Anhedoni, minskad motivation att uppleva lust, är associerad med förändringar i belöningssystemet. Belägen i ventrala striatum utgör den bilaterala nucleus accumbens (NAcc) den centrala noden i detta nätverk, där dopamin agerar som huvudsaklig excitatorisk neurotransmitter. Studier med funktionell magnetresonanstomografi (fMRI) har visat att aktiviteten i ventrala striatum minskar under belöningsbAnhedonia, reduced motivation to experience pleasure, is associated with alterations in the circuitry of the reward system. Located in the ventral striatum, the bilateral nucleus accumbens (NAcc) is the central hub of this network where dopamine acts as the main excitatory neurotransmitter. Studies using functional magnetic resonance imaging (fMRI) found that activity in the ventral striatum is de

Objective: Data remain divergent regarding the activational effects of endogenous hormones on adult cognitive function. We examined the association between cognition, hormones and androgen receptor (AR) CAG repeat length in a large cohort of men. Design: Community-based, cross-sectional study of 3369 men aged 40-79 years. Methods: Cognition tests were the Rey-Osterrieth Complex Figure, Camden Topo

We report magnetic properties and relative paleointensity (RPI) proxies from a suite of 10 conventional piston cores and Kasten cores from the SW Iberian Margin collected during cruise JC089 of the RSS James Cook in August 2013. Mean sedimentation rates are in the 10–20 cm/kyr range. Age models were acquired by correlation of Ca/Ti and Zr/Sr XRF core-scanning data to L* reflectance from the Cariac

In this review, we analyze several types of graphene-based sensors for glucose detection with respect to their preparation, properties and efficiency in electro-chemical processes. Graphene may display different types of defects, which play a role in the electron transfer processes. Oxygenated groups on the edges of graphene planes reduce the graphene in-plane conductivity, but may enhance the het

Permutational Grammar, PG, is a grammar inspired by the Free Word Order grammar, FOG, presented in Vladimir Pericliev & Alexander Grigorov 1992. Some languages, notably Latin, are said to have free word order, see e.g. Siewierska 1988. The name Permutational Grammar is derived from the use of permutations in order to generate order variation. The general problem to be solved by FOG and PG is t

Free space optics is an interesting alternative for telemetry with medical implants, due to the high data bandwidths available at optical frequencies. Especially implanted brain-computer interfaces gives rise to large data sets that needs to be transmitted transcutaneous. In this paper we show that it is possible to establish such a link at near-IR wavelengths using a modulated reflector in the im

Superconducting devices, based on the Cooper pairing of electrons, play an important role in existing and emergent technologies, ranging from radiation detectors1,2 to quantum computers3. Their performance is limited by spurious quasiparticle excitations formed from broken Cooper pairs4–12. Efforts to achieve ultra-low quasiparticle densities have reached time-averaged numbers of excitations on th

Denna kandidatuppsats är en kvalitativ undersökning över hur länder i en rykteskris använder nationsvarumärkning och mjuk makt för att motverka negativa stereoty- per och förbättra sitt globala rykte. Nationsvarumärkning beskrivs som ett strate- giskt verktyg för att förbättra ett lands rykte och attraktivitet genom olika mark- nadsförings- och varumärkesmetoder. Flerstegsmodellen introduceras som
