  2. 1. Brain characteristics of memory decline and stability in aging : Contributions from longitudinal observations

    Author : Sara Pudas; Jonas Persson; Lars Nyberg; Emrah Düzel; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; aging; episodic memory; individual differences; longitudinal assessment; magnetic resonance imaging; hippocampus; frontal cortex; Psychology; psykologi;

    Abstract : Aging is typically associated with declining mental abilities, most prominent for some forms of memory. There are, however, large inter-individual differences within the older population. Some people experience rapid decline whereas others seem almost spared from any adverse effects of aging.

  4. 2. Decoding the complex brain : multivariate and multimodal analyses of neuroimaging data

    Author : Alireza Salami; Lars Nyberg; Cheryl Grady; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multivariate analysis; univariate analysis; multimodal imaging; episodic memory; aging; functional magnetic resonance imaging; diffusion tensor imaging; biology; biologi; Psychology; psykologi; datoriserad bildanalys; Computerized Image Analysis;

    Abstract : Functional brain images are extraordinarily rich data sets that reveal distributed brain networks engaged in a wide variety of cognitive operations. It is a substantial challenge both to create models of cognition that mimic behavior and underlying cognitive processes and to choose a suitable analytic method to identify underlying brain networks.

  5. 3. Neurogenesis and transplantation in stroke-damaged brain

    Author : Vladimer Darsalia; Lund Neurologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neuropsychology; neurophysiology; Neurologi; Neurology; Stroke; Transplantation; Stem cells; Aging; Neurogenesis; neurofysiologi;

    Abstract : Stroke in young adult rodents triggers neurogenesis in the damaged striatum and intact hippocampus. as stroke happens frequently in aged individuals it is of great importance to know whether aging affects brain recovery mechanisms. READ MORE

  6. 4. Effects of adult aging on socioemotional perception : Evidence from behavior and brain

    Author : Diana Persson; Håkan Fischer; Petri Laukka; Louise Phillips; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; age-related differences; social attributes; emotion recognition; oxytocin; fMRI; Psychology; psykologi;

    Abstract : Social perception plays a key role in our everyday interactions. It encompasses the ability to identify, understand, and react to the social cues that others express. READ MORE

  7. 5. Advanced Mass Spectrometry Imaging in Neuropharmacology

    Author : Theodosia Vallianatou; Per E. Andrén; Anna Nilsson; Mohammadreza Shariatgorji; Maria Karlgren; Irena Loryan; Nathalie Agar; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mass spectrometry imaging; neuropharmacology; blood brain barrier; drug-drug interactions; aging; tacrine;

    Abstract : Mass spectrometry imaging (MSI) has emerged as a valuable approach for mapping multiple molecular species in sections of diverse tissues. It enables simultaneous detection of numerous compounds (from neurotransmitters to small proteins) in the brain at relatively high lateral resolution (>5 μm) on a routine basis. READ MORE
