Journal article Journal of neurophysiology · September 2014 Featured Publication Our understanding of the large-scale population dynamics of neural activity is limited, in part, by our inability to record simultaneously from large regions of the cortex. Here, we validated the use of a large-scale active microelectrode array that simult ... Full text Cite

A low-cost, multiplexed electrophysiology system for chronic μECoG recordings in rodents.

Journal article Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference · January 2014 Featured Publication Micro-Electrocorticography (μECoG) offers a minimally invasive, high resolution interface with large areas of cortex. However, large arrays of electrodes with many contacts that are individually wired to external recording systems are cumbersome and make c ... Full text Cite

A low-cost, open-source, wireless electrophysiology system.

Journal article Annual International Conference of the IEEE Engineering in Medicine and Biology Society. IEEE Engineering in Medicine and Biology Society. Annual International Conference · January 2014 Featured Publication Many experiments in neuroscience require or would benefit tremendously from a wireless neural recording system. However, commercially available wireless systems are expensive, have moderate to high noise and are often not customizable. Academic wireless sy ... Full text Cite

Flexible, foldable, actively multiplexed, high-density electrode array for mapping brain activity in vivo.

Journal article Nature neuroscience · November 2011 Featured Publication Arrays of electrodes for recording and stimulating the brain are used throughout clinical medicine and basic neuroscience research, yet are unable to sample large areas of the brain while maintaining high spatial resolution because of the need to individua ...

Data mining neocortical high-frequency oscillations in epilepsy and controls.

Journal article Brain : a journal of neurology · October 2011 Featured Publication Transient high-frequency (100-500 Hz) oscillations of the local field potential have been studied extensively in human mesial temporal lobe. Previous studies report that both ripple (100-250 Hz) and fast ripple (250-500 Hz) oscillations are increased in th ... Full text Cite

Materials for multifunctional balloon catheters with capabilities in cardiac electrophysiological mapping and ablation therapy.

Journal article Nature materials · April 2011 Featured Publication Developing advanced surgical tools for minimally invasive procedures represents an activity of central importance to improving human health. A key challenge is in establishing biocompatible interfaces between the classes of semiconductor device and sensor ... Full text Cite

Unsupervised classification of high-frequency oscillations in human neocortical epilepsy and control patients.

Journal article Journal of neurophysiology · November 2010 Featured Publication High-frequency oscillations (HFOs) have been observed in animal and human intracranial recordings during both normal and aberrant brain states. It has been proposed that the relationship between subclasses of these oscillations can be used to identify epil ... Full text Cite

Dissolvable films of silk fibroin for ultrathin conformal bio-integrated electronics.

Journal article Nature materials · June 2010 Featured Publication Electronics that are capable of intimate, non-invasive integration with the soft, curvilinear surfaces of biological tissues offer important opportunities for diagnosing and treating disease and for improving brain/machine interfaces. This article describe ... Full text Cite

A conformal, bio-interfaced class of silicon electronics for mapping cardiac electrophysiology.

Journal article Science translational medicine · March 2010 Featured Publication In all current implantable medical devices such as pacemakers, deep brain stimulators, and epilepsy treatment devices, each electrode is independently connected to separate control systems. The ability of these devices to sample and stimulate tissues is hi ... Full text Cite
