Michael Brecht

Michael Brecht is a Professor at Humboldt University of Berlin, Faculty of Life Sciences, Department of Biology. His research focuses on neural mechanisms underlying somatosensory processing, memory consolidation, kinship behavior, and social play. He leads a research group investigating brain circuits related to these functions, with particular emphasis on the lateral septum, periaqueductal gray, and somatosensory cortex.

Professor Brecht's research interests include:

• Neural circuits for somatosensory processing and body map representation
• Mechanisms of memory consolidation from synapses to systems
• Neural basis of kinship behavior and social recognition
• Neurobiology of social play and vocal communication
• Spatial coding and navigation systems in the brain

His recent publications reveal a consistent focus on understanding how specific brain regions encode social and sensory information. Brecht's work frequently employs advanced techniques including electrophysiology, calcium imaging, optogenetics, and large-scale neural recording to investigate circuit mechanisms. A notable trend in his research is the investigation of sex differences in neural processing, particularly in genital somatosensory representation, and the identification of specialized neural architectures for social behaviors like kinship recognition.

Scientific contributions include:

• Discovery of nepotopy (topographical representation of kin/nonkin) in the lateral septum
• Demonstration of sex differences in genital cortex representation
• Identification of glycine-dependent mechanisms in social play behavior
• Mapping of vocalization-related activity in brainstem nuclei
• Elucidation of perirhinal input mechanisms for neocortical learning

Professor Brecht actively mentors students and collaborates with researchers across multiple institutions. His laboratory investigates both fundamental neural mechanisms and their implications for understanding social behavior. Current work appears focused on understanding the molecular and circuit-level basis of kinship memory and the neural substrates of social play behavior across development.
