Journal Article

Restoring continuous finger function with temporarily paralyzed nonhuman primates using brain–machine interfaces

Nason-Tomaszewski, Samuel R; Mender, Matthew J; Kennedy, Eric; Lambrecht, Joris M; Kilgore, Kevin L; Chiravuri, Srinivas; Ganesh Kumar, Nishant; Kung, Theodore A; Willsey, Matthew S; Chestek, Cynthia A; Patil, Parag G

2023 Journal of Neural Engineering

doi:10.1088/1741-2552/accf36 pmid:37084719

Objective. Brain–machine interfaces (BMIs) have shown promise in extracting upper extremity movement intention from the thoughts of nonhuman primates and people with tetraplegia. Attempts to restore a user’s own hand and arm function have employed functional electrical stimulation (FES), but most...

Micromagnetic stimulation (µMS) dose-response of the rat sciatic nerve

Saha, Renata; Sanger, Zachary; Bloom, Robert P; Benally, Onri J; Wu, Kai; Tonini, Denis; Low, Walter C; Keirstead, Susan A; Netoff, Theoden I; Wang, Jian-Ping

2023 Journal of Neural Engineering

doi:10.1088/1741-2552/acd582 pmid:37187172

Objective. The objective of this study was to investigate the effects of micromagnetic stimuli strength and frequency from the Magnetic Pen (MagPen) on the rat right sciatic nerve. The nerve’s response was measured by recording muscle activity and movement of the right hind limb. Approach. The...

Firing-rate-modulated spike detection and neural decoding co-design

Zhang, Zheng; Constandinou, Timothy G

2023 Journal of Neural Engineering

doi:10.1088/1741-2552/accece pmid:37080210

Objective. Translational efforts on spike-signal-based implantable brain-machine interfaces (BMIs) are increasingly aiming to minimise bandwidth while maintaining decoding performance. Developing these BMIs requires advances in neuroscience and electronic technology, as well as using...

Transcranial ultrasound stimulation relieves depression in mice with chronic restraint stress

Zhu, Yiyue; He, Jiaru; Wu, Canwen; Wu, Junwei; Cheng, Zhongwen; Chen, Yan; Yuan, Maodan; Zeng, Lvming; Ji, Xuanrong

2023 Journal of Neural Engineering

doi:10.1088/1741-2552/ac8bfd pmid:35998565

Objective. Exhaustion of Serotonin (5-hydroxytryptamine, 5-HT) is a typical cause of the depression disorder’s development and progression, including depression-like behaviors. Transcranial ultrasound stimulation (TUS) is an emerging non-invasive neuromodulation technique treating various...

Quantification of the robustness of functional neural networks: application to the characterization of Alzheimer’s disease continuum

Revilla-Vallejo, Marcos; Gómez, Carlos; Gomez-Pilar, Javier; Hornero, Roberto; Ángel Tola-Arribas, Miguel; Cano, Mónica; Shigihara, Yoshihito; Hoshi, Hideyuki; Poza, Jesús

2023 Journal of Neural Engineering

doi:10.1088/1741-2552/acd41c pmid:37164002

Objective. Brain connectivity networks are usually characterized in terms of properties coming from the complex network theory. Using new measures to summarize the attributes of functional connectivity networks can be an important step for their better understanding and characterization, as well...

Fiber-based optrode with microstructured fiber tips for controlled light delivery in optogenetics

Petrovic, Jelena; Lange, Fred; Hohlfeld, Dennis

2023 Journal of Neural Engineering

doi:10.1088/1741-2552/accecf pmid:37080213

Objective. Optogenetic modulation of neuronal activity requires precise and flexible light delivery to deep brain regions. Flat cleaved optical fibers combined with electrodes are widely used in implantable optogenetic devices for light delivery and electrical monitoring of neural activity....

Automated assembly of high-density carbon fiber electrode arrays for single unit electrophysiological recordings

Dong, Tianshu; Chen, Lei; Patel, Paras R; Richie, Julianna M; Chestek, Cynthia A; Shih, Albert J

2023 Journal of Neural Engineering

doi:10.1088/1741-2552/acd279 pmid:37141883

Objective. Carbon fiber (CF) is good for chronic neural recording due to the small diameter (7 µm), high Young’s modulus, and low electrical resistance, but most high-density carbon fiber (HDCF) arrays are manually assembled with labor-intensive procedures and limited by the accuracy and...

Journal Article

A fast blind source separation algorithm for decomposing ultrafast ultrasound images into spatiotemporal muscle unit kinematics

Rohlén, Robin; Lundsberg, Jonathan; Malesevic, Nebojsa; Antfolk, Christian

2023 Journal of Neural Engineering

doi:10.1088/1741-2552/acd4e9 pmid:37172576

Objective. Ultrasound can detect individual motor unit (MU) activity during voluntary isometric contractions based on their subtle axial displacements. The detection pipeline, currently performed offline, is based on displacement velocity images and identifying the subtle axial displacements....

Enhancement of EEG–EMG coupling detection using corticomuscular coherence with spatial–temporal optimization

Sun, Jingyao; Jia, Tianyu; Li, Zhibin; Li, Chong; Ji, Linhong

2023 Journal of Neural Engineering

doi:10.1088/1741-2552/accd9b pmid:37068482

Objective. Corticomuscular coherence (CMC) is widely used to detect and quantify the coupling between motor cortex and effector muscles. It is promisingly used in human–machine interaction (HMI) supported rehabilitation training to promote the closed-loop motor control for stroke patients....
