Abstract The correct human brain function is dependent on the activity of non‐neuronal cells called astrocytes. bioelectrical properties astrocytes in vitro do not closely resemble those displayed vivo and former are incapable generating action potential; thus, reliable approaches for noninvasive electrophysiological recording remain challenging biomedical engineering. Here it found that primary grown a device formed by forest randomly oriented gold coated‐silicon nanowires, resembling...
Odor identification is one of the main tasks olfactory system. It performed almost independently from concentration odor providing a robust recognition. This capacity to ignore information does not preclude system estimating itself. Significant experimental evidence has indicated that able infer simultaneously identity and intensity. However, it still unclear at what level or levels pathway this segregation occurs. In work, we study whether input stage bulb: glomerular layer. To end, built...
Experimental studies have shown that the reactions to external stimuli may appear only few hundreds of milliseconds after physical interaction stimulus with proper receptor. This behavior suggests neurons transmit largest meaningful part their signal in first spikes, and than spike latency is a good descriptor information content biological neural networks. In this paper property has been investigated an artificial sensorial system where single layer spiking trained data generated by...
Layered Double Hydroxides (LDHs) are well known class of materials that since their discovery, happened more than one century ago, have been used in a large range fields (catalysts, drug delivery media, Oxyanion adsorption, etc.). LDHs characterized by Surface/Volume ratio and strong ability to adsorb molecules any kind. Even if these two characteristics make it very good candidate be gas sensor, not deeply investigated yet this direction. In work, some evidences the promising properties...
Abstract Sensitivity, selectivity and stability are decisive properties of sensors. In chemical gas sensors odor recognition can be severely compromised by poor signal stability, particularly in real life applications where the exposed to unpredictable sequences odors under changing external conditions. Although olfactory receptor neurons nose face similar stimulus likewise conditions, is very stable odorants reliably identified independently from past perception. We postulate that...

Electrocorticography (ECoG) is receiving growing attention for both clinical and research applications thanks to its reduced invasiveness ability of addressing large cortical areas. These benefits come with a main drawback, i.e. limited frequency bandwidth. However, recent studies have shown that spiking activity from neurons can be recorded when the ECoG grids present following combined properties: (I) conformable substrate, (II) small neuron-sized electrodes (III) low-impedance interfaces....
Metal-oxide semiconductor gas sensors offer valuable advantages, such as high sensitivity, low cost and small dimensions.
