Iotzov I, Parra L
Eur J Neurosci
. 2025 Feb;
61(3):e70009.
PMID: 39939282
Speech is hard to understand when there is background noise. Speech intelligibility and listening effort both affect our ability to understand speech, but the relative contribution of these factors is...

bioRxiv
. 2025 Jan;
PMID: 39868267
Electric fields used in clinical trials with transcranial direct current stimulation (tDCS) are small, with magnitudes that have yet to demonstrate measurable effects in preclinical animal models. We hypothesized that...

PLoS One
. 2025 Jan;
20(1):e0313875.
PMID: 39787085
Complex systems, such as in brains, markets, and societies, exhibit internal dynamics influenced by external factors. Disentangling delayed external effects from internal dynamics within these systems is often difficult. We...

Zareen N, Yung H, Kaczetow W, Glattstein A, Mazalkova E, Alexander H, et al.
Proc Natl Acad Sci U S A
. 2024 Nov;
121(47):e2408508121.
PMID: 39536089
Electrical motor cortex stimulation can produce corticospinal system plasticity and enhance motor function after injury. We investigate molecular mechanisms of structural and physiological plasticity following electrical neuromodulation, focusing on identifying...

Hirsch L, Huang Y, Makse H, Martinez D, Hughes M, Eskreis-Winkler S, et al.
Acad Radiol
. 2024 Oct;
32(3):1218-1225.
PMID: 39482209
Rationale And Objectives: To develop and evaluate an AI algorithm that detects breast cancer in MRI scans up to one year before radiologists typically identify it, potentially enhancing early detection...

bioRxiv
. 2024 Oct;
PMID: 39463938
Sensory stimulation of the brain reverberates in its recurrent neuronal networks. However, current computational models of brain activity do not separate immediate sensory responses from intrinsic recurrent dynamics. We apply...

Huang Y, Leotta N, Hirsch L, Gullo R, Hughes M, Reiner J, et al.
J Imaging Inform Med
. 2024 Sep;
PMID: 39320547
This work aims to perform a cross-site validation of automated segmentation for breast cancers in MRI and to compare the performance to radiologists. A three-dimensional (3D) U-Net was trained to...

Farahani F, Khadka N, Parra L, Bikson M, Voroslakos M
Brain Stimul
. 2024 Apr;
17(3):561-571.
PMID: 38631548
Background: Notwithstanding advances with low-intensity transcranial electrical stimulation (tES), there remain questions about the efficacy of clinically realistic electric fields on neuronal function. Objective: To measure electric fields magnitude and...

Cell Rep
. 2024 Apr;
43(4):114081.
PMID: 38581682
Narratives can synchronize neural and physiological signals between individuals, but the relationship between these signals, and the underlying mechanism, is unclear. We hypothesized a top-down effect of cognition on arousal...

J Imaging Inform Med
. 2024 Feb;
37(2):536-546.
PMID: 38343223
Deep neural networks have demonstrated promising performance in screening mammography with recent studies reporting performance at or above the level of trained radiologists on internal datasets. However, it remains unclear...
