Signal properties and stability of a chronically implanted endovascular brain computer interface Open
Background Implanted brain-computer interfaces (iBCIs) establish direct communication with the brain and hold the potential to enable people with severe disability to achieve control of digital devices, enabling communication and digital a…

QFT: Post-training quantization via fast joint finetuning of all degrees of freedom Open
The post-training quantization (PTQ) challenge of bringing quantized neural net accuracy close to original has drawn much attention driven by industry demand. Many of the methods emphasize optimization of a specific degree-of-freedom (DoF)…

Detecting Spontaneous Neural Oscillation Events in Primate Auditory Cortex Open
Electrophysiological oscillations in the brain have been shown to occur as multicycle events, with onset and offset dependent on behavioral and cognitive state. To provide a baseline for state-related and task-related events, we quantified…

Oscillatory Bursting as a Mechanism for Temporal Coupling and Information Coding Open
Even the simplest cognitive processes involve interactions between cortical regions. To study these processes, we usually rely on averaging across several repetitions of a task or across long segments of data to reach a statistically valid…

Dissociation of broadband high-frequency activity and neuronal firing in the neocortex Open
BHA (aka high gamma) correlates with neuronal firing, but is generated mainly by dendritic processes separable from firing.

Does the phase of ongoing EEG oscillations predict auditory perception? Open
Summary Effective processing of information from the environment requires the brain to selectively sample relevant inputs. The visual perceptual system has been shown to sample information rhythmically, oscillating rapidly between more and…

Electrophysiological oscillations in the brain have been shown to occur as multi-cycle events, with onset and offset dependent on behavioral and cognitive state. To provide a baseline for state-related and task-related events, we quantifie…

Dissociation of broadband high-frequency activity and neuronal firing in the neocortex Open
Broadband High-frequency Activity (BHA; 70-150 Hz), also known as "high gamma," a key analytic signal in human intracranial recordings is often assumed to reflect local neural firing (multiunit activity; MUA). Accordingly, BHA has been use…

Decoding multimodal behavior using time differences of MEG events Open
Multimodal behavior involves multiple processing stations distributed across distant brain regions, but our understanding of how such distributed processing is coordinated in the brain is limited. Here we take a decoding approach to this p…

Neural Entrainment to the Beat: The “Missing-Pulse” Phenomenon Open
Most humans have a near-automatic inclination to tap, clap, or move to the beat of music. The capacity to extract a periodic beat from a complex musical segment is remarkable, as it requires abstraction from the temporal structure of the s…

Temporal accuracy of human cortico-cortical interactions Open
The precision in space and time of interactions among multiple cortical sites was evaluated by examining repeating precise spatiotemporal patterns of instances in which cortical currents showed brief amplitude undulations. The amplitudes o…
