We present a new single channel in-line setup for holographic recording that can properly record various objects that cannot be recorded by the Gabor holographic method. This configuration allows the recording of holograms based on several modalities while addressing important issues of the original Gabor setup, including the well-known twin-image problem and the weak scattering condition.

Following the trend of turbo codes and low density parity check (LDPC) codes, single-parity turbo product codes (TPC/SPC) are being seriously considered for application in future high-density recording systems. Recent work on TPC/SPC codes has focused on ideal partial response channels with additive white Gaussian noise. This work extends the investigation to a more realistic equalized Lorentzi...

HIS paper presents measurement results of 8-channel integrated circuit dedicated to recording and detection of a broad range of biomedical signals. The aim of our work is to develop an implementable multichannel system comprising of hundreds of recording electrodes combined with integrated electronics. The main requirements of such systems are: low power consumption (<10 μW), area occupation (<...

A new generation of nerve cuffs suitable for stimulation, recording and modulation of nerve activity has been tested in our laboratory and elsewhere. The walls are molded of low-durometer silicone and incorporate flexible electrodes, Teflon-coated stainless steel leads and an interlocking opening/closing system. Stimulation and recording cuffs can be either single-channel or multichannel. Singl...

How does one part affect another in the brain? How much information can we extract from the brain data? The multichannel EEG recording system is now available to study this issue. We recorded 256-channel EEGs while a subject performed a visual discrimination task, and obtained mutual information between a visual stimulus condition and signals from single and multiple EEGs. Here we report prelim...

this study has examined the functional importance of nucleus accumbens (nac)-ventral tegmental area (vta) interactions. as it is known, this interaction is important in associative reward processes. under urethane anesthesia, extracellular single unit recordings of the shell sub-region of the nucleus accumbens (nacsh) neurons were employed to determine the functional contributions of the vta to...
