Ideally, interference in neural measurements due to signals from nearby muscles can be completely eliminated with the use of tripolar nerve cuff electrodes, in combination with appropriate amplifier schemes. In practice the cuff departs from its ideal model leading to cuff imbalance. As a result, the output nerve signal of such amplifiers has been widely reported to be degraded by interference,...

Background: In addition to biochemical gradients and transcriptional networks, cell behaviour is controlled by endogenous bioelectrical signals resulting from the action of ion channels pumps. Cells are regulated not only their own membrane resting potential (Vmem) but also Vmem neighbouring cells, establishing networks through electrical synapses known as gap junctions. V mem primary factor in...

Multiple recent studies have highlighted the role of bioelectric signals in large-scale pattern formation in the body’s spatial structure and organs, and in organ phylogenesis and ontogenesis, during embryogenesis and regeneration [1-5]. These signals form one layer of physiological control and work in conjunction with biochemical and genetic pathways [6-10]. The bioelectrical state of cells an...

OBJECTIVE The association between rarely used anthropometric measurements (e.g., mid-upper arm, forearm, and calf circumference) and metabolic syndrome has not been proven. The aim of this study was to assess whether mid-upper arm, forearm, calf, and waist circumferences, as well as waist/height ratio and waist-to-hip ratio, were associated with metabolic syndrome. METHODS We enrolled 387 sub...

Human faces transmit multiple valuable signals, and neuroimaging studies have shown that the amygdala is active in response to facial stimuli. However, little has been known about the temporal profile of amygdala activation during facial signal processing until recently. Here we review three recent studies conducted by our group in which we recorded amygdala intracranial electroencephalography ...

We describe a sensitive plant monitoring system by the detection of the bioelectric potentials in plants with boron-doped diamond (BDD) electrodes. For sensor electrodes, we used commercially available BDD, Ag, and Pt plate electrodes. We tested this approach on a hybrid species in the genus Opuntia (potted) and three different trees (ground-planted) at different places in Japan. For the Opunti...

This paper investigates facial communicative signals (head gestures, eye gaze, and facial expressions) as nonverbal feedback in human-robot interaction. Motivated by a discussion of the literature, we suggest scenario-specific investigations due to the complex nature of these signals and present an object-teaching scenario where subjects teach the names of objects to a robot, which shall term t...
