1. Generation of cortical neurons through reprogramming technology
Sammanfattning : The human cortex is affected by several debilitating acute and chronic neurodegenerative disorders such as stroke, traumatic brain injury, amyotrophic lateral sclerosis and Alzheimer’s disease, which target specific types of cortical neurons. Emerging evidence indicates that stem cells and reprogrammed cells can be used to generate human cortical neurons both for cell replacement by transplantation, and for disease modeling and drug screening.

2. Neocortical interpretation of haptic and visual events across brain states: Electrophysiological investigations in sensory information processing
Sammanfattning : This thesis delves into the complex architecture of dynamic sensory information processing in the neocortex. Specifically, it asks how primary sensory cortical regions are influenced by local and widespread cortical state changes. LÄS MER
3. Postischaemic superficial renal cortical microcirculation : experimental studies in the pig performed by laser Doppler flowmetry and measurement of tissue oxygenation
Sammanfattning : .... LÄS MER
4. Active Memory Processing on Multiple Time-scales in Simulated Cortical Networks with Hebbian Plasticity
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. Affective touch throughout life: from cortical processing in infancy to touch perception in adulthood
Sammanfattning : Affective, interpersonal touch is important for forming and maintaining social bonds. In the hairy skin of humans there is a specific type of nerve fibers called C-tactile (CT) afferents which are optimally activated by a light stroking of the skin, like a caress. LÄS MER
