1. 1. Neural Entrainment to Speech Analyzed with EEG : A Review of Contemporary Theories about the Underlying Mechanisms of Speech Processing

   Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Richard Larsson; [2017]
   Nyckelord :EEG; neural entrainment; cortical entrainment; neural oscillation; cortical oscillation; speech;

   Sammanfattning : Neural entrainment quite recently became considered an important mechanism used by the brain to process stimuli with periodic qualities, such as the frequency and duration time of signals reaching sensory organs. An increasing amount of data strongly implies that the brain might be using neural entrainment as a mechanism to either directly process speech and/or to facilitate speech interpretation. LÄS MER

3. 2. Catch the dream Wave : Propagation of Cortical Slow Oscillation to the Striatum in anaesthetised mice

   Master-uppsats, KTH/Beräkningsbiologi, CB

   Författare :Tiago Ferreira; [2014]
   Nyckelord :Cortex; Striatum; anaesthesia; slow oscillation; spontaneous activity; ketamine; in vivo; up states; wavelet; MUA; high-gamma range; MSNs;

   Sammanfattning : Under anaesthesia or in deep sleep, different parts of the brain have a distinctive slow oscillatory activity, characterised by states of high membrane potential and intensive spiking activity, the Up-states; followed by hyperpolarisation and quiescence, the Down-states. This activity has been previously described in vitro and in vivo in the cortex and the striatum, across several species. LÄS MER
