Suppression of extinction with TMS in humans: from healthy controls to patients.

2006

We review a series of studies exemplifying some applications of single-pulse and paired-transcranial magnetic stimulation (TMS) in the study of spatial attention and of its deficits. We will focus primarily on sensory extinction, the failure to consciously perceive a contralesional sensory stimulus only during bilateral stimulation of homologous surfaces. TMS studies in healthy controls show that it is possible either to interfere or modulate the excitability of the parietal cortex during sensory (i.e. tactile and visual) attentional tasks, thus reproducing a condition of virtual extinction. TMS studies in patients with unilateral (mainly right) brain damage show that the modulation of the …

Machinery Failure Approach and Spectral Analysis to Study the Reaction Time Dynamics over Consecutive Visual Stimuli: An Entropy-Based Model.

2020

[EN] The reaction times of individuals over consecutive visual stimuli have been studied using an entropy-based model and a failure machinery approach. The used tools include the fast Fourier transform and a spectral entropy analysis. The results indicate that the reaction times produced by the independently responding individuals to visual stimuli appear to be correlated. The spectral analysis and the entropy of the spectrum yield that there are features of similarity in the response times of each participant and among them. Furthermore, the analysis of the mistakes made by the participants during the reaction time experiments concluded that they follow a behavior which is consistent with …

Classroom application of using visual stimuli in learning dynamics and pitch

2014

Listening is a common activity in music lessons. It is difficult for teachers to know whether students are learning by listening. In this study, visual stimuli include imagery, metaphor, and symbols, were introduced to students in the experimental group to learn dynamics and pitch. A control group received the same lessons without any visual stimuli. Both groups received the same tests, pre-test and post-test, after the two lessons. Tests were divided into two parts including choosing the correct dynamic changes and distinguishing higher or lower pitch for the melody. Results showed the experimental group had improved more than the control group. The change of the experimental group in rela…

Szkoła - w stronę wielozmysłowego i wielointeligentnego poznawania świata

2019

Artykuł dotyczy teorii inteligencji wielorakich a także kompetencji zawodowych współczesnego nauczyciela jest interdyscyplinarnym ujęciem zagadnienia z pogranicza - : psychologii, neurobiologii – a umiejscowionych kontekstach współczesnej pedagogiki. Teoria o istnieniu wielu niezależnych od siebie inteligencji Howarda Gardnera kwestionująca traktowanie inteligencji jako „jednolitej konstrukcji” jest bazą wyjściową do deliberacji nad osobniczymi predylekcjami sensorycznymi ucznia. Zdobyta wiedza takiej proweniencji pozwala nauczycielowi na bardziej kreatywną interakcje edukacją i wychowawczą z uczniem

Drosophila adult and larval pheromones modulate larval food choice

2014

Insects use chemosensory cues to feed and mate. In Drosophila , the effect of pheromones has been extensively investigated in adults, but rarely in larvae. The colonization of natural food sources by Drosophila buzzatii and Drosophila simulans species may depend on species-specific chemical cues left in the food by larvae and adults. We identified such chemicals in both species and measured their influence on larval food preference and puparation behaviour. We also tested compounds that varied between these species: (i) two larval volatile compounds: hydroxy-3-butanone-2 and phenol (predominant in D. simulans and D. buzzatii , respectively), and (ii) adult cuticular hydrocarbons (CHs).

Synthetic/ECM-inspired hybrid platform for hollow microcarriers with ROS-triggered nanoporation hallmarks

2017

Reactive oxygen species (ROS) are key pathological signals expressed in inflammatory diseases such as cancer, ischemic conditions and atherosclerosis. An ideal drug delivery system should not only be responsive to these signals but also should not elicit an unfavourable host response. This study presents an innovative platform for drug delivery where a natural/synthetic composite system composed of collagen type I and a synthesized polythioether, ensures a dual stimuli-responsive behaviour. Collagen type I is an extracellular matrix constituent protein, responsive to matrix metalloproteinases (MMP) cleavage per se. Polythioethers are stable synthetic polymers characterized by the presence o…
