2. 1. From Branes to Brains : On M-theory and Understanding Thermodynamics

   Author : Tom W. Adawi; Jon Ogborn; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; M-theory; p-branes; supersymmetry; duality; heat and temperature; phenomenography; context; Physics Education Research; Fysik; Fysikens didaktik; Physics; Fysik; Materiefysik; Physics of Matter; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

   Abstract : This thesis is concerned with research in both physics and physics education, and is divided into two parts.Part IString theory has been the leading candidate over the past few years for a theory that unifies all the fundamental forces of nature. READ MORE

4. 2. Human brains and virtual realities : Computer-generated presence in theory and practice

   Author : Daniel Sjölie; Lars-Erik Janlert; Johan Eriksson; Giuseppe Riva; Umeå universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human brain function; virtual reality; presence; cognitive neuroscience; human-computer interaction; brain imaging; fMRI; BCI; neural correlates; HCI theory; reality-based interaction.;

   Abstract : A combined view of the human brain and computer-generated virtual realities is motivated by recent developments in cognitive neuroscience and human-computer interaction (HCI). The emergence of new theories of human brain function, together with an increasing use of realistic human-computer interaction, give reason to believe that a better understanding of the relationship between human brains and virtual realities is both possible and valuable.

5. 3. Brains, genes and environment of suicide attempters

   Author : Fredrik Vang; Lund Psykiatri; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; suicide; attempted suicide; self-injury; factor analysis; psychometrics; suicide assessment scale; cortisol; hpa-axis; hypothalamic-pituitary-adrenal axis; depression; adjustment disorder; serotonin transporter; 5HTTLPR; adversities; negative life events; globus pallidus; caudate nucleus; SPECT; MRI; volumetry; dichotic listening; brain lateralization; functional brain asymmetry;

   Abstract : Identification of symptoms or biological abnormalities that predispose to suicide or identifies specific vulnerabilities, may one day improve allocation of resources or help tailor treatment to the patient. Paper I: We compared the predictive value of symptom-oriented questions against direct questions about suicidality in assessing risk for suicide attempts. READ MORE

6. 4. The evolution of social cognition in Archosauria : Gaze following and play as windows to social cognition in dinosaurs

   Author : Claudia Zeiträg; LUCS grupp för kognitiv zoologi; []
   Keywords : HUMANIORA; HUMANITIES; evolution of cognition; dinosaurs; archosaurs; social cognition; avian brains; gaze following; play; development;

   Abstract : Social cognition entails all cognitive processes involved in social interactions. To study the evolution of social cognition, it is crucial to investigate several distantly related lineages. READ MORE

7. 5. A study of neuropeptide Y in brains of 'depressed' and healthy rats

   Author : Patricia A Jimenez Vasquez; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Neuropeptide Y; Depression; Animal Models of Depression Antidepressant treatments;

   Abstract : Neuropeptide Y (NPY), a 36-amino acid peptide that was originally isolated from mammalian brain tissue, is widely distributed in both rat and human brain. NPY has a number of physiological actions and affects for example hypothalamic-pituitary-adrenal (HPA)-axis and circadian rhythms, modulates memory processing and food intake. READ MORE
