2. 6. Context dependent adaptation of biting behavior in human

   Author : Anders Johansson; Benoni Edin; Karl-Gunnar Westberg; Peter Svensson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EMG; bite force; human; mastication; muscles; jaw opening reflex; motor control; reflex modulation; periodontal attachment loss; periodontitis; fysiologi; Physiology;

   Abstract : The focus of this thesis was to study an action that humans perform regularly, namely, to hold a morsel between the teeth and split it into smaller pieces. Three different issues related to this biting behavior were addressed:  (1) the effect of redu­c­ed perio­dontal tissues on food holding and splitting behavior; (2) the behavioral conse­quences of performing different bite tasks with different functional requirements, i.

4. 7. Imaging imagining actions

   Author : CJ Olsson; Lars Nyberg; A.Mark Williams; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mental training; motor training; novices; imaging; athletes; fMRI; internal imagery; motor representation; brain systems; practice; learning; transfer; active; Physiology; Fysiologi;

   Abstract : Mental training has been studied extensively for the past century but we are still not completely sure how it affects brain and behavior. The aim of this doctoral thesis was to examine one aspect of mental training i.e. motor imagery. READ MORE

5. 8. Dopamine and the affective-cognitive gradient in the human striatum studied with multimodal brain imaging

   Author : Filip Grill; Anna Rieckmann; Lars Nyberg; Alison Adcock; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dopamine; striatum; incentive; motor; associative; reinforcement learning; reward prediction error; positron emission tomography; functional magnetic resonance imaging; PET MR; cognitive modelling;

   Abstract : Both dopamine and the dopamine rich brain area, striatum, have been linked to behaviors related to incentives, motor action, and associative processing. Most of the cortex sends projections to the striatum, these connections have been described as a gradient organization representing a repertoire of functional behaviors. READ MORE

6. 9. The Biological Importance of the Amino Acid Transporter SLC38A10 : Characterization of a Knockout Mouse

   Author : Frida A. Lindberg; Robert Fredriksson; Erika Roman; Karin Nordenankar; Vootele Vöikar; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Solute carrier; SLC; SNAT10; SLC38A10; phenotyping; behavior; amino acids; knockout mouse model; Farmaceutisk vetenskap; Pharmaceutical Science;

   Abstract : The biggest group of transporters, the solute carriers (SLCs), has more than 400 members, and about 30% of these are still orphan. In order to decipher their biological function and possible role in disease, there is a need for characterization of these. READ MORE

7. 10. Development and Characterisation of a Rat Model of Parkinson's Disease

   Author : Matilde Negrini; Beteendevetenskapligt laboratorium; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson s disease PD ; behavior; gene therapy; rat model; dopamine; alpha-synuclein; AAV Adeno-Associated virus ; PFFs;

   Abstract : Preclinical rodent models of Parkinson’s Disease (PD) based on alpha-synuclein (αSyn) present some of the pathological hallmarks of the human condition, such as the progressive loss of dopaminergic neurons in the substantia nigra (SN) and the development of behavioural deficits. However, numerous reports on these models highlighted the variable outcomes that might originate from them if not validated properly. READ MORE
