»What we know (and do not know) about prepulse inhibition of startle«


The startle reflex is a phylogenetically old and very sensitive constellation of responses that serve both defensive and interruptive properties. Startle can be measured in a range of animal models, and in humans across the lifespan. This response is very sensitive to variations in stimulus and situational parameters, personality characteristics, clinical diagnoses, and pharmacological, social, and cognitive situations. One intriguing property of startle is the fact that it can be profoundly inhibited by the presentation of an otherwise innocuous stimulus, called a prepulse, shortly before the startle stimulus. This prepulse inhibition (PPI) of startle is a very reliable and robust effect, attenuating the startle response completely in many cases. PPI can vary based on a multitude of stimulus, situation, and person parameters, and some of those factors will be discussed in this presentation. Information about the sensitivity and utility of PPI will also be provided, suggesting applications in a variety of areas in psychology and neuroscience. An effort will also be made to correct some misconceptions about PPI, and to point toward future developments in the application of this exceedingly sensitive and useful measure.

»Lernen, Gedächtnis und Plastizität des Gehirns: Implikationen für Verhaltensänderung«

Lern- und Gedächtnisprozesse und damit einhergehende maladaptive plastische Veränderungen des Gehirns spielen bei der Entstehung pychischer Störungen, und spezifisch bei chronischen Schmerzen, eine entscheidende Rolle. Dabei dürfte das Hauptproblem die Unfähigkeit sein, aversive Gedächtnisinhalte zu löschen, die sowohl explizite wie auch implizite Gedächtnisspuren umfassen. Der dominante psychologische Zugang zu diesen Störungen ist kognitiv-verhaltenstherapeutisch. Jedoch fokussieren diese Trainings auf eine Verminderung von Einschränkungen und die Bildung von Bewältigungsfertigkeiten. Auf der Basis der Evidenz für Gedächtnisprozesse in der Psychopathologie könnten hirnbasierte Exztinktionsverfahren und sensomotorische Trainings alternative und eher an den Mechanismen orientierte Behandlungsalternativen für emotionale und sensorische Störungen sein,  die durch extinktionsfördernde pharmakologische Interventionen verstärkt warden können. Wenn Personen lernen können, spezifische Hirnregionen zu beeinflussen, so hat das auch Implikationen für periphere Prozesse wie die Muskelspannung oder für die Körperwahrnehmung. Somit lassen sich diese Prinzipien auch auf die Behandlung von Immobilität nach Verletzungen oder chronischen Krankheiten sowie pathologische Altersprozesse wie Gebrechlichkeit oder Demenz übertragen. Dabei sind motivationale Aspekte besonders wichtig, die sich durch virtiuelle Realität und Spielumgebungen realisieren lassen.

»Bidirectional effects of early life adversity on stress system regulation – in search for a comprehensive theory«

Early life adversity (ELA), in the form of low parental care or overprotection, or physical, sexual, or emotional abuse, is consistently linked to poor mental health outcomes in adulthood, including psychosis, depression, and burnout. A generally agreed-upon mediator of these effects is a changed regulation of the stress /energy systems in the organism, namely the autonomic nervous system (ANS), and the hypothalamic-pituitary adrenal (hpa) axis. Investigated in both human and animal studies, these systems are consistently found dysregulated in organisms exposed to ELA, however the directionality is unclear, with some studies demonstrating heightened activity, while others show blunting of the biomarkers of the system, after exposure to adversity early in life.

Several theories exist that try and explain these mixed effects, considering factors like age of exposure, trauma severity, duration, or type. Importantly, none of the theories can be used to explain all of the available data, suggesting that additional factors / mediators might be at play.

The current talk will summarize the major theories in the field and point out some of the commonalities and differences among them. In addition, it will introduce potential mediators that are currently not incorporated in the theories but that might be important to consider to better understand the ELA / stress response system relationship.
