  1. 11. Plasticity and variation of synaptic responses in hippocampus. Role of AMPA and NMDA receptors

    Författare :Yin-Ping Niu; Göteborgs universitet; []
    Nyckelord :learning and memory; synaptic plasticity; hippocampus; synapse; AMPA receptor; NMDA receptor; LTP; LTD; CV; TFS;

    Sammanfattning : It is generally believed that synaptic plasticity in the central nervous system may underlie learning and memory as well as neuronal development. The most wellstudied examples of such synaptic plasticity are long-term potentiation (LTP) andlong-term depression (LTD). LÄS MER

  4. 13. Magnetic properties of hard-soft amorphous nanolaminates

    Författare :Parul Rani; Gabriella Andersson; Petra Jönsson; Kostas Sarakinos; Erik Wahlström; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Amorphous Thin Film; Soft Hard Multilayers; Combinatorial Sputtering; Magnetism; Rigid-Exchange coupling; First-Order Reversal Curve; Fysik; Physics;

    Sammanfattning : Amorphous magnetic thin film heterostructures and multilayers are often used in data storage as well as spintronic devices. Spintronics will help the next generation of nano-electronic devices to increase their memory and processing power and reduce their power consumption. LÄS MER

  5. 14. Aspects of Frontal and Medial Temporal Brain Functions : Neuropsychological and functional imaging studies in normals and in frontotemporal dementia

    Författare :Christina Elfgren; Institutionen för psykologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; neurophysiology; regional cerebral blood flow; Neuropsychological assessment; frontotemporal dementia; normal subjects; frontal lobes; medial temporal lobes; neuropsychology; Neurology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : The thesis is based on five investigations. In the first study the nature and the degree of cognitive impairment of patients with frontotemporal dementia (FTD) is explored. The results from neuropsychological assessment are described as three levels of cognitive impairment. LÄS MER

  7. 15. CMOS circuits for digital RF systems

    Författare :Ingemar Söderquist; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis describes some high performance CMOS circuits and architectures developed for digital signal processing of Radio Frequency (RF) signals. Experimental results are demonstrated in a generic radar jammer architecture. LÄS MER
