Architected Lattices with a Topological Transition

Advanced Engineering Materials, EarlyView., 2023
This article develops topological metamaterials showing multidirectional two‐step deformation under compression by embedding contact‐enabled topological mechanisms into lattice structures. Experiments on 3D‐printed 2D and 3D lattices and finite element simulations are conducted to demonstrate the working principle of the topological metamaterials.

Velocity neurons improve performance more than goal or position neurons do in a simulated closed-loop BCI arm-reaching task.

Frontiers in Computational Neuroscience, 2015
Brain-Computer Interfaces (BCIs) that convert brain-recorded neural signals into intended movement commands could eventually be combined with Functional Electrical Stimulation to allow individuals with Spinal Cord Injury to regain effective and intuitive

A functional electrical stimulation system for human walking inspired by reflexive control principles [PDF]

, 2017
This study presents an innovative multichannel functional electrical stimulation gait-assist system which employs a well-established purely reflexive control algorithm, previously tested in a series of bipedal walking robots.

Searching for plasticity in dissociated cortical cultures on multi-electrode arrays [PDF]

, 2006
We attempted to induce functional plasticity in dense cultures of cortical cells using stimulation through extracellular electrodes embedded in the culture dish substrate (multi-electrode arrays, or MEAs). We looked for plasticity expressed in changes in

Use it or lose it: tonic activity of slow motoneurons promotes their survival and preferentially increases slow fiber-type groupings in muscles of old lifelong recreational sportsmen

European Journal of Translational Myology, 2016
Histochemistry, immuno-histochemistry, gel electrophoresis of single muscle fibers and electromyography of aging muscles and nerves suggest that: i) denervation contributes to muscle atrophy, ii) impaired mobility accelerates the process, and iii ...

Effects of electrical and optogenetic deep brain stimulation on synchronized oscillatory activity in Parkinsonian basal ganglia [PDF]

IEEE Trans Neural Syst Rehabil Eng 25:2188-2195, 2017, 2017
Conventional deep brain stimulation (DBS) of basal ganglia uses high-frequency regular electrical pulses to treat Parkinsonian motor symptoms and has a series of limitations. Relatively new and not yet clinically tested optogenetic stimulation is an effective experimental stimulation technique to affect pathological network dynamics.

Band power modulation through intracranial EEG stimulation and its cross-session consistency [PDF]

Journal of Neural Engineering, 17-054001 (2020), 2020
Background: Direct electrical stimulation of the brain through intracranial electrodes is currently used to probe the epileptic brain as part of pre-surgical evaluation, and it is also being considered for therapeutic treatments through neuromodulation.

Mobility test protocols for the elderly: a methodological note

European Journal of Translational Myology, 2015
Consequences of falls are a major health problem in elderly. Poor balance is the precursor of falls and balance impairment has been evidenced after an injury. On the other hand, balance and stability can be improved with training. At the beginning of the

Peripherical Electrical Stimulation for Parkinsonian Tremor: A Systematic Review

Frontiers in Aging Neuroscience, 2022
Parkinsonian tremor is one of the most common motor disorders in patients with Parkinson's disease (PD). Compared to oral medications and brain surgery, electrical stimulation approaches have emerged as effective and non-invasive methods for tremor ...
