Sentences with phrase «with microelectrodes»

Linsenmeier et al. [1] measured intraretinal PO2 with microelectrodes in cats with long - standing diabetes and concluded that the retina was hypoxic in the early stages of retinopathy.

The surface of the chip is covered with microelectrodes and the chip is connected to a power source, with the power converted to high - frequency sound waves.

Not exact matches

At the same time, the activity of hundreds of nerve cells was measured with so - called microelectrode arrays.

What's more is that each microelectrode array is made up of eight «tines,» each with eight microelectrodes which can record from a total 64 subregions of the brain at once.

In a new study by Flesher et al., microelectrode arrays were implanted into the primary somatosensory cortex of a person with spinal cord injury and, by delivering current through the electrodes, generated sensations of touch that were perceived as coming from his own paralyzed hand.

Researchers at the University of Southern California Viterbi School of Engineering have developed thin, flexible polymer - based materials for use in microelectrode arrays that record activity more deeply in the brain and with more specific placement than ever before.

Also, the team plans to create devices with even higher density, including a double - sided microelectrode array with 64 electrodes per tine instead of eight — making for a total of around 4,000 electrodes placed in the brain at once.

Researchers are probing the brain with increasingly powerful tools, including superfast magnetic resonance imagers and microelectrodes that can detect the murmurs of individual brain cells.

We recorded neural population activity with arrays of microelectrodes implanted in the PPC of a tetraplegic subject.

For example, in nonhuman primates, stimulation using microelectrodes improved face categorization (Afraz et al., 2006), modulated motion perception with great specificity (Fetsch et al., 2014), and increased the learning rate during a reinforcement learning task (Williams and Eskandar, 2006).

But the number of neurons at a time with which microelectrode arrays can interface must be increased several-fold while making sure the scale - up does not cause damage to brain tissue.
