3. 2. Cross-functional brain imaging of attention, memory, and executive functions : Unity and diversity of neurocognitive component processes

   Författare :Petter Marklund; Lars Nyberg; Akira Miyake; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Human memory; executive functions; prefrontal cortex; sustained and transient neural activity; declarative long-term memory; attention; working memory; functional neuroimaging; cognitive control.; Psychology; Psykologi;

   Sammanfattning : The central theme of the present thesis revolves around the exploration of similarities and differences in brain activity patterns invoked by the component processes underlying mnemonic, executive and attentional functions. The primary aim was to identify and functionally characterize commonly recruited brain regions in terms of shared component processes, which has been a largely neglected area of research in cognitive neuroscience.

4. 3. Active Memory Processing on Multiple Time-scales in Simulated Cortical Networks with Hebbian Plasticity

   Författare :Florian Fiebig; Anders Lansner; Tim Vogels; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Working memory; Long-term memory; consolidation; spiking; neural network; BCPNN; cortical microcircuit; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics; Biological Physics; Biologisk fysik;

   Sammanfattning : This thesis examines declarative memory function, and its underlying neural activity and mechanisms in simulated cortical networks. The included simulation models utilize and synthesize proposed universal computational principles of the brain, such as the modularity of cortical circuit organization, attractor network theory, and Hebbian synaptic plasticity, along with selected biophysical detail from the involved brain areas to implement functional models of known cortical memory systems.

5. 4. Livet som figur : om självbiografiskt minne och metaforer

   Författare :Monika Bredefeldt Öhman; Kognitionsvetenskap; []
   Nyckelord :HUMANIORA; HUMANITIES; lexical decision task; image schema; force dynamics; cognitive semantics; Autobiographical memory; balance; life story; metaphor; narrative;

   Sammanfattning : The central topics of the thesis are autobiographical memory and metaphors. Three hypotheses are presented: (1) Autobiographical memory is better understood without dichotomizing the declarative (explicit) long-term memory system into semantic and episodic. LÄS MER
