41	Hippocampal-Temporopolar Connectivity Contributes to Episodic Simulation During Social Cognition Pehrs, Corinna, Zaki, Jamil, Taruffi, Liila, Kuchinke, Lars, Koelsch, Stefan 28 September 2018 (has links) People are better able to empathize with others when they are given information concerning the context driving that person’s experiences. This suggests that people draw on prior memories when empathizing, but the mechanisms underlying this connection remain largely unexplored. The present study investigates how variations in episodic information shape the emotional response towards a movie character. Episodic information is either absent or provided by a written context preceding empathic film clips. It was shown that sad context information increases empathic concern for a movie character. This was tracked by neural activity in the temporal pole (TP) and anterior hippocampus (aHP). Dynamic causal modeling with Bayesian Model Selection has shown that context changes the effective connectivity from left aHP to the right TP. The same crossed-hemispheric coupling was found during rest, when people are left to their own thoughts. We conclude that (i) that the integration of episodic memory also supports the specific case of integrating context into empathic judgments, (ii) the right TP supports emotion processing by integrating episodic memory into empathic inferences, and (iii) lateral integration is a key process for episodic simulation during rest and during task. We propose that a disruption of the mechanism may underlie empathy deficits in clinical conditions, such as autism spectrum disorder. info:eu-repo/classification/ddc/520 ddc:520
42	<b>Development of a Variable Dilution Olfaction Chamber Coupled with a Proton Transfer Reaction Mass Spectrometer for Evaluation of Human Response to Indoor Emissions from Scented Volatile Chemical Products</b> Jordan N Cross (16700061) 02 August 2023 (has links) <p>This study is focused on the design, production, and operation of a controlled environmental olfaction chamber to evaluate human physiological and emotional response to volatile chemical emissions (VCPs) from scented household products in addition to careful characterization of the volatile organic compounds (VOCs) present in these product emissions. Utilizing proton transfer reaction time-of-flight mass spectrometry, the chamber can collect VCP emissions and identify VOCs present to complete an accurate chemical profile of household and common product emissions not previously known. This instrument is one of the first of its kind and will serve as a key element in understanding the relationship between human physical and cognitive health and the built environment.</p> Architectural engineering Air pollution modelling and control Health and ecological risk assessment volatile organic componds volatile chemical products air pollution environmental chamber proton transfer reaction mass spectrophotometry personal care products (PCPs) VOCs human response psychophysiology. physiological response built environment indoor air pollution indoor air quality olfaction odor response emotional response particulate matter product emission testing chambers product emission instrument developement psychophysiological response odor assessment odor and emotional assessment human wellbeing cognitive function
