Improving neuroimaging methods
I have been involved
in a range of different projects associated with improving neuroimaging
methods. These include the following.
Work to improve
region-of-interest selection:
Brooks, J. L., Zoumpoulaki, A.,
& Bowman, H. (2017). Data‐driven region‐of‐interest selection without
inflating Type I error rate. Psychophysiology, 54(1),
100-113.
Bowman, H., Brooks, J. L.,
Hajilou, O., Zoumpoulaki, A., & Litvak, V. (2020). Breaking the Circularity
in Circular Analyses: Simulations and Formal Treatment of the Flattened Average
Approach. PLoS Computational Biology.
Work to highlight potential
problems of over-fitting hyper-parameters (over-hyping) in machine learning, as
applied in neuroimaging:
Hosseini, M., Powell, M., Collins,
J., Callahan-Flintoft, C., Jones, W., Bowman, H., & Wyble, B. (2020). I
tried a bunch of things: The dangers of unexpected overfitting in
classification of brain data. Neuroscience & Biobehavioral Reviews.
Work to highlight the problems of
small samples in neuroimaging:
Lorca-Puls, D. L., Gajardo-Vidal,
A., White, J., Seghier, M. L., Leff, A. P., Green, D. W., ... Bowman, H &
Price, C. J. (2018). The impact of sample size on the reproducibility of
voxel-based lesion-deficit mappings. Neuropsychologia, 115,
101-111.
Work to highlight problems
associated with use of bootstrapping in electrophysiology research:
Zoumpoulaki, A., Alsufyani, A.,
& Bowman, H. (2015). Resampling the peak, some dos and don'ts. Psychophysiology, 52(3),
444-448.
Work to develop more effective
methods to demonstrate latency differences between conditions:
Zoumpoulaki, A., Alsufyani, A.,
Filetti, M., Brammer, M., & Bowman, H. (2015). Latency as a region
contrast: Measuring ERP latency differences with dynamic time warping. Psychophysiology, 52(12),
1559-1576.
