For an implantable system for the recording of brain signals from neonatal mice the design specifications for the weight and the size of a implantable system are very tough. The animals are very small and light weight (1–3 cm, 2– 3 g) and the recording data rate is very high (3,5 Mbit/s). Thus, the system has to be extremely small. With state of the art technique it is not possible to set up a wireless...
In neuroscience research the development of the brain and the treatment of diseases like certain forms of epilepsy is analysed with genetic mouse disease models. For the special case of the recording from neonatal mice a custom designed integrated circuit is presented. Neonatal mice are only two to three centimetres large and have a weight of only a few gram. Thus, the recording circuitry has to be...
This paper details an array of switch resistor based memristor emulators with integrate & fire based neuron ASIC for the development of memristor based pattern recognition. The designed ASIC has 4 memristor emulators with a conductance range from 195 nS to 190 uS; processing has been planned to be off-chip to get the freedom of programmability of any function in ASIC. The ASIC has 2 integrate...
This paper details a fully programmable floating memristor (resistor with memory) emulator ASIC designed for biologically inspired memristive learning. Since real memristor is not commercially available, a compact memristor emulator is needed for device study. The designed ASIC has a memristor emulator with conductance range from 4.88nS to 4.99µS (200KΩ to 204.8MΩ). The memristor emulator is a switched-resistor...
This paper presents intramuscular electromyogram (EMG) signals obtained with a fully implantable measurement system that were recorded during goal directed arm movements. In a first implantation thin film electrodes were epimysially implanted on the deltoideus of a rhesus macaque and the encapsulation process was monitored by impedance measurements. Increase of impedance reached a constant level after...
This work presents intramuscular measurements of the electromyogram (EMG) during goal directed arm movements. Thin film electrode arrays were epimysially implanted on the deltoideus of a rhesus macaque and the encapsulation process was monitored by impedance measurements. Increase of impedance plateaued after four weeks indicating a complete incorporation of electrodes. EMG recorded with these electrodes...
