Large-scale Recording from Axonal Arbors of Single Neurons with Cmos Based High-density Microelectrode Arrays
We report on the identification and tracking of the electrical activity of processes of single neurons. With a newly designed complementary metal-oxide-semiconductor (CMOS) based integrated highdensity microelectrode array (HD-MEA) [1,2], we were able to simultaneously use more than 1000 electrodes and low-noise readout channels to monitor electrophysiological signals of many individual branche...

متن کاملSingle-unit stability using chronically implanted multielectrode arrays.
The use of chronic intracortical multielectrode arrays has become increasingly prevalent in neurophysiological experiments. However, it is not obvious whether neuronal signals obtained over multiple recording sessions come from the same or different neurons. Here, we develop a criterion to assess single-unit stability by measuring the similarity of 1) average spike waveforms and 2) interspike i...
متن کاملTracking individual action potentials throughout mammalian axonal arbors
Axons are neuronal processes specialized for conduction of action potentials (APs). The timing and temporal precision of APs when they reach each of the synapses are fundamentally important for information processing in the brain. Due to small diameters of axons, direct recording of single AP transmission is challenging. Consequently, most knowledge about axonal conductance derives from modelin...
متن کاملAction potentials reliably invade axonal arbors of rat neocortical neurons.
Neocortical pyramidal neurons have extensive axonal arborizations that make thousands of synapses. Action potentials can invade these arbors and cause calcium influx that is required for neurotransmitter release and excitation of postsynaptic targets. Thus, the regulation of action potential invasion in axonal branches might shape the spread of excitation in cortical neural networks. To measure...
