Beschreibung: Spermidin ist ein Polyamin, das wir über die Nahrung aufnehmen (z.B. in Weizenkeimen, Broccoli, Erbsen, etc.). Es gibt Hinweise darauf, dass Spermidin in hoher Konzentration die Autophagie anregt. Nach ersten Überlegungen sollte das positive Auswirkungen auf die Hirnalterung haben und könnte so protektiv gegen Demenzerkrankungen eingesetzt werden. In der Bachelorarbeit sollen diese Überlegungen anhand aktueller Literatur überprüft werden.

Beschreibung: mergence of alpha oscillations (8-12 Hz) is typically observed in the electroencephalogram (EEG) during eye-closed resting states. It is thus widely accepted that alpha oscillations are indicative of cortical idleness. However, alpha waves may play a relatively active role under certain circumstances, e.g., they help protect the content of working memory from the interference of irrelevant information. In this thesis, you will have the opportunity to gain a comprehensive understanding of the emergence, characteristics, and functional significance of alpha waves during working memory.

Beschreibung: ur subjective perception of time often differs from its objective definition in physics. Time, as we perceive it, is characterized by a high level of granularity. For instance, people struggle to determine the temporal sequence of two successive visual stimuli when the time gap between them is reduced to 20-60 milliseconds. This phenomenon is known as the temporal order threshold, and its threshold varies across sensory modalities and specific tasks. What underlies the brain's limited temporal resolution? Is there a neural mechanism that defines the temporal framework in the brain, and is it specific to certain sensory modalities or a universal center governing all cognitive processes? This thesis offers a comprehensive exploration of time perception within the domain of sub-100 milliseconds.
