  2. 1. Neural and behavioral plasticity in olfactory sensory deprivation

    Author : Moa Peter; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The human brain has a remarkable ability to reorganize as a consequence of altered demands. This ability is particularly noticeable when studying the neural effects of complete sensory deprivation. READ MORE

  4. 2. Brain morphology and behaviour in the guppy (Poecilia reticulata) : Effects of plasticity and mosaic brain evolution

    Author : Stephanie Fong; Niclas Kolm; Björn Rogell; Stephen Montgomery; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; brain plasticity; cognition; reversal learning; spatial learning; directed selection; mosaic brain; heritability; brain morphology; boldness; relative telencephalon size; inhibitory control; detour task; Poecilia reticulata; etologi; Ethology;

    Abstract : Understanding how brains have evolved and subsequently culminated in the huge variation in brain morphology among contemporary vertebrate species has fascinated researchers for many decades. It has been recognized that brain morphology is both genetically and environmentally determined. READ MORE

  5. 3. Sequence learning in the Bayesian Confidence Propagation Neural Network

    Author : Ramon Heberto Martinez Mayorquin; Pawel Herman; Anders Lansner; Matthias Hennig; Thomas Wennekers; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bayesian; learning; neural networks; sequences; Computer Science; Datalogi;

    Abstract : This thesis examines sequence learning in the Bayesian Confidence PropagationNeural Network (BCPNN). The methodology utilized throughout this work is com-putational and analytical in nature and the contributions here presented can beunderstood along the following four major themes: 1) this work starts by revisitingthe properties of the BCPNN as an attractor neural network and then provides anovel formalization of some of those properties.

  6. 4. Temporal dynamics of brain and hormone changes during parr-smolt transformation in salmon

    Author : Lars Ebbesson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; animal morphology; Animal anatomy; growth hormone; metamorphosis; thyroid hormones; neural plasticity; Djurs anatomi och morfologi;

    Abstract : This thesis describes a series of studies designed to elucidate brain circuitry changes during parr-smolt transformation (smoltification) in salmon. The studies revealed sequential orderly chemical and structural changes of the brain. READ MORE

  7. 5. Neurotrophic factors and neuronal plasticity

    Author : Sten Linnarsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The neurotrophic factors were originally discovered because of their ability to rescue neurons during a period of naturally occurring programmed cell death. This gave rise to the neurotrophic factor hypothesis which states that specific target-derived factors protect and support subpopulations of innervating neurons, thereby regulating the pattern and quantity of innervation properly for each target tissue.
