  1. 11. Bio-inspired crossover and a model of neuronal reprogramming

    Författare :Adriaan Merlevede; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; evolutionary comuptation; crossover; genetic recombination; permutation; flexible genome; direct neuronal reprogramming;

    Sammanfattning : Bio-inspired crossover:Natural genomes are affected by various kinds of mutations, manifesting as variations in the genome. This includes modifications to individual base pairs (single nucleotide polymorphism, SNP), but also short insertions and deletions (indels), and variations in the position (translocations) or multiplicity (copy number variations) of genetic sequences.

  3. 12. Large-scale simulation of neuronal systems

    Författare :Mikael Djurfeldt; Örjan Ekeberg; Charles Peck; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : Biologically detailed computational models of large-scale neuronal networks have now become feasible due to the development of increasingly powerful massively parallel supercomputers. We report here about the methodology involved in simulation of very large neuronal networks. LÄS MER

  4. 13. Diving into the zebrafish locomotor network : A study on dI6 interneurons

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

    Sammanfattning : 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. LÄS MER

  5. 14. Neuronal mechanisms of feedback postural control

    Författare :Li-Ju Hsu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :postural control; equilibrium; body configuration; reticulospinal neurons; stretch receptor neurons; galvanic vestibular stimulation; artificial feedback; locomotion; spinalization; rabbit; lamprey;

    Sammanfattning : Different species maintain a basic body posture due to the activity of the postural control system. An efficient control of the body orientation, as well as the body configuration, is important for standing and during locomotion. LÄS MER

  7. 15. Modulation of cellular mechanisms in a spinal locomotor network

    Författare :Jesper Tegnér; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Neuronal Network; Calcium Channels; Calcium-DependentPotassium Channels; Neuronal Oscillator; Neuromodulation; GABAg receptors; Lamprey; Locomotion; Spinal Cord; Computer Simulation;

    Sammanfattning : Neuronal networks generate behaviour. Thus, to understand behaviour requires information on how neuronal networks work in terms of their cellular components. The overall aim of this work has been to link processes occurring at an ionic level to the operation of a neural network specialized for undulatory locomotion. LÄS MER
