  text: Animals rely on compensatory actions to maintain stability and navigate their
    environment efficiently. These actions depend on global visual motion cues known
    as optic-flow. While the optomotor response has been the traditional focus for
    studying optic-flow compensation in insects, its simplicity has been insufficient
    to determine the role of the intricate optic-flow processing network involved
    in visual course control. Here, we reveal a series of course control behaviours
    in Drosophila and link them to specific neural circuits. We show that bilateral
    electrical coupling of optic-flow-sensitive neurons in the fly’s lobula plate
    are required for a proper course control. This electrical interaction works alongside
    chemical synapses within the HS-H2 network to control the dynamics and direction
    of turning behaviours. Our findings reveal how insects use bilateral motion cues
    for navigation, assigning a new functional significance to the HS-H2 network and
    suggesting a previously unknown role for gap junctions in non-linear operations.

  text: "During navigation, animals can infer the structure of the environment by
    computing the optic flow cues elicited by their own movements, and subsequently
    use this information to instruct proper locomotor actions. These computations
    require a panoramic assessment of the visual environment in order to disambiguate
    similar sensory experiences that may require distinct behavioral responses. The
    estimation of the global motion patterns is therefore essential for successful
    navigation. Yet, our understanding of the algorithms and implementations that
    enable coherent panoramic visual perception remains scarce. Here I pursue this
    problem by dissecting the functional aspects of interneuronal communication in
    the lobula plate tangential cell network in Drosophila melanogaster. The results
    presented in the thesis demonstrate that the basis for effective interpretation
    of the optic flow in this circuit are stereotyped synaptic connections that mediate
    the formation of distinct subnetworks, each extracting a particular pattern of
    global motion. \r\nFirstly, I show that gap junctions are essential for a correct
    interpretation of binocular motion cues by horizontal motion-sensitive cells.
    HS cells form electrical synapses with contralateral H2 neurons that are involved
    in detecting yaw rotation and translation. I developed an FlpStop-mediated mutant
    of a gap junction protein ShakB that disrupts these electrical synapses. While
    the loss of electrical synapses does not affect the tuning of the direction selectivity
    in HS neurons, it severely alters their sensitivity to horizontal motion in the
    contralateral side. These physiological changes result in an inappropriate integration
    of binocular motion cues in walking animals. While wild-type flies form a binocular
    perception of visual motion by non-linear integration of monocular optic flow
    cues, the mutant flies sum the monocular inputs linearly. These results indicate
    that rather than averaging signals in neighboring neurons, gap-junctions operate
    in conjunction with chemical synapses to mediate complex non-linear optic flow
    computations.\r\nSecondly, I show that stochastic manipulation of neuronal activity
    in the lobula plate tangential cell network is a powerful approach to study the
    neuronal implementation of optic flow-based navigation in flies. Tangential neurons
    form multiple subnetworks, each mediating course-stabilizing response to a particular
    global pattern of visual motion. Application of genetic mosaic techniques can
    provide sparse optogenetic activation of HS cells in numerous combinations. These
    distinct combinations of activated neurons drive an array of distinct behavioral
    responses, providing important insights into how visuomotor transformation is
    performed in the lobula plate tangential cell network. This approach can be complemented
    by stochastic silencing of tangential neurons, enabling direct assessment of the
    functional role of individual tangential neurons in the processing of specific
    visual motion patterns.\r\n\tTaken together, the findings presented in this thesis
    suggest that establishing specific activity patterns of tangential cells via stereotyped
    synaptic connectivity is a key to efficient optic flow-based navigation in Drosophila
    melanogaster."

  text: "Background: Biases of DNA repair can shape the nucleotide landscape of genomes
    at evolutionary timescales. The molecular mechanisms of those biases are still
    poorly understood because it is difficult to isolate the contributions of DNA
    repair from those of DNA damage.\r\n\r\nResults: Here, we develop a genome-wide
    assay whereby the same DNA lesion is repaired in different genomic contexts. We
    insert thousands of barcoded transposons carrying a reporter of DNA mismatch repair
    in the genome of mouse embryonic stem cells. Upon inducing a double-strand break
    between tandem repeats, a mismatch is generated if the break is repaired through
    single-strand annealing. The resolution of the mismatch showed a 60–80% bias in
    favor of the strand with the longest 3′ flap. The location of the lesion in the
    genome and the type of mismatch had little influence on the bias. Instead, we
    observe a complete reversal of the bias when the longest 3′ flap is moved to the
    opposite strand by changing the position of the double-strand break in the reporter.\r\n\r\nConclusions:
    These results suggest that the processing of the double-strand break has a major
    influence on the repair of mismatches during single-strand annealing."

  text: Characterizing the fitness landscape, a representation of fitness for a large
    set of genotypes, is key to understanding how genetic information is interpreted
    to create functional organisms. Here we determined the evolutionarily-relevant
    segment of the fitness landscape of His3, a gene coding for an enzyme in the histidine
    synthesis pathway, focusing on combinations of amino acid states found at orthologous
    sites of extant species. Just 15% of amino acids found in yeast His3 orthologues
    were always neutral while the impact on fitness of the remaining 85% depended
    on the genetic background. Furthermore, at 67% of sites, amino acid replacements
    were under sign epistasis, having both strongly positive and negative effect in
    different genetic backgrounds. 46% of sites were under reciprocal sign epistasis.
    The fitness impact of amino acid replacements was influenced by only a few genetic
    backgrounds but involved interaction of multiple sites, shaping a rugged fitness
    landscape in which many of the shortest paths between highly fit genotypes are
    inaccessible.
