  2. 6. Actuators for autonomous microrobots

    Author : Niklas Snis; Stefan Johansson; Urban Simu; Alvo Aabloo; Uppsala universitet; []
    Keywords : Engineering physics; Locomotion; Microrobot; PZT; P VDF-TrFE ; Autonomous; Multilayer; Actuator; Teknisk fysik;

    Abstract : This thesis presents actuators used in autonomous microsystems. Characteristic for all actuators presented is the low drive voltage and the low power consumption. Different motion mechanisms have been studied and applied in various locomotion modules for microrobots. READ MORE

  4. 7. Crossing the Midline : Locomotor Neuronal Circuitry Formation

    Author : Fatima Memic; Klas Kullander; Avihu Klar; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CPG; CIN; neuronal network; locomotion; left-right alternation;

    Abstract : Networks at various levels of the nervous system coordinate different motor patterns such as respiration, eye or hand movements and locomotion. Intrinsic rhythm-generating networks that are located in the spinal cord generate motor behaviors that underlie locomotion in vertebrates. READ MORE

  5. 8. Deciphering the Locomotor Network : The Role of Spinal Cord Interneurons

    Author : Sharn Perry; Klas Kullander; Kimberly Dougherty; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Locomotion; central pattern generator; mouse; gait; recurrent inhibition; Renshaw cell; Dmrt3; Chrna2; Neuroscience; Neurovetenskap;

    Abstract : In the spinal cord, an intricate neural network generates and coordinates the patterning of limb movements during locomotion. This network, known as the locomotor central pattern generator (CPG), comprises of various cell populations that together orchestrate the output of motor neurons. READ MORE

  6. 9. Effects of mixtures of endocrine disrupting chemicals – Thyroid disruption and behavioural effects in fish models

    Author : Lina Birgersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; endocrine disrupting chemicals; ecotoxicology; zebrafish; perch; locomotion; behaviour; thyroid disruption; EDC mixtures;

    Abstract : Wildlife and humans are continuously exposed to thousands of man-made compounds, including chemicals that are able to act as endocrine disruptors (EDCs). These pollutants are able to affect vital processes including brain development, reproduction, metabolism and growth. READ MORE

  7. 10. Diving into the zebrafish locomotor network : A study on dI6 interneurons

    Author : Ana Belen Iglesias Gonzalez; Henrik Boije; Filippo Del Bene; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; danio rerio; locomotion; dmrt3a; wt1a; calretinin; transcriptome; spinal cord; morphology; dI6 neurons; knock-down out; Neuroscience; Neurovetenskap;

    Abstract : The generation and coordination of locomotion comprise of inhibitory and excitatory interneurons that govern motor neuron output to muscles. This neuronal network is known as the central pattern generator (CPG). Spinal inhibitory interneurons that originate from the dI6 population play a crucial role in the coordination of locomotor output. READ MORE
