Computer Electronics Meet Animal Brains
Till the recent times, simulation, data collection, and data analysis have been done using the computers by the neurobiologists. But interacting
directly with nerve tissue in live, behaving animals is a novel venture. The voltage waveforms are used to transmit and process information in both the neurons and the computers. But the effort to page link the electronic signaling of digital computers and that of the nerve tissue in the live animals in on. The areas of MEMS, CMOS electronics, and embedded computer systems have grown so that computers can be linked to the neurons and especially the ones with known neural functions. The MEMS probes, microclamps, microprobe
arrays etc are used to make a direct contact with the brain cells without making a long term damage to the cells. The low-power amplifiers and analog-to-digital converters can now be integrated into a single CMOS die. Also, a single silicon chip can now contain all the computer circuitry and the device can run on power ratings as small as nanowatts.
INTEGRATING SILICON AND NEUROBIOLOGY
The task of remembering , modulating, and controlling an animal’s behaviour, thought, movement and sensation is carried out by the Neurons and neuronal networks. The modern neurobiology is all about understanding these tasks. The conventional techniques involve examining the brain cells tied to sensory inputs, integrative processes, and motor outputs . For understanding the internal working of a cell intracellular micropipettes to impale or patch clamp single cells are used. The extracellular wires or micromachined probes are used for interrogating multisite patterns of extracellular neural signaling.
