On-chip seizure detectors that learn on their own

Adelson Chua and Rikky Muller Department of Electrical Engineering and Computer Sciences at the University of California, Berkeley Epilepsy affects about 50 million people worldwide and is characterized by recurring seizures that can lead to involuntary movements, loss of consciousness, and even death. Several technology-based solutions for monitoring and treating epilepsy have emerged in recent years involving wearable and implantable …

Direct-Digitization Neural Readouts for Fully-Integrated and High-Density Neural Recording

Monitoring large groups of neurons in various brain regions, including superficial and deep structures, is crucial for advancing neuroscience research on cognition, motor control, behavior, among other areas [1], [2]. Current extracellular CMOS high-density neural probes are becoming the new standard in electrophysiology, allowing for simultaneous recording with excellent spatial and temporal resolution [3]–[5]. However, there is still a demand for neural recording technologies that can access a significantly larger number of neurons, allowing for the decoding of more complex motor, sensory, and cognitive tasks. To achieve this, it is necessary to develop neural probes with much higher number of channels, which requires the design of readout circuits that meet several requirements, including: i) area- and power-efficiency, ii) low noise to capture weak neural signals, iii) capability to interface with large-impedance and high-DC-offset electrodes, and iv) tolerance to artifacts caused by movement or concurrent electrical stimulation.

Legal Preamble

Legal System Preamble Since ancient times, various tools have been used across different cultures in order to mete out justice—starting with infusions, poisons, and mystical foods, such as the interrogations using “truth drugs” and the trance state in oracles from Delphi to Tibet and Shamanic cultures. Efforts to understand criminal behavior, assess states of mind, and apply interventions to modify …

Entertainment Preamble

Entertainment Preamble The field of entertainment has consistently made use of advances in technology to hold the attention and interest of an audience, to convey emotion and information, and typically to provide amusement. From the innovations of props, sets, dance, sound, music, and video that are conveyed in person, pre-recorded, or transmitted great distances, efforts to incorporate neurotechnology into entertainment …

Sports & Competitions Preamble

Sports & Competitions Preamble Sport—testing one’s abilities, talent, dedication, and performance in fair competition—differs in meaning and execution for everyone. The competition may be head-to-head against others, against a benchmark, or against one’s own self; it could happen in a driveway, in a basement, or in an Olympic stadium. Sometimes the competition is a test of physiology, sometimes a test …

Military and National Security Preamble

Military and National Security Preamble Attempts by the military to modulate the brain to optimize mental and physical performance are not novel. Increasingly, as multi-domain operations become more complex, requirements placed on decision-making, situational awareness, ability, and mental and physical performance only continues to expand. Military service members also face unique situational challenges, often including hazardous situations that can be …

Work & Employment Preamble

Work and Employment Preamble Much of life in modern society is organized by relations of work. Neurotechnology has the potential to change how we think about the meaning of work as well as the definition of the workplace. Some neurotechnologies may extend the work-day, blurring the distinction between work and leisure time. The same could be true for the ‘place’ …
