2. 1. Brain morphology and behaviour in the guppy (Poecilia reticulata) : Effects of plasticity and mosaic brain evolution

   Author : Stephanie Fong; Niclas Kolm; Björn Rogell; Stephen Montgomery; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; brain plasticity; cognition; reversal learning; spatial learning; directed selection; mosaic brain; heritability; brain morphology; boldness; relative telencephalon size; inhibitory control; detour task; Poecilia reticulata; etologi; Ethology;

   Abstract : Understanding how brains have evolved and subsequently culminated in the huge variation in brain morphology among contemporary vertebrate species has fascinated researchers for many decades. It has been recognized that brain morphology is both genetically and environmentally determined. READ MORE

4. 2. Delayed Cell Death after Traumatic Brain Injury : Role of Reactive Oxygen Species

   Author : Fredrik Clausen; Lars Hillered; Tiit Mathiesen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Traumatic Brain Injury; Reactive oxygen species; Fluid percussion injury; Controlled cortical impact; weight drop injury; Extracellular-signal regulated kinase; apoptosis; free radical scavenging; morphology; functional outcome; Neurovetenskap; Neurology; Neurologi;

   Abstract : Traumatic brain injury (TBI) is a leading cause of death and disability TBI survivors often suffer from severe disturbances of cognition, memory and emotions. Improving the treatment is of great importance, but as of yet no specific neuroprotective treatment has been found. READ MORE

5. 3. Intracranial Pressure in Traumatic Brain Injury

   Author : Sima Shahsavari; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Brain Swelling; Cerebral Autoregulation; Secondary Brain Injury; Traumatic Brain Injury; Cerebral Compliance; Intracranial Dynamics; Intracranial Pressure;

   Abstract : Traumatic Brain Injury (TBI) continues to be a major problem worldwide. Today, intensive care of patients with TBI is mainely focused on preventing and treating secondary brain injuries. High pressure inside the intracranial cavity (ICP) has been found to be an important feature of disturbed cerebral dynamics and secondary injuries. READ MORE

6. 4. Chemical signalling in the Drosophila brain : GABA, short neuropeptide F and their receptors

   Author : Lina E. Enell; Dick Nässel; Jonathan Bacon; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Insect nervous system; Drosophila; GABA; sNPF; GPCR; ion channel receptor; feeding; metabolic stress; olfaction; antennal; lobe; mushroom body; Morphology; Morfologi; funktionell morfologi; Functional Zoomorphology;

   Abstract : Gamma-aminobutyric acid (GABA) and short neuropeptide F (sNPF) are widespread signalling molecules in the brain of insects. In order to understand more about the signalling and to some extent start to unravel the functional roles of these two substances, this study has examined the locations of the transmitters and their receptors in the brain of the fruit fly Drosophila melanogaster using immunocytochemistry in combination with Gal4/UAS technique.

7. 5. Through the magnifying glass - The big small world of marine meiofauna : Morphology, species and evolution in Nemertodermatida

   Author : Inga Meyer-Wachsmuth; Ulf Jondelius; Mark E Sidall; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nemertodermatida; Acoelomorpha; morphology; CLSM; Phalloidin; musculature; DNA; cryptic species; species delimitation; dispersal; taxonomy; phylogenetics; IHC; nervous system; Systematic Zoology; zoologisk systematik och evolutionsforskning;

   Abstract : Nemertodermatida is a group of microscopic marine worm-like animals that live as part of the marine meiofauna in sandy or muddy sediments; one species lives commensally in a holothurian. These benthic worms were thought to disperse passively with ocean currents, resulting in little speciation and thus wide or even cosmopolitan distributions. READ MORE
