In order to extract neural information, action potentials recorded with cuff electrodes from peripheral nerves were classified into unit activities. The classification was performed based on their waveforms, as it was considered that they were affected by the radius of nerve fiber and the distance between fiber and recording electrode. This study focused on automatic classification method. Acti...

Cortical neurons have been reported to use both rate and temporal codes. Here we describe a novel mode in which each neuron generates exactly 0 or 1 action potentials, but not more, in response to a stimulus. We used cell-attached recording, which ensured single-unit isolation, to record responses in rat auditory cortex to brief tone pips. Surprisingly, the majority of neurons exhibited binary ...

Elevated sympathetic activation is a characteristic feature of heart failure (HF). Excessive sympathetic activation under resting conditions has been shown to increase from the early stages of the disease, and is related to prognosis. Direct recording of multiunit efferent muscle sympathetic nerve activity (MSNA) by microneurography is the best method for quantifying sympathetic nerve activity ...

Electrode arrays interfacing with peripheral nerves are essential for neuromodulation devices targeting peripheral organs to relieve symptoms. To modulate (i.e., single-unit recording and stimulating) individual peripheral nerve axons remains a technical challenge. Here, we report an in vitro setup to allow simultaneous single-unit recordings from multiple mouse sciatic nerve axons. The sciatic...

A technique is described which allows recording of multi-fiber discharge and single-unit activity from intact peripheral nerves of awake human subjects. A tungsten electrode with a tip diameter of 5-15 p was driven manually through skin, subcutaneous tissues and nerve sheath. From many recording sites in mixed nerve trunks neural impulses with an amplitude of 40 .uv were recorded in response to...

We introduce new prototype Apps for the automated recording of complete lessons, seminars, talks, etc using mobile devices running Android OS and iOS, which aim at supporting the recoding of academic lectures by students themselves. These Apps are free for use and are based on the experiences gained by the ICTP Science Dissemination Unit (SDU) in Trieste, Italy with its open source “Enhance you...

This paper describes a wearable system for the assessment of swim performance focusing on the description of the system and especially on the novel method for data transmission in water, and the algorithm used for extracting some parameters for the qualitative assessment of the performance. We placed a 3-axes Inertial Measurement Unit (IMU) on the athlete’s back in a specific swimsuit, which al...
