  1. 1. Cognition Seen Through the Eyes of Hearing Aid Users : Working Memory Resource Allocation for Speech Perception and Recall

    Författare :Andreea Micula; Jerker Rönnberg; Elaine Hoi Ning Ng; Piers Dawes; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Working memory; Free recall; Pupillary responses; Noise reduction; Arbetsminne; Återgivning; Pupillmätning; Brusreducering;

    Sammanfattning : This thesis investigates how hearing aid users allocate working (WM) memory resources under various task demands when listening to and storing speech in memory for later recall. This was done by combining an auditory recall task, the Sentence-final Word Identification and Recall (SWIR) test, with pupillometry. LÄS MER

  3. 2. Selective wavelength pupillometry to evaluate outer and inner retinal photoreception

    Författare :Aki Kawasaki; Fatima Pedrosa Domellöf; Bertil Lindblom; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pupil; pupil light reflex; melanopsin; photoreceptor; intrinsically photosensitive retinal ganglion cell; oftalmiatrik; Ophtalmology;

    Sammanfattning : PurposeIntrinsically photosensitive retinal ganglion cells (ipRGCs) express a unique photopigment called melanopsin. Capable of direct phototransduction, the ipRGCs are also influenced by rods and cones via synaptic inputs. LÄS MER

  4. 3. Multisensory control of gaze stabilization : from brainstem to bedside

    Författare :Tobias Wibble; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Without the continuous updates provided by the vestibular and visual systems, our world would appear blurry and unstable. In order to allow the retina to reliably record incoming light in a meaningful way, the vestibulo-ocular reflex (VOR) and optokinetic reflex (OKR) aim to stabilize our gaze on visual features.

  5. 4. Regulation of human pancreas hormone secretion by autonomic innervation

    Författare :Rayner Rodriguez-Diaz; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Diabetes mellitus is a silent killer doing away with one person every 10 seconds. We speak of diabetes when the organism cannot control the right level of glucose in the blood. The hormones insulin and glucagon secreted by the islets of Langerhans are the major players maintaining glucose homeostasis. LÄS MER
