Origins of 1/f2 scaling in the power spectrum of intracortical local field potential.

It has been noted that the power spectrum of intracortical local field potential (LFP) often scales as 1/f(-2). It is thought that LFP mostly represents the spiking-related neuronal activity such as synaptic currents and spikes in the vicinity of the recording electrode, but no 1/f(2) scaling is detected in the spike power. Although tissue filtering or modulation of spiking activity by UP and D...

The origins of 1/f scaling in the power spectrum of intra-cortical local field potential

It has been noted that the power spectrum of intra-cortical local field potential (LFP) often scales as 1/f. It is thought that LFP mostly represents the spikingrelated neuronal activity such as synaptic currents and spikes in the vicinity of the recording electrode but no 1/f scaling is detected in the spike power. Although tissue filtering or modulation of spiking activity by UP and DOWN stat...

A Multi-Channel Low-Power System-on-Chip for in vivo Neural Spike Recording

This paper reports a multi-channel neural spike recording system-on-chip (SoC) with digital data compression and wireless telemetry. The circuit consists of a 64-channel low-power low-noise analog front-end, a single 8-bit analog-todigital converter (ADC), followed by digital signal compression and transmission units. The 400-MHz transmitter employs a Manchester-Coded Frequency Shift Keying (MC...

A Multi-Channel Low-Power System-on-Chip for in Vivo Recording and Wireless Transmission of Neural Spikes

This paper reports a multi-channel neural spike recording system-on-chip with digital data compression and wireless telemetry. The circuit consists of 16 amplifiers, an analog time-division multiplexer, a single 8 bit analog-to-digital converter, a digital signal compression unit and a wireless transmitter. Although only 16 amplifiers are integrated in our current die version, the whole system ...
