Schumann A, Uhde T, Houghton D, Yang Q, Cortese B
Neuroimage . 2025 Feb; 309:121072. PMID: 39929406
Significant differences in the independent processing of trauma-related visual or olfactory cues have been demonstrated in posttraumatic stress disorder (PTSD). Yet, it remains unclear if PTSD-related differences exist in how...

Cortese B, Uhde T, Schumann A, McTeague L, Sege C, Calhoun C, et al.
Chem Senses . 2021 Dec; 46. PMID: 34958383
Anxious adults show changes in smell function that are consistent with a durable shift in sensitivity toward particular odorants and away from others. Little is known regarding the development of...

Cortese B, Schumann A, Howell A, McConnell P, Yang Q, Uhde T
Neuroimage Clin . 2017 Nov; 17:378-387. PMID: 29159050
Structural and functional changes in the olfactory system are increasingly implicated in the expression of PTSD. Still, very little is known about the neurobiological networks of trauma-related odor sensitivity or...

Kuhnhold A, Schumann A, Bartsch R, Ubrich R, Barthel P, Schmidt G, et al.
Physiol Meas . 2017 Feb; 38(5):925-939. PMID: 28151433
Objective: Phase synchronization between two weakly coupled oscillators occurs in many natural systems. Since it is difficult to unambiguously detect such synchronization in experimental data, several methods have been proposed...

Bartsch R, Schumann A, Kantelhardt J, Penzel T, Ivanov P
Proc Natl Acad Sci U S A . 2012 Jun; 109(26):10181-6. PMID: 22691492
Integrated physiological systems, such as the cardiac and the respiratory system, exhibit complex dynamics that are further influenced by intrinsic feedback mechanisms controlling their interaction. To probe how the cardiac...

Schumann A, Bartsch R, Penzel T, Ivanov P, Kantelhardt J
Sleep . 2010 Jul; 33(7):943-55. PMID: 20614854
Study Objectives: Respiratory and heart rate variability exhibit fractal scaling behavior on certain time scales. We studied the short-term and long-term correlation properties of heartbeat and breathing-interval data from disease-free...

Gans F, Schumann A, Kantelhardt J, Penzel T, Fietze I
Phys Rev Lett . 2009 Apr; 102(9):098701. PMID: 19392568
The dynamics of complex systems is characterized by oscillatory components on many time scales. To study the interactions between these components we analyze the cross modulation of their instantaneous amplitudes...

Hamann C, Bartsch R, Schumann A, Penzel T, Havlin S, Kantelhardt J
Chaos . 2009 Apr; 19(1):015106. PMID: 19335010
Phase synchronization between two weakly coupled oscillators has been studied in chaotic systems for a long time. However, it is difficult to unambiguously detect such synchronization in experimental data from...

Kantelhardt J, Bauer A, Schumann A, Barthel P, Schneider R, Malik M, et al.
Chaos . 2007 Apr; 17(1):015112. PMID: 17411269
We present the phase-rectified signal averaging (PRSA) method as an efficient technique for the study of quasi-periodic oscillations in noisy, nonstationary signals. It allows the assessment of system dynamics despite...
