Abstract:

Repeated exposure to psychostimulant drugs induces numerous behavioral, and neuronal changes, which in animals is thought to model certain neural adaptations that may contribute to drug addiction. Chronic AMPH has repeatedly been shown to alter the acquisition and expression of associations between a conditioned stimulus (CS) and natural rewards. Although repeated psychostimulant exposure can interfere with associative learning about natural food rewards, the manner in which these treatments affect acquisition and expression of these associations remains unclear. The current study investigated

Abstract:

Little research has been done on antonymic relations, a great deal of this has been done by linguists Paradis et al. Gamification was used in natural language acquisition by Bos and Nissim in their 2015 study about noun-noun compound relations, but gamification of information retrieval remains a relatively new field of study. This thesis reproduced work done by Paradis et al. in an attempt to answer the following questions for Swedish antonyms: will reversing word order in antonymic relations affect the strength of said word pair? Will the perceived strength of canonical antonyms have a lower

Abstract:

In the last decade, (non)prescription opioid abuse, opioid use disorder (OUD) diagnoses, and opioid-related overdoses have risen and represent a significant public health concern. One method of understanding OUD is as a disorder of choice that requires choosing opioid rewards at the expense of other nondrug rewards. The characterization of OUD as a disorder of choice is important as it implicates decision- making processes as therapeutic targets, such as the valuation of opioid rewards. However, reward-value measurement and interpretation are traditionally different in substance abuse research

Abstract:

Gli endocannabinoidi giocano un ruolo fondamentale nella regolazione della trasmissione sinaptica. L’esposizione ad eventi stressanti o gratificanti induce modificazioni sinaptiche nelle diverse aree cerebrali. L’attività del sistema degli endocannabinoidi nei circuiti neuronali coinvolti nelle risposte allo stress e alla gratificazione (reward) suggerisce il suo coinvolgimento nelle risposte comportamentali e negli adattamenti a livello sinaptico tipiche dello stress, delle droghe d’abuso ed altre forme di comportamenti reward dipendenti.

Abstract:

Le tabagisme, qui concerne un milliard de personnes à travers le monde, est à l’origine de plus de 8 millions de décès évitables par an, et constitue ainsi un enjeu sanitaire majeur. La nicotine, principal composé actif du tabac, agit au niveau du système nerveux en se liant aux récepteurs nicotiniques de l’acétylcholine (nAChR). Cette liaison produit de manière concomitante des effets récompensants et aversifs, permettant respectivement de promouvoir et limiter la consommation de tabac. Les nAChR sont exprimés au niveau du système de la récompense, notamment l’aire tegmentale ventrale (VTA),

Abstract:

Nicotinic acetylcholine receptors (nAChR) are neurotransmitter-gated ion channels that exist as a family of subtypes defined by unique subunit compositions. nAChR containing α6 subunits (α6*-nAChR) have attracted interest because α6 subunits are thought to be localized in brain regions implicated in reward, mood and drug dependence. To provide new information necessary toward a more complete understanding of roles of α6*-nAChR in neuropsychiatric health and disease, three lines of investigation were pursued. A set of stably transfected, human, immortalized cell lines were generated that hetero

Abstract:

In the field of neuroscience, being in love and feeling romantically attached to a partner is described as a dynamic process. Romantic love may be viewed as a motivational system, changing throughout time and place, fluctuating on the interest and motivation of the individual. Early memories and attachment towards a caregiver, lay the foundation for later attachment behavior, also known as attachment styles. In this thesis, an exploratory approach is present. The thesis aims to introduce and describe the neural correlates of romantic love and romantic attachment. Brain regions concerned with r

Les récepteurs cannabinoides CB1 contrôlent les propriétés renforçantes de la nicotine. Par conséquent, nous avons examiné le rôle des récepteurs CB1 du BNST. Nous montrons que l'acquisition de l’AAIV de nicotine est associée à une facilitation persistante de l'induction d’une potentialisation à long t

Research Doctorate - Doctor of Philosophy (PhD)<br>The lateral hypothalamus (LH) is anatomically positioned to receive and send an array of afferent and efferent signals within the brain. This is important as distinct behaviours relating to homeostasis are coordinated and executed by LH cells and signalling pathways. The LH can control appetitive behaviour as well as motivation and reward-seeking, as well as being sensitive to stress signals. Importantly, the LH has a heterogenous composition, comprising of many diverse cell types. The functional importance of these intra-LH populations is inc

Empirical analysis combines results of Bayesian Model Averaging and logistic regression. Results reveal that firstly, language style of project descriptions does not possess any significant predictive power. Secondly, that utilization of a video, size of pledging goal,

Abstract:

The human visual system is remarkable for the variety of functions it can be used for and the range of conditions under which it can perform, from the detection of small brightness changes to guiding actions in complex movements. The human eye is foveated and humans continually make eye and body movements to acquire new visual information. The mechanisms that control this acquisition and the associated sequencing of eye movements in natural circumstances are not well understood. While the visual system has highly parallel inputs, the fovea must be moved in a serial fashion. A decision proce

Cocaine has been known to block reuptake of these neurotransmitters by inhibiting their own transporters, thus enhance synaptic availability of these neurotransmitters. Increased synaptic monoamine concentration have been associated with the euphoric (reinforcing) efficacy and the priming effects of cocaine in reinstatement designs. In this study, the acquisition curve of cocaine self administration was examined in MAO subtype B knockout

During the 1740’s, Hudson Bay went from an obscure backwater of the British Empire to a locus of colonial ambition. Arthur Dobbs revitalized Northwest Passage exploration, generating new information about the region’s environment and indigenous peoples. This study explores evolving English and British representations of Hudson Bay’s climate and landscape in travel and natural history writing, and probes British anxieties about foreign environments. I demonstrate how Dobbs’ ideology of improvement optimistically re-imagined the North, opening a new discursive space wherein the Subarctic could b
