Discrimination des expressions faciales et environnement olfactif – Corrélats cérébraux en électroencéphalographie (EEG) chez l’adulte et le très jeu…
2019
This thesis examines the mechanisms subtending the perception of emotional facial expressions and their early development using a Fast Periodic Visual Presentation (FPVS) approach coupled with electroencephalography (EEG). More specifically, we tried to characterize brain responses reflecting facial expression discrimination and to determine whether hedonic odor contexts influence these responses in adults (studies 1 and 2), and in infants at different developmental stages (studies 3 and 4).We showed specific responses to the discrimination of every facial expression in the adult brain, indicating rapid and automatic categorization of basic facial expressions (study 1). In addition, we reve…
The role of the thalamus in amnesia: a tractography, high-resolution MRI and neuropsychological study.
2008
Although it is well established that thalamic lesions may lead to profound amnesia, the precise contribution of thalamic sub-regions to memory remains unclear. In an influential article Aggleton and Brown proposed that recognition memory depends on two processes supported by distinct thalamic and cortical structures. Familiarity is mediated by the mediodorsal (MD) thalamic nucleus and the entorhinal/ perirhinal cortex. Recollection ismediated by the anterior thalamic nucleus (AN), the mamillothalamic tract (MTT) and the hippocampus. The authors also suggested that the lateral dorsal nucleus (LD) may contribute to the thalamic/hippocampus system, thereby implying that the LD may play a role …

Vācu romantisma filozofijas programmas ietekme uz F.Dostojevska darbiem
2015
Maģistra darba tēma ir „Vācu romantisma filozofijas programmas ietekme uz F.Dostojevska darbiem”. Romantisms pēc sava tematiskā satura un ietekmes ir tikpat nozīmīgs kā tā priekšgājēji – renesanse, klasicisms un apgaismība. Romantisms ir sniedzis iespēju cilvēkam sevi uzlūkot kā bezgalīgi dievišķo būtni, kamēr apgaismības ietvaros, cilvēks ir bijis ierobežots racionālisma ietvaros. Romantisma idejas un tā redzējums uz cilvēku un to pasauli ir aktuāls arī mūsdienu pētniecībā. Romantisms ir bijis tāds strāvojums, kas savulaik ir ietekmējis 19.gs. Eiropas izcilākos filozofus un rakstniekus tālu aiz vācu zemju robežām. Krievu filozofiski orientētais domātājs Fjodors Dostojevskis ir bijis viens …
Evidence of regional differences in chlorine perception by consumers: sensitivity differences or habituation?
2014
Chlorinous flavors are a leading cause of customers9 dissatisfaction with drinking water. Potential differences in chlorine perception were investigated by conducting sensory testing experiments in France and Spain to assess consumers9 sensory sensitivity (chlorine flavor detection threshold and supra-threshold intensity) as well as their liking of and acceptability for chlorinated solutions. In both countries, two groups of panelists were constituted based on their water drinking habits (tap vs. bottled water). Chlorine flavor detection threshold was found to vary depending on countries (0.17 mg/L Cl 2 in France and 0.56 mg/L Cl 2 in Spain). Taking into account that mean flavor detection t…

Indivīda brīvības problemātika Dostojevska romānā "Velni" un Kamī lugā "Velni"
2018
Bakalaura darbā tiek apskatīta eksistenciālās filosofijas izpratne un problemātika par indivīda brīvību Dostojevska romānā “Velni” un Kamī lugā “Velni”. Tuvāk tiks aplūkota Dostojevska romāna noformējuma nozīme, brīvības negatīvā puse, idejas, kas pakļauj indivīdu un nihilistiskais tēlu skatījums uz dzīvi. Darba mērķis ir izpētīt abu autoru uzskatus par indivīdu un tā brīvību, un skatīt to problemātiskos aspektus caur tēliem darbos “Velni”. Lai sasniegtu mērķi, tiek izvirzīti trīs uzdevumi. Pirmkārt, Dostojevska un Kamī tekstu izpēte, lai iepazītos ar darbu pamatproblēmām. Otrkārt, sekundārās literatūras analizēšana, lai izprastu, kā tiek interpretēta abu autoru filosofiskā doma. Treškārt, …

Mammary odor cues and pheromones: mammalian infant-directed communication about maternal state, mammae, and milk
2010
International audience; Neonatal mammals are exposed to an outstandingly powerful selective pressure at birth, and any mean to alleviate their localization effort and accelerate acceptance to orally grasp a nipple and ingest milk should have had advantageous consequences over evolutionary time. Thus, it is essential for females to display a biological interface structure that is sensorily conspicuous and executively easy for their newborns. Females' strategy to increase the conspicuousness of nipples could only exploit the newborns' most advanced and conserved sensory systems, touch and olfaction, and selection has accordingly shaped tactilely and olfactorily conspicuous mammary structures.…
Food memory and its relation with age and liking: An incidental learning experiment with children, young and elderly people
2008
International audience; The present study compared incidental learning and food memory in children, young adults and elderly people for three sensory modalities (taste, texture and aroma). The relation of gender and liker-status (i.e. how much we like a product) with food memory was also investigated. Participants received a complete meal including a custard dessert used as target under incidental learning conditions. 24 h later, participants were confronted with a series of samples consisting of the target and slightly modified versions of the target (distractors) and were unexpectedly asked to perform an ‘‘absolute memory’’ (‘‘Did you eat this sample yesterday?’’) and a ‘‘relative memory’…
