Tarantula venom points scientists to a whole new mechanical pain receptor

And it all stems from the way tarantula venom paralyzes its prey.The researchers named the two toxins δ-theraphotoxin- Hm1a (Hm1a) and δ-theraphotoxin-Hm1b (Hm1b).

In mice, a possible means to counteract multiple sclerosis

In mice, a possible means to counteract multiple sclerosis In either case, the length of the cell, the connection between the in-point and the out-point, is called the axon.It is responsible for carrying signals over whatever distance the signal must travel to get to the next neuron, or its ultimate destination.

How neuromorphic ‘brain chips’ will begin the next era in computing

How neuromorphic ‘brain chips’ will begin the next era in computing Part of the reason a digital computer is more efficient than a human being is its transistors can fire with incredible speed — but so can our neurons.Similarly, we will eventually look back at the attempt to do learning operations with digital chips, including GPUs, as inherently unwise or even silly.

Scientists develop a memristor that can be conditioned just like a real synapse

Scientists develop a memristor that can be conditioned just like a real synapse The memristor is made of a silicon-oxygen-nitrogen material laced with clumps of silver nanoparticles at the electrical terminals.When current is applied across the memristor, the silver nanoparticles shuffle around within their parent oxynitride matrix, to line up within a lightning-bolt-like path of least electrical resistance.

New probe measures electrical activity of hundreds of individual neurons in living brains

New probe measures electrical activity of hundreds of individual neurons in living brains To move beyond historically difficult and damaging methods of taking these readings, researchers from Caltech have demonstrated a minimally invasive probe for doing in vivo electrophysiology: real-time electrical recordings of living nerves in the brain.The probe can measure electrical activity in three dimensions, which could be a huge breakthrough for our understanding of cognition and neural activity.
