1. 1. Functional Imaging of Spinal Locomotor Networks

   Författare :Chetan Nagaraja; Klas Kullander; Gilad Silberberg; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Central pattern generators; two-photon microscopy; locomotor rhythm; multiple rhythmicities; inhibitory neurotransmission; Neuroscience; Neurovetenskap;

   Sammanfattning : Movement is necessary for the survival of most animals. The spinal cord contains neuronal networks that are capable of motor coordination and of producing different movements. In particular, a very reduced neuronal network in the spinal cord can produce simple rhythmic outputs even in the absence of descending or sensory inputs. LÄS MER

3. 2. Crossing the Midline : Locomotor Neuronal Circuitry Formation

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

   Sammanfattning : 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. LÄS MER

4. 3. A behavioural investigation into Eristalis tenax : Pursuit, approach estimation, locomotor activity and rearing

   Författare :Malin Thyselius; Karin Nordström; Anna Rostedt Punga; Yuri Ogawa; Emily Baird; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Eristalis tenax; Insect rearing; Hoverflies; Pollinators; Circadian rhythm; Target detection; Motion vision; Pursuit; LAMS; Flight arena;

   Sammanfattning : Hoverflies are suggested to be the 2nd most important pollinator group after bees and bumblebees, and with the changing climate and dwindling numbers of pollinators it might never have been more important understanding our pollinators. Given the hoverflies’ small brains, beautiful aerial acrobatics, good temporal resolution, but limited spatial resolution, these flies make interesting study animals for flight behaviour and vision research.

5. 4. Mechanisms of rhythm generation in the lamprey locomotor network

   Författare :Lorenzo Cangiano; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Animals propel themselves through space, swimming, walking or flying, by rhythmic oscillatory movements of their body and limbs. In vertebrates these movements are mainly generated by specialized neuronal circuits in the spinal cord, called central pattern generators (CPGs) for locomotion. LÄS MER

7. 5. Circadian Rhythms in Moth Sex Pheromone Communication

   Författare :Germund von Wowern; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physiology of invertebrates; växtparasitologi; Entomologi; plant parasitology; Entomology; Ecology; Ekologi; locomotor activity; social synchronisation; PDH; corazonin; PBAN; pheromone response; sex phermone; Lepidoptera; Ryggradslösa djurs fysiologi; calling behaviour; circadian rhythm;

   Sammanfattning : Sex pheromone communication and related physiological processes are regulated by circadian clock mechanisms in many moth species. This thesis includes studies of circadian rhythms in sexually relevant behaviours and communication in the Egyptian cotton leafworm Spodoptera littoralis, the turnip moth Agrotis segetum, the Indian meal moth Plodia interpunctella and the Mediterranean flour moth Ephestia kuehniella.
