets are the peri…
The moderating role of personality in the relationship between temporal perspectives and facebook addiction
2020
In the present paper, we tested the hypothesis that neuroticism moderates the relationship between past-negative or present-fatalistic temporal perspectives and Facebook addiction. A sample of 233 Facebook users (Female: 66%, mean age: 21.4 years) filled self-reports measures of temporal perspective, personality traits, and Facebook Addiction. Results at two moderation models showed that only past-negative significantly predicts Facebook addiction through neuroticism's moderation effect. Individuals with a negative temporal orientation to the past, who are also characterized by a high neuroticism level, were more addicted to Facebook. Peculiar associations between past-negative temporal per…
Characterization of neutrophil subsets in healthy human pregnancies
2014
We have previously shown that in successful pregnancies increased arginase activity is a mechanism that contributes to the suppression of the maternal immune system. We identified the main type of arginase-expressing cells as a population of activated low-density granulocytes (LDGs) in peripheral blood mononuclear cells and in term placentae. In the present study, we analyzed the phenotype of LDGs and compared it to the phenotype of normal density granulocytes (NDGs) in maternal peripheral blood, placental biopsies and cord blood. Our data reveal that only LDGs but no NDGs could be detected in placental biopsies. Phenotypically, NDGs and LDGs from both maternal and cord blood expressed diff…
Designing Classroom Practices for Teaching Online Inquiry : Experiences from the Field
2021
Students face several challenges when asked to locate relevant and credible information from the internet. This article introduces three principles for designing online inquiry lessons and documents what we learned from five language arts teachers from Finland who implemented and provided feedback on a learning unit framed in those design principles. Teachers implemented a researcher-designed online inquiry unit in nine upper secondary school classrooms. The unit included four 75-minute lessons sequenced to support the location, evaluation, and synthesis of information students encountered in an online inquiry task. Teachers’ diaries revealed their impressions of the unit, problems encounte…
Dignity and existential concerns among nursing homes residents from the perspective of their relatives
2014
Aims and objectives: The aim of this cross-country Scandinavian study was to explore how residents in nursing homes experience that their dignity is promoted and attended to. This is one part of the Scandinavian project in which we interviewed residents, relatives and staff members. Background: The main subject concerns the dignity of residents of nursing homes for older people. This article brings forward results from interviews of relatives on how they experience that the dignity is met, promoted and attended to for their next of kin. Design: The study was qualitative with a hermeneutic approach. Methods: Qualitative research interviews of 28 relatives of residents at six participating nu…
Understanding the influence of context in technology integration from teacher educators’ perspective
2021
The perspective of teachers is important for advancing the use of technology in classrooms. A considerable number of research studies have explained context in ways that have narrowed the understanding of its impact on successful technology integration. This study employs the Technological Pedagogical and Content Knowledge (TPACK) model as a lens in understanding factors influencing teachers’ integration of technology in classrooms. Data were collected using focused interviews of 19 teacher educators of three colleges of education from the southern part of Nigeria. The results reveal that among the level contexts, the meso level presented the most challenges to teachers’ efforts at integrat…
¿Un transhumanismo nietzscheano? Sobre la parcialidad del alegato
2020
espanolEl articulo analiza desde una perspectiva critica las tentativas de interpretar a Nietzsche como un precursor del transhumanismo. Tras una breve contextualizacion del fecundo debate en torno a Nietzsche y el transhumanismo, se evalua el caracter fraccional o parcial del alegato de Stefan Sorgner en favor de un “transhumanismo nietzscheano”. Despues, se investiga la tension entre humanidad, la superacion del ser humano y su cria en los escritos de Nietzsche. Una vez ejecutado este analisis, y sin animo de caer en el anacronismo, se sostiene que Nietzsche anticipa ciertamente un germen de la idea de post-humanidad, en su critica de la cultura humanista y en su invitacion a transformar …
Saying-Doing Correspondence
2002
The study of the correspondence concerns the functional relationships between an individual’s verbal and non-verbal behavior. The analysis of the functional relations between saying and doing is interesting from a theoretical perspective (e.g.: how and when do they relate together? Learning to tell the truth etc.) and from an applied point of view: many clinical procedures, as verbal forms of psychotherapy, are based on the idea that changing people’s verbalizations about their behavior will lead to corresponding changes in the way they behave. Since say-do correspondence training has been employed in a variety of behaviors and types of procedures to examine the conditions upon which the ar…
