Functional imaging of hippocampal place cells at cellular resolution during virtual navigation (2010, neutral): “While sub-millisecond temporal resolution is a major advantage of this method compared to imaging, the current limitations of tetrode methods are the low spatial resolution (>100s of microns) and sparse sampling within the micro-circuitry 38 , 40 .”
The neural basis of the blood-oxygen-level-dependent functional magnetic resonance imaging signal. (2002, background): “Recent simultaneous intracellular and extracellular tetrode recordings from single neurons showed that the amplitude of the average extracellular spike decreases rapidly as a function of the distance of the tip from the soma, with the largest amplitudes recorded at distances smaller than 50 m; at di”
Behavioral correlates of activity in identified hypocretin/orexin neurons. (2005, positive): “Therefore, we used the LPD as a more stable parameter that reflects the duration of the intracellular afterhyperpolarization phase (Henze et al., 2000), which is important for identification of Hcrt cells, and the total width of hypothalamic cell spikes.”
Sparse Representation of Sounds in the Unanesthetized Auditory Cortex (2008, background): “GABAergic interneurons [33,46]) to have narrow and symmetrical spikes due to the fast repolarization [33,46,47].”
A spike sorting toolbox for up to thousands of electrodes validated with ground truth recordings in vitro and in vivo (2018, background): “Ground truth data recorded in vivo are scarce (Henze et al., 2000; Neto et al., 2016) and in many cases the patch-recorded neuron is relatively far from the extracellular electrodes.”
Challenges and opportunities for large-scale electrophysiology with Neuropixels probes (2018, methodology): “The best form of ground truth, then, is actual simultaneous recording of spikes with another method such as a juxtacellular electrode [49 ,50].”
Direct activation of sparse, distributed populations of cortical neurons by electrical microstimulation. (2009, background): “Extracellular recording mainly reveals large current flows (Johnston and Wu, 1994; Henze et al., 2000) coming from the somata of neurons near the electrode.”
Differential attention-dependent response modulation across cell classes in macaque visual area V4. (2007, background): “The duration of the extracellular spike waveform is directly related to the duration of the intracellular waveform (Henze et al., 2000; Gold et al., 2006).”
Place cells, grid cells, and the brain's spatial representation system. (2008, background): “More than 35 years ago, O’Keefe & Dostrovsky (1971) reported spatial receptive fields in complex-spiking neurons in the rat hippocampus, which are likely to be pyramidal cells (Henze et al. 2000).”
The Underpinnings of the BOLD Functional Magnetic Resonance Imaging Signal (2003, background): “, 1994), single-electrode recordings could provide information concerning the activity of 1000 neurons (Henze et al., 2000).”
Neuronal cell loss accompanies the brain tissue response to chronically implanted silicon microelectrode arrays. (2005, background): “Reductions in resolving capability of single units were encountered when recording beyond this distance (Henze et al., 2000).”
Response of brain tissue to chronically implanted neural electrodes. (2005, background): “Direct measure ents suggest however, that the maximum distance is muc omewhere between 50 and 100 m (Mountcastle, 1957; Ra 962; Rosenthal, 1972; Henze et al., 2000).”
Sparse Representation in the Human Medial Temporal Lobe (2006, methodology): “…radius of an extracellular electrode are entirely silent during a recording session (e.g., there are as many as 120 –140 neurons within the sampling region of a tetrode in the CA1 region of the hippocampus (Henze et al., 2000), but we typically only succeed in identifying 1–5 units per electrode).”
