Habilitation – Sebastian Ocklenburg

Sebastian Ocklenburg successfully habilitated on the 12th of November 2014 in the Faculty of Psychology for the field of “Cognitive Neuroscience”. His written thesis already had impressed everybody by its clear focus on cerebral asymmetries and its breadth within this area of analysis. Now, he performed equally well with his oral presentation on why white matter matters. Sebastian’s presentation was absolutely lucid and perfect. He could subsequently answer all emerging questions in the best possible way. Altogether, this was a very strong presentation and the committee unanimously decided that Sebastian Ocklenburg should be awarded with the habilitation of the Faculty of Psychology.

 

CONGRATULATIONS SEBASTIAN !!!

Neurons in the pigeon nidopallium caudolaterale signal the selection and execution of perceptual decisions

In the recently published paper we focused on the investigation of generality in neural mechanisms underlying perceptual decision making across species. Therefore, we recorded single-neuron activity in the pigeon nidopallium caudolaterale (NCL). This area is a non-laminated associative forebrain structure thought to be functionally equivalent to mammalian prefrontal cortex. The freely moving subject performed a well established visual categorisation task. Whereas the majority of NCL neurons unspecifically upregulated or downregulated activity during stimulus presentation, ~20% of neurons exhibited differential activity for the sample stimuli and predicted upcoming choices. Moreover, neural activity in these neurons was ramping up during stimulus presentation and remained elevated until a choice was initiated. This response pattern is similar to that found in monkey prefrontal and parietal cortices in saccadic choice tasks. In addition, many NCL neurons coded for movement direction during choice execution and differentiated between choice outcomes (reward and punishment). By means of these results we further implicate the NCL to be involved in the selection and execution of operant responses, an interpretation resonating well with the results of previous lesion studies. The resemblance of the response patterns of NCL neurons to those observed in mammalian cortex suggests that, despite differing neural architectures, mechanisms for perceptual decision making are similar across classes of vertebrates.

Geist – Gehirn – Genom – Gesellschaft: Wie wurde ich zu der Person, die ich bin?

Die Frage „Wie wurde ich zu der Person, die ich bin?“ betrifft jeden ganz unmittelbar. Wenn man möglichst umfassend verstehen will, welche Bedingungen, Prozesse und Einflussfaktoren dazu beitragen, dass wir in der Interaktion mit unserer Umwelt zu einzigartigen Individuen werden, muss man das Panorama des gegenwärtigen Wissens über die natürlichen und kulturellen Wurzeln menschlicher Individualität aus den unterschiedlichsten wissenschaftlichen Perspektiven betrachten. Alte Erklärungsmodelle, die Eigenschaften und Leistungsvermögen eines Menschen entweder auf das Erbgut oder auf Umwelteinflüsse zurückführten, werden abgelöst durch neue Erkenntnisse über die Wechselwirkung dieser Faktoren. Doch wie genau resultiert der einzelne Mensch aus der Ko-Konstruktion von Geist, Gehirn, Genom und Gesellschaft? Die Leopoldina hatte ihre Jahresversammlung 2013 dieser Frage gewidmet. Unter dem Motto „Geist – Gehirn – Genom – Gesellschaft. Wie wurde ich zu der Person, die ich bin?“ haben vom 20. bis 22. September 2013 in Halle Vertreter der unterschiedlichsten Disziplinen aus Sicht ihrer Fachgebiete dargestellt, wie wir Individuen aus dem Zusammenspiel von Geist, Gehirn, Genom und Gesellschaft resultiert. Nun ist der Tagungsband erschienen, der fast alle auf der Jahresversammlung gehaltenen Vorträge enthält (Güntürkün, O., Hacker, J. (Hrsg.), Nova Acta Leopoldina Nr. 405, Band: 120, Geist – Gehirn – Genom – Gesellschaft: Wie wurde ich zu der Person, die ich bin? Wissenschaftliche Verlagsgesellschaft Stuttgart, 2014.).

dasGehirn.INFO informs about FOR 1581

The online magazine www.dasGehirn.info informs the reader about findings of brain research in an entertaining and comprehensive way. In cooperation with the research groups FOR 1581 and SFB 636 they present extinction learning as one of the most exciting current research topics between mind and brain. As old knowledge is persistent - especially under stress -, the initial process of acquisition of new knowledge is well studied, but the process of extinction is far less understood. Read more.
