Two nonhuman primate subjects performed over 26,500 self-paced reaches to grid targets while neural activity was recorded from up to 192 channels in M1 and S1 cortex. Data includes threshold crossing times of sorted spikes and fingertip/target positions at 250 Hz, collected from 47 sessions spanning about 11 months. The dataset was contributed by Joseph E. O’Doherty and is hosted on Papers with Code.
Use Cases
- Training continuous BCI decoders based on unsorted, trial-free neural spiking and kinematic data.
- Modeling sensorimotor cortical spiking activity based on simultaneous recordings from M1 and S1 arrays.
- Analyzing the statistics of arm kinematics based on fingertip and target position time series.
- Studying spike noise-correlations or signal-correlations across up to 192 recording channels.
- Exploring the long-term stability of extracellular recordings over sessions spanning months.
Strengths
- Includes data from 47 recording sessions across two monkeys, totaling approximately 26,500 reaches.
- Contains high-temporal-resolution (250 Hz) fingertip and target position data alongside sorted neural spike times.
- Recordings were made from up to 192 channels, covering both primary motor (M1) and somatosensory (S1) cortex in some sessions.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count, file formats, and exact data size are unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
