  2. 1. A Study of Some Temporal Properties of the Human Visual Evoked Potential, and Their Relation to Binocular Function

    Author : Björn Johansson; Peter Jakobsson; Anders Sjöström; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; VEP Visual Evoked Potential ; contrast sensitivity; binocularity; latency; Fourier analysis; strabismus; amblyopia; Ophtalmology; Oftalmologi;

    Abstract : As disturbed binocular functions in small children may lead to severe amblyopia it is of interest to detect it as early as possible. Most tests for binocular functions, however, demand active cooperation and may be unreliable in children up to 4-5 years of age. READ MORE

  4. 2. Affective responses to music in depressed individuals : Aesthetic judgments, emotions, and the impact of music-evoked autobiographical memories

    Author : Laura Stavroula Sakka; Patrik N Juslin; Urs Nater; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; depression; music listening; emotional reactions; emotion regulation; aesthetic judgment; cognitive bias; music-evoked autobiographical memories;

    Abstract : Music’s powerful influence on our affective states is often utilized in everyday life for emotion regulation and in music-therapeutic interventions against depression. Given this ability of music to influence emotions and symptoms in depressed people, it appears imperative to understand how these individuals affectively respond to music. READ MORE

  5. 3. Influence of depth of anesthesia on postoperative cognitive dysfunction (POCD) and inflammatory markers

    Author : Pether Jildenstål; Narinder Rawal; Lars Berggren; Jan Jakobsson; Johan Reader; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Postoperative cognitive dysfunction; minor and major surgery; anaesthesia; depth of anaesthesia monitoring; auditory evoked potential; AAI; inflammatory marker; Medicin; Medicine;

    Abstract : Patients may suffer from various forms of postoperative cognitive dysfunction (POCD). In most cases, the impact on cognitive function is relatively transient but POCD can sometimes be long-lasting (> 1 year). Studies showing that up to one in four patients with known risk factors are affected by some form of cognitive loss. READ MORE

  6. 4. Clinical Electrocochleography in Menière´s disease

    Author : Kornel Sass; Lund Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; intrathoracic pressure; perilymphatic fistula; pressure exposure; endolymphatic hydrops; Menière´s disease; reproducibility; specificity; sensitivity; rarefaction click; condensation click; electrocochleography; summating potential; Otorhinolaryngology; audiology; auditive system and speech; Otorinolaryngologi; audiologi; hörsel- och talorganen;

    Abstract : Electrocochleography (ECoG) is an objective method to evaluate cochlear electrophysiology. The recordings are considered to reflect the mechano-electric processes of the cochlea, and can indicate the presence of suspected endolymphatic hydrops. READ MORE

  7. 5. Chloride Homeostasis in Central Neurons

    Author : Tushar Yelhekar; Staffan Johansson; Michael Druzin; Merab Kokaia; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chloride concentration; current-voltage relation; interpolation; voltage ramp; reversal potential; [Cl–]i recovery; KCC2; extracellular matrix; GABAA receptor; chloride leak conductance; neurosteroid; fysiologi; Physiology;

    Abstract : The overall aim of the present thesis is to clarify the control of intracellular chloride homeostasis in central neurons, because of the critical role of chloride ions (Cl–) for neuronal function. Normal function of the central nervous system (CNS) depends on a delicate balance between neuronal excitation and inhibition. READ MORE
