1. Physical activity, bone gain and sustainment of peak bone mass
Abstract : Weak and osteoporotic bones are an increasing cause of mortality and painful physical impairment among the elderly, especially in the Western world. Bone mineral density (BMD, g/cm2) accrual during childhood and adolescence is thought to influence an individual’s risk of osteoporosis and the related fractures. READ MORE

2. Neocortical interpretation of haptic and visual events across brain states: Electrophysiological investigations in sensory information processing
Abstract : 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. READ MORE

3. The physiological processing of Alzheimer-associated amyloid beta precursor protein in human and animal-derived neuronal models
Abstract : Alzheimer’s disease (AD) is characterized by cognitive impairment due to the loss of structure and/or function of neurons, and amyloid plaques composed of aggregated-amyloid beta (Aβ) peptides, primarily species ending at the amino acid 42 (Aβ42), are one of the major neuropathological hallmarks of AD. Aβ peptides of different lengths are produced by sequential cleavage of amyloid beta precursor protein (APP) by α-, β- and γ- secretases. READ MORE

4. The role of physical activity on bone density and bone geometry in men
Abstract : THE ROLE OF PHYSICAL ACTIVITY ON BONE DENSITY AND BONE GEOMETRY IN MEN Introduction: Several studies indicate that peak bone mass, reached during the third decade in life, is an important determinant of osteoporosis later in life. Physical activity with dynamic loading of the bone is an important determinant of peak bone mass. READ MORE

5. Active Memory Processing on Multiple Time-scales in Simulated Cortical Networks with Hebbian Plasticity
Abstract : 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.
