Gusman J, Hosman T, Crawford R, Singer-Clark T, Kapitonava A, Kelemen J, et al.
J Neural Eng . 2025 Feb; PMID: 39899980
Objective: Intracortical brain-computer interfaces (iBCIs) have demonstrated the ability to enable point and click as well as reach and grasp control for people with tetraplegia. However, few studies have investigated...

Shah N, Avansino D, Kamdar F, Nicolas C, Kapitonava A, Vargas-Irwin C, et al.
bioRxiv . 2023 Oct; PMID: 37873182
How does the motor cortex combine simple movements (such as single finger flexion/extension) into complex movements (such hand gestures or playing piano)? Motor cortical activity was recorded using intracortical multi-electrode...

Rule M, Vargas-Irwin C, Donoghue J, Truccolo W
J Neurophysiol . 2018 Feb; 119(6):2212-2228. PMID: 29442553
Previous studies on the origin and properties of spatial patterns in motor cortex β-local field potential (β-LFP) oscillations have focused on planar traveling waves. However, it is unclear 1) whether...

Rule M, Vargas-Irwin C, Donoghue J, Truccolo W
Front Syst Neurosci . 2015 Jul; 9:89. PMID: 26157365
Understanding the sources of variability in single-neuron spiking responses is an important open problem for the theory of neural coding. This variability is thought to result primarily from spontaneous collective...

Barrese J, Rao N, Paroo K, Triebwasser C, Vargas-Irwin C, Franquemont L, et al.
J Neural Eng . 2013 Nov; 10(6):066014. PMID: 24216311
Objective: Brain-computer interfaces (BCIs) using chronically implanted intracortical microelectrode arrays (MEAs) have the potential to restore lost function to people with disabilities if they work reliably for years. Current sensors...

Zhuang J, Truccolo W, Vargas-Irwin C, Donoghue J
Annu Int Conf IEEE Eng Med Biol Soc . 2010 Nov; 2010:4347-50. PMID: 21096002
Recent developments in neural interface systems hold the promise to restore movement in people with paralysis. In search of neural signals for control of neural interface systems, previous studies have...

Zhuang J, Truccolo W, Vargas-Irwin C, Donoghue J
IEEE Trans Biomed Eng . 2010 Apr; 57(7):1774-84. PMID: 20403782
Intracortical microelectrode array recordings generate a variety of neural signals with potential application as control signals in neural interface systems. Previous studies have focused on single and multiunit activity (MUA),...

Vargas-Irwin C, Donoghue J
J Neurosci Methods . 2007 May; 164(1):1-18. PMID: 17512603
In multiple cell recordings identifying the number of neurons and assigning each action potential to a particular source, commonly referred to as 'spike sorting', is a highly non-trivial problem. Density...

Suner S, Fellows M, Vargas-Irwin C, Nakata G, Donoghue J
IEEE Trans Neural Syst Rehabil Eng . 2006 Jan; 13(4):524-41. PMID: 16425835
Multiple-electrode arrays are valuable both as a research tool and as a sensor for neuromotor prosthetic devices, which could potentially restore voluntary motion and functional independence to paralyzed humans. Long-term...

Wood F, Black M, Vargas-Irwin C, Fellows M, Donoghue J
IEEE Trans Biomed Eng . 2004 Jun; 51(6):912-8. PMID: 15188858
The analysis of action potentials, or "spikes," is central to systems neuroscience research. Spikes are typically identified from raw waveforms manually for off-line analysis or automatically by human-configured algorithms for...
