  1. 1. Feedback control of cerebellar learning

    Författare :Anders Rasmussen; Associativ inlärning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Motor learning; Rescorla-Wagner; Anticipation; In vivo Electrophysiology; Purkinje cells; Nucleo-Olivary inhibition; Inferior Olive; Classical Conditioning; Eyeblink Conditioning; Feedback;

    Sammanfattning : The ability to anticipate future events and to modify erroneous anticipatory actions is crucial for the survival of any organism. Both theoretical and empirical lines of evidence implicate the cerebellum in this ability. It is often suggested that the cerebellum acquires “expectations” or “internal models”. LÄS MER

  3. 2. Social Policy in Development Contexts : Drivers, Mechanisms and Outcomes

    Författare :Sebastian Sirén; Kenneth Nelson; Ann-Zofie Duvander; Olof Bäckman; Björn Halleröd; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; social policy; social protection; political economy; welfare state; comparative politics; causal mechanisms; development; poverty; inequality; inclusive growth; partisan politics; sustainable development goals; global studies; Sociology; sociologi;

    Sammanfattning : Economic growth amidst staggering inequality in many low- and middle-income countries makes the quest to end global poverty more topical than ever. Calls to leave no one behind in the course of development underscore the need to reconsider the role of policy frameworks in emerging economies. LÄS MER

  4. 3. 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

  5. 4. Antibody Feedback Regulation : From Epitope Masking to T Helper Cell Activation

    Författare :Andrew Getahun; Birgitta Heyman; Hans-Gustaf Ljunggren; Daniel Conrad; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immunology; Immune regulation; B cells; T cells; Antibodies; Fc Receptors; Antigen presentation; Transgenic Knockout Mice; Immunologi; Immunology; Immunologi;

    Sammanfattning : Antibodies have the ability to influence the antibody response against the very antigen they are specific for, in a process called antibody feedback regulation. Depending on the nature of the antigen, the antibody response can be either enhanced or almost completely inhibited. LÄS MER

  7. 5. Masking environmental feedback : Misfits between institutions and ecosystems in Belize and Thailand

    Författare :Miriam Huitric; Carl Folke; Nils Kautsky; Juan Carlos Castilla; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine reserves; ecosystem change; sequential exploitation; pathology of resource use; institutions; driving forces; coral reefs; social-ecological systems; mangroves; aquaculture; Belize; Thailand; Maine; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : The thesis analyses relationships between ecological and social systems in the context of coastal ecosystems. It examines human impacts from resource extraction and addresses management and governance behind resource exploitation. LÄS MER
