  1. 1. Investigation of Injury Predictors for Rat Neuro Trauma

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Rosetta Maglio; [2024]
    Keywords : Finite element method; Rat brain traumatic brain injury; Rat brain finite element model; Strain; Strain rate; Product of strain and strain rate; Rotational direction; Rotational duration; Injury prediction; Finita elementmetoden; Råtthjärnans finita elementmodell; Belastning; Belastningshastighet; Produkten av belastning och belastningshastighet; Rotationsriktning; Rotationstid; Skadeförutsägelse;

    Abstract : A traumatic brain injury is usually caused by a direct impact to the head and is a common cause of disability and death all around the world. The most effective method to predict brain injury today, is to use a finite element head model. READ MORE

  3. 2. How does different fresh gas flows affect stress in rats during anaesthesia induction with sevoflurane in a chamber?

    University essay from SLU/Dept. of Clinical Sciences

    Author : Linda Klevestedt; [2023]
    Keywords : råtta; beteende; stress; anestesi; inhalationskammare; excitation; induktion; uppvakning; färskgasflöde; sevofluran;

    Abstract : The rat is one of the most used laboratory animals in Europe today. When replacement of live animals in research is not feasible, the aim is to improve the welfare of those animals by reducing stress and suffering. READ MORE

  4. 3. Localisation of Traumatic Brain Injury

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Yogesh Sharma; MIchael Zewde Hägglund; [2023]
    Keywords : Traumatic Brain Injury TBI ; Rat brain; Finite Element Method FEM ; strain; localisation; thalamus; hypothalamus; neocortex; Traumatisk hjärnskada TBI ; Råtthjärna; Finita Element Metod FEM ; belastning; lokalisering; thalamus; hypotalamus; neocortex;

    Abstract : TBI stands for Traumatic Brain Injury and refers to damage to the brain resulting from an external physical force, such as a blow, jolt, or penetrating injury to the head. Common causes of TBI include falls, motor vehicle accidents, sports injuries, and violence and has been linked to thousands of deaths and injuries in the US and the EU alike. READ MORE

  5. 4. Acclimatisation of rats before scientific experiments

    University essay from SLU/Dept. of Clinical Sciences

    Author : Viktoria Brånsgård; [2023]
    Keywords : acclimatisation; acclimatisation period; rat; transportation; stress; corticosterone;

    Abstract : The most common laboratory animals in Sweden today are mice, rats, and zebrafish. We sent out an anonymous digital survey to investigate if scientific facilities in Sweden acclimatise their rats after transportation, how long the acclimatisation time is, and how the acclimatisation is conducted.

  6. 5. EVOKED PHASE COHERENCE AS A BIOMARKER FOR ADAPTIVE NEUROMODULATION IN RAT MODEL OF PARKINSON'S DISEASE

    University essay from Umeå universitet/Institutionen för psykologi

    Author : Love Zackrisson; [2023]
    Keywords : Adaptive; Closed Loop; Neuromodulation; Parkinson’s Disease; Rat model; 6-OHDA; ITC; Phase Coherence; Bayesian Model; Classifier; Spinal Cord Stimulation; Deep Brain Stimulation.; Adaptiv; Closed Loop; Neuromodulation; Parkinson’s Sjukdom; Råttmodell; 6-OHDA; ITC; Faskoherens; Bayesiansk Modell; Klassificerare; Ryggradsstimulering; Djup Hjärnstimulering.;

    Abstract : Neuromodulation, such as spinal cord stimulation (SCS) and deep brain stimulation (DBS), has been shown to modulate pathophysiological brain activity and provide symptomatic therapy for several neurological disorders, including Parkinson’s Disease. The effectiveness of this therapy could likely be further improved by neuromodulation that is adaptive, delivering stimulation more selectively, by monitoring a biomarker in recorded brain signals, which indicates the presence of a pathological state.
