DENDRITES 2024

21.05. – 24.05.2024
Platanias, Chania, Crete, Greece
Workshop

Principles of dendritic function and computation:
Understanding how brains generate perception and drive behaviour while being energetically efficient is still one of the biggest challenges of our century. Neurons communicate via synaptic inputs which are located on thin branches known as dendrites which shape how we respond to the external world, encode memories, and generate behaviour. Recent technical developments have enabled the study of dendrites at multiple levels, from the organization and plasticity of single synaptic inputs to dendritic computations in behaviour. The goal of this workshop is to bring together international scientific leaders who work on molecular, biophysical, anatomical, computational and/or functional aspects of dendrites to further our understanding of how these beautiful structures contribute to different brain functions and their abnormalities.

NEXTEN: Envisaging Theoretical and Computational Neuroscience for the next 10 years

16.05. – 17.05.2024
St. Louis, USA
Conference

Theoretical/Computational Neuroscience is currently undergoing a phase of unprecedented growth. Dramatic advances in the ease with which large-scale datasets of behavior, neural activity, connectomic and gene expression information can be collected have coincided with a revolution in the capabilities of Artificial Intelligence-based algorithms to interrogate such datasets. Concurrently, these new datasets are inspiring exciting new developments in mathematical tools for extracting their underlying structure and relationships. What is the current state of the art in our theoretical/computational understanding of the brain, and what does the future hold? You are invited to join an exciting line-up of leaders in the field to address these questions.

Ringvorlesung Wintersemester 2023/2024 – Herz und Hirn gemeinsam im Fokus

07.11. – 06.02.2024
Göttingen, Germany
Ringvorlesung

Herz und Hirn gemeinsam im Fokus

Erkrankungen des Herzens und des Gehirns gehören zu den häufigsten Todesursachen weltweit. Manche Erkrankungen betreffen sogar beide Organe. Obgleich Herz und Gehirn auf den ersten Blick sehr unterschiedlich erscheinen, weisen ihre elektrisch erregbaren Hauptzellen viele Gemeinsamkeiten auf. Beide verwenden ähnliche Funktionseinheiten, die der Erregbarkeit der Zellen dienen und über die sie physiologische Leistungen als Teil aktiver Netzwerke erbringen. Fehlfunktionen dieser Nanometer-kleinen Einheiten führen oft zu Erkrankungen.

Ziel des Göttinger Exzellenzclusters „Multiscale Bioimaging: von molekularen Maschinen zu Netzwerken erregbarer Zellen“ (MBExC) ist, diese Funktionseinheiten von Herz- und Nervenzellen zu verstehen, um daraus neue Diagnostik- und Therapieansätze entwickeln und gesellschaftlich relevante Fragen in der Herz- und Hirnforschung beantworten zu können.

Im Rahmen der Ringvorlesung gewähren MBExC-Wissenschaftler*innen am Beispiel spannender Forschungsergebnisse umfassende Einblicke in den einzigartigen Forschungsansatz des Clusters. Sie stellen innovative Technologien vor, die ihren Ursprung oft in Göttinger Pionierarbeiten haben und am MBExC weiterentwickelt werden, und zeigen auf, wie genau man heutzutage in das Gewebe und die Zelle „hineinschauen“ kann. All diese Technologien liefern uns einzigartige Einblicke in unser Herz und unser Gehirn.

EMBO Workshops: Subcortical sensory circuits: visual, auditory, somatosensory, and beyond

28.11. – 01.12.2023
EMBL Heidelberg and virtual
Conference

Subcortical sensory circuits play a fundamental role in the perception of the outside world. However, they are often thought of as relay stations that passively transmit sensory information to the cortex or simple effectors of behavioral reflexes. Recent studies, however, suggest that subcortical pathways also perform sophisticated computations, such as integrating peripheral information among many sensory pathways and the animal’s internal states. This meeting will gather leading researchers in the field to discuss different subcortical circuits involving various sensory modalities and revisit their increasingly complex and interconnected contributions to perception, behavior, and cognition. Furthermore, we will delve into various topics which often play an interconnected role with sensory perception and are crucial to a detailed yet holistic understanding of perceptual circuits.

Konstanz School of Collective Behaviour (KSCB)

31.07. – 12.08.2023
Constance, Germany
School

Collective behaviour is all around us from flocks of birds to schools of fish to human crowds. Collective behaviour happens across multiple spatial and temporal scales making it one of the most ubiquitous, natural phenomena around us. For a long time, organismal collective behaviour has been studied separately across many disciplines from biology to ecology to physics to engineering. The aim of this school is to bring multiple disciplinary approaches to collective behaviour, studying a wide variety of organisms using different methods. The school thus aims to prepare the next generation of scientists that are exposed to a breadth of approaches to study collective behaviour.

Neural Systems & Behavior

03.06. – 30.07.2023
Chicago, USA
Course

This course provides broad training in modern approaches to the study of neural mechanisms underlying behavior, perception, and cognition. Through a combination of lectures, exercises, and projects, students investigate neural systems at the molecular, cellular, and organismal levels using state-of-the-art techniques. The eight weeks are divided into two-week cycles, providing participants with an in-depth familiarity with several different experimental model systems. In the first cycle, students study a simple invertebrate model system to develop general experimental skills in electrophysiology, neuroanatomy, and quantitative analysis of physiological and behavioral data. In subsequent cycles, students work on a series of different preparations, providing them with a breadth of knowledge in the field. The list of experimental model systems is updated year-to-year, but always includes a diverse array of vertebrate and invertebrate preparations, chosen to illustrate key concepts and novel techniques in the field. The goal of the course is to expose students to diverse approaches to the investigation of the neural basis of behavior.

GEM 2023

12.06. – 14.06.2023
Bochum, Germany
Conference

Episodic memories are widely regarded as memories of personally experienced events. Early concepts about episodic memory were based on the storage model, according to which experiential content is preserved in memory and later retrieved. However, overwhelming empirical evidence suggests that the content of episodic memory is – at least to a certain degree – constructed in the act of remembering. Even though very few contemporary researchers would oppose this view of episodic memory as a generative process, it has not become the standard paradigm of empirical memory research. This is particularly true for studies of the neural correlates of episodic memory. Further hindering progress are large conceptual differences regarding episodic memory across different fields, such as neuroscience, philosophy, and psychology. This interdisciplinary conference therefore aims to bring together researchers from all relevant fields to advance the state of the art in the research on generative episodic memory.
