In another leap for neuroscience and assistive technology, Elon Musk’s Neuralink has achieved another milestone. Noland Arbaugh, a 29-year-old paralyzed in a diving accident, has become the first person to send a tweet using only his thoughts, thanks to Neuralink’s innovative brain implant.
Activity-dependent spinal cord neuromodulation rapidly restores trunk and leg motor functions after complete paralysis www.nature.com March 4, 2024, 10:38 a.m.
Epidural electrical stimulation (EES) targeting the dorsal roots of lumbosacral segments restores walking in people with spinal cord injury (SCI). However, EES is delivered with multielectrode paddle leads that were originally designed to target the dorsal column of the spinal cord. Here, we hypothesized that an arrangement of electrodes targeting the ensemble of dorsal roots involved in leg and trunk movements would result in superior efficacy, restoring more diverse motor activities after the most severe SCI. To test this hypothesis, we established a computational framework that informed the optimal arrangement of electrodes on a new paddle lead and guided its neurosurgical positioning.

Invasive electroencephalography monitoring: Indications and presurgical planning www.ncbi.nlm.nih.gov March 1, 2024, 7:51 p.m.
Electroencephalography (EEG) remains a “gold standard” for defining seizures; hence identification of epileptogenic zone for surgical treatment of epilepsy requires precise electrographic localization of the seizures. Routine scalp EEG recording is not sufficient in many instances, such as extratemporal lobe epilepsy or non-lesional temporal lobe epilepsy. In these individuals EEG recording from proximity of the seizure focus is necessary, which can be achieved by placing electrodes on the surface or in the substance of the brain. As this process requires invasive procedures (usually necessitating surgical intervention) EEG obtained via these electrodes is defined as invasive electroencephalography (iEEG). As only limited areas of the brain can be covered by these electrodes in an individual, precise targeting of the presumed seizure onset location is crucial.
Vagus Nerve Stimulation (VNS) Therapy epilepsysociety.org.uk March 1, 2024, 7:48 p.m.
Vagus Nerve Stimulation therapy is a treatment for epilepsy that involves a stimulator (or 'pulse generator') which is connected, inside the body, to the left vagus nerve in the neck. The stimulator sends regular, mild electrical stimulations through this nerve to help calm down the irregular electrical brain activity that leads to seizures.
Deep brain stimulation - Mayo Clinic www.mayoclinic.org March 1, 2024, 7:46 p.m.
Deep brain stimulation (DBS) involves implanting electrodes within areas of the brain. The electrodes produce electrical impulses that affect brain activity to treat certain medical conditions. The electrical impulses also can affect cells and chemicals within the brain that cause medical conditions. The amount of stimulation in deep brain stimulation is controlled by a pacemaker-like device placed under the skin in the upper chest. A wire that travels under the skin connects this device to the electrodes in the brain.
Parkinson's Disease (PD) mayfieldclinic.com March 1, 2024, 7:44 p.m.
Parkinson’s disease (PD) is a progressive disorder that affects nerve cells in the brain responsible for body movement. When dopamine-producing neurons die, symptoms such as tremor, slowness, stiffness, and balance problems occur. Treatments focus on reducing symptoms to enable a more active lifestyle and include medication, diet, exercise, and deep brain stimulation surgery.
The Anatomical Basis of Seizures - Epilepsy www.ncbi.nlm.nih.gov March 1, 2024, 7:44 p.m.
Paroxysmal alteration of neurological function caused by an excessive hypersynchronous neuronal discharge in the brain is known as seizure. Non-epileptic seizure is short-lived while epilepsy is a neurological condition characterized by two or more provoked seizures. The hippocampus, amygdala, frontal cortex, temporal cortex, and olfactory cortex are the common areas involved in seizures. According to the ‘dormant basket cell’ theory, loss of excitatory input from the dentate mossy cells makes inhibitory basket cells dormant while according to the ‘mossy fiber’ theory, mossy fibers induce the formation of excitatory circuits resulting in hyperexcitability.
A Comparative Study of Machine Learning Algorithms for EEG Signal Classification fr.slideshare.net Feb. 25, 2024, 9:19 p.m.
The best classification accuracy achieved was 70.4% with SVM through featureengineering. However, our prosed method of autoencoder in combination with SVM produced a similaraccuracy of 65% without using any feature engineering technique. This research shows that this system ofclassification of motor movements can be used in a Brain-Computer Interface system (BCI) to mentallycontrol a robotic device or an exoskeleton.
Evaluation of Machine Learning Algorithms for Classification of EEG Signals www.mdpi.com Feb. 25, 2024, 9:17 p.m.
The model of Medium-ANN achieved the best performance metrics, with an AUC average of 0.9998, Cohen’s Kappa coefficient of 0.9552, Matthews correlation coefficient of 0.9819, and loss of 0.0147. These findings enable the approach to be applied to different scenarios, such as robotic prosthesis implementation, where the utilization of physical qualities is an acceptable alternative when hardware resources are restricted, or in embedded systems or edge computing devices, which have the advantages of low cost, small size, portability, low power consumption, and reliable communication with the BCI.
The Computer Of the Future Might Be In Your Head www.techtimes.com Feb. 25, 2024, 9:12 p.m.
"The debate between headsets and implants as the computer of the future is fascinating, with significant developments on both fronts," Matthew Price, Founder and Editor at Maccidents. But considering both technologies' current states and potential, Price believes headsets are more likely to become the computer of the future, at least for the general populace. That's because they offer advanced interaction without the ethical and health implications of a brain surgery one would need to undergo to get an implant.

Endovascular Brain-Computer Interface Safe, Effective in ALS www.medpagetoday.com Feb. 17, 2024, 10:32 a.m.
"The sensors are positioned on a stent-like scaffold that deploys against the walls of the superior sagittal sinus, which is a large blood vessel that runs adjacent to the medial edge of the primary motor cortex," Weber said. "This device senses the electrical activity that occurs in the motor cortex when someone thinks about moving their limbs."
Ethical Considerations of Endovascular Brain–Computer Interfaces link.springer.com Feb. 17, 2024, 10:30 a.m.
The use of stent-based endovascular electrode arrays is a recent approach to brain–computer interfaces (BCIs). These arrays can record neuronal activity from within the large blood vessels of the brain following placement via catheterization. Accessing the brain without the need for open craniotomy is appealing and may inspire future generations of endovascular BCI devices. Here we review some of the bioethical considerations arising from the adoption of endovascular electrode arrays for BCIs.
Intracortical Brain–Machine Interfaces link.springer.com Feb. 17, 2024, 10:29 a.m.
A brain–machine interface, or BMI, directly connects the brain to the external world, bypassing damaged biological pathways. It replaces the impaired parts of the nervous system with hardware and software that translate a user’s internal motor commands into action. In this chapter, we will discuss the four basic components of an intracortical BMI: an intracortical neural recording, a decoding algorithm, an output device, and sensory feedback.
