Differential electrodermal and phasic heart rate responses to personally relevant information: Comparing sleep and wakefulness

2010

This study examined autonomic physiological responses to personally relevant information presented during sleep and wakefulness. Heart rate and electrodermal reactions to subjects’ own first name and other first names were measured during sleep stage 2, rapid eye movement (REM) sleep, and wakefulness. Across all conditions, larger skin conductance responses were elicited by subjects’ own first name. During REM sleep, personally relevant information led to larger heart rate acceleration, whereas an enhanced deceleration was examined during wakefulness. These findings suggest that auditory information is processed on a semantic level even during sleep. However, personally relevant information…

Flow field, swimming velocity and boundary layer: parameters which affect the stimulus for the lateral line organ in blind fish

1988

The data presented support the hypothesis that the flow field supplies the stimulus to the lateral line organ (LLO) in blind cave fish (Anoptichthys jordani). Two basic predictions from the theoretical analysis of the flow field were confirmed: (i) individual blind cave fish prefer particular swimming velocities, (ii) the velocity preferred depends on the cross-sectional area (CSA) of the fish, i.e. the smaller the CSA the higher the swimming velocity. This relationship was found also in experimentally blinded fish of other species. Furthermore, when placed in unfamiliar surroundings, blind cave fish swim at higher velocities than in familiar surroundings for a certain habituation period. T…

Relations between basal ganglia and hippocampus: Action of substantia nigra and pallidum

1986

Several interrelationships exist between basal ganglia and hippocampus. The ventral striatum appears to be involved in the control of the dopaminergic nigro-striatal pathway. The caudate, in turn, seems to influence the hippocampal theta rhythm and to inhibit hippocampal spikes. In the present work the role played by globus pallidus pars interna and substantia nigra pars compacta on hippocampal bioelectrical activity is studied. Injection of sodium penicillin i.v. produces steady interictal spikes in the hippocampus. Substantia nigra stimulation induces regular theta rhythm and inhibits the spikes. Pallidal stimulation, on the contrary, appears to strongly enhance epileptiform activity, pro…

Moderate-Vigorous Physical Activity across Body Mass Index in Females : Moderating Effect of Endocannabinoids and Temperament

2014

Altres ajuts: This manuscript was supported by grants from Instituto Salud Carlos III (FIS PI11/210 and CIBERobn). Sarah Sauchelli is recipient of a pre-doctoral Grant (2013-17) by IDIBELL. Jose C. Fernández-García is recipient of a 'Rio Hortega' contract from 'Instituto de Salud Carlos III', Madrid, Spain (CM12/00059). The funders had no role in the study design, data collection and analysis, decision to publish, or preparation of the manuscript. Endocannabinoids and temperament traits have been linked to both physical activity and body mass index (BMI) however no study has explored how these factors interact in females. The aims of this cross-sectional study were to 1) examine differences…

The bulbar respiratory centre in the rabbit. I. Changes of respiratory parameters caused by intermittent electrical bulbar stimulation during inspira…

1976

In anesthetized rabbits, spirogram and diaphragmatic activity were examined during electrical stimulation of the bulbar lateral reticular formation. The activity of bulbar respiratory neurons was recorded contra-or ipsilaterally to the stimulation site. One volley of repetitive stimuli per breath was delivered during either inspiration or expiration. 1. Each volley of about 120 ms duration at 100 pulses per second, delivered early ininspiration, caused an immediate and transient inhibition of the diaphragmatic activity. An inspiratory, rebound comprising lengthening of inspiration and increase in tidal volume occurred. a) “Inspiratory” and “expiratory-inspiratory” phase-spanning neurons exh…

Superresolved imaging of remote moving targets.

2006

We present a superresolving approach that allows one to exceed the diffraction limit and recover highly resolved contours of moving targets from a sequence of low-resolution images. The presented approach is suitable for remote sensing applications. The resolution decoding algorithm that is used to recover the high-resolution features of the target can be run partially via optical means and that way can be used to reduce the required computational complexity.

Research of organic agricultural production support in Poland

2017

The features of supporting organic production in Poland are analyzed in the article. Poland is characterized by the largest employment of the population and the number of farms in the organic sector among the countries of Europe. Despite the favorable natural and climatic conditions, the scientific and practical base, significant areas occupied by organic production, the powerful export potential of the country, the proportion of organic operators in the structure of agricultural producers is very low. The main obstacles to the transition to organic principles are the poor development of environmental infrastructure and support from various services of the entire agricultural system. Theref…

Exploring Collective Action Dynamics in Online Communities from a Critical Realist Perspective

2016

Scholars have been increasingly studying Online Communities (OCs) for a variety of purposes, focusing on issues like individual motivation, knowledge sharing, and governance structure. Few studies focused on the entanglement among technology, people, and organizational structures that support working dynamics within OCs. This paper addresses this issue by exploring causal mechanisms sustaining the collective actions of OCs through a retroduction process. Based on the study of the OC of an Italian political movement, the Five Star Movement, the concept of affordance is involved to describe the generative mechanisms and new affordances are identified on collective action within OCs. Our work …

From protest to parliament : The role of digital technologies within an online community

2020

Our teaching case introduces the story of how the Italian Five Star Movement used digital technologies in the growth from a personal blog discussing politics back in 2005 to the most voted party in the Italian election in 2018, becoming part of the government. The Italian Five Star Movement is among the largest eParticipation initiatives globally. It is (almost) totally organized through the use of digital platforms. Members form online communities and are continuously invited to discuss and make decisions that end up into Italian politics. Adopting a chronological perspective, we describe the development of the Italian Five Star Movement, focusing on their use of digital technologies at va…
