general anaesthesia is feasible with the potential of
patient-individualised on-site brain-mapping of the
sensorimotor cortices for improved neuronavigation for
better functional outcomes and treatment monitoring.

3722. Brainstem
Functional Mapping During Motor Tasks with Ultra-High Field MRI
Y. Sun, D. Huang, L. Henderson, P. Austin, F. Calamante, Y.
Fu, J. Lv
University of Sydney, Sydney, Australia
Impact: Understanding brainstem motor function may
reveal early markers of Parkinson’s disease, bridging the
gap between molecular pathology and detectable brain
functional changes. This could advance early diagnosis and
deepen insights into PD-related neurodegeneration in motor
pathways.

3723. Functional
neural mechanisms and underlying structural changes are
associated with treatment efficacy in amblyopia
H. Singh, H. Gupta, R. Dhiman, S. S. Kumaran, R. Saxena
All India Institute of Medical Sciences, , New Delhi, India
Impact: By integrating imaging parameters and
identifying predictive factors for treatment response, it is
possible to develop more efficacious and individualized
treatment strategies for patients with amblyopia. The
functional-structural correlates observed in the study
suggest treatment response efficacy.

responses during stroop task correlates with glutamates and
gamma-aminobutyric acid at resting state
K. Ouchi, M. Fukunaga, T. Tsurugizawa
National Institute of Advanced Industrial Science and Technology (AIST), Ibaraki, Japan
Impact: This study reveals that the concentration of
Glu/GABA at resting state have a impact on brain activity
related to cognitive task, suggesting that these neural
metabolites could be useful as biomarkers for cognitive
function.

3725. Adaptive
approach for task fMRI group-level activation detection
X. Zhuang, Z. Yang, M. Lowe, D. Cordes
Cleveland Clinic Nevada, Las Vegas, United States
Impact: Improve the sensitivity and specificity of
task-fMRI group-level activation detection.

3726. Multimodal
characterization of inter-individual differences during auditory
statistical learning
J. Miehlbradt, D. Romascano, J. Wirsich, F. Grouiller, P.
Hüppi
University of Geneva, Geneva, Switzerland
Impact: We show that BOLD variability and EEG
entrainment are appropriate markers to assess
learning-specific brain activity patterns. In addition,
outcomes from these distinct imaging modalities present
similarities in spatial localization and explainability of
behavioral outcomes.

3728. Comparing
Activation-Induced Changes in Cerebral Oxygen Metabolism
Measured by Calibrated fMRI and [15O]O2-PET
G. Deller, L. Liu, L. Narciso, J. Hicks, M. Langham, F.
Wehrli, K. St. Lawrence
Lawson Health Research Institute, London, Canada
Impact: This study is the first direct comparison of
c-fMRI to [15O]O2-PET and demonstrated the accuracy of the
MRI method.

3729. Near-silent
Looping Star fMRI during a passive listening task: preliminary
results
C. Ritter, A. Hüsser, A. Jakab, F. Wiesinger, B. Fernandez,
A. Solana, R. O´Gorman-Tuura, A. Hervais-Adelman
University of Geneva, Geneva, Switzerland
Impact: : LS may be a valid alternative for future
research utilizing auditory stimuli without the added
confound of background noise and the risk of adverse health
effects. The sequence might also be specifically suitable to
research sound averse populations.

3730. Assessing
diffusion changes in response to visual stimulation: A
multi-directional MPG approach in diffusion fMRI
I. KIDA
National Institute of Information and Communications Technology, Suita, Japan
Impact: dfMRI with multiple MPG directions enables more
localized brain activity mapping compared to BOLD-fMRI,
suggesting that water transport related to neuronal activity
may contribute to pseudo-diffusion effects in diffusion MRI
signals.

3731. Hemodynamic
activity in the putamen during motor-observation: initial
volunteers’ study with multi-echo EPI at 7 T
G. Baz, R. Schmidt
Weizmann institute of science, Rehovot, Israel
Impact: Functional MRI studies have shown mixed results
regarding whether the basal ganglia is active during motor
observation. Using a small cohort of subjects, we
demonstrate that motor observation does elicit a visible
hemodynamic response. Pronounced individual differences
invite further research.

3732. Brainstem
activation from sustained vowel phonation
H. Cheng, S. Brink, C. Smith, D. AAlto, S. Lulich
Indiana University, Bloomington, United States
Impact: Our results demonstrate the feasibility of
localizing brainstem nucleus with fast simultaneous
multi-slice EPI and sustained vowel phonation tasks.

Impact: A comprehensive comparison of Multi-Echo fMRI
with an Optimized Single-Echo (OSE) acquisition (i.e. not
with data derived from ME itself) enables a direct
evaluation of two different acquisition approaches at their
best performances.
