  1. 1. Tree Rings as Sensitive Proxies of Past Climate Change

    University dissertation from Stockholm : Institutionen för naturgeografi och kvartärgeologi

    Author : Håkan Grudd; Stockholms universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tree ring; width; density; climate; temperature; change; variability; sensitivity; Torneträsk; Tornetrask; Sweden; Fennoscandia; explosive; volcanic; eruption; Santorini; Thera; subfossil; Fitzroya; Chile; NATURAL SCIENCES Earth sciences Exogenous earth sciences Physical geography; NATURVETENSKAP Geovetenskap Exogen geovetenskap Naturgeografi;

    Abstract : In the boreal forests of the Northern Hemisphere, time series of tree-ring width (TRW) and maximum density in the latewood (MXD) are highly correlated to local instrumental summer-temperature data and are thus widely used as proxies in high-resolution climate reconstructions. Hence, much of our present knowledge about climatic variability in the last millennium is based on tree-rings. READ MORE

  4. 4. On the role of forebrain cholinergic innervation for phencyclidine-induced behaviors and gene expression patterns

    University dissertation from Stockholm : Karolinska Institutet, Dept of Neuroscience

    Author : Sophia Savage; Karolinska Institutet.; Karolinska Institutet.; [2013]

    Abstract : The basalo - cortical cholinergic innervation reaches neural targets in cortex cerebri where it modulates the incoming sensory information, regulating arousal, attention, v igilance, memory and cognition. P rogressive de generation of the cholinergic neurons in the basal forebrain is considered a hallmark of Alzheimer ’s disease re lated to cognitive impairment in this condition. READ MORE
