Sentences with phrase «neural recordings»

Researchers have developed new technology for long - term stable neural recording.

The scientists cite problems that need to be addressed, such as to «increase the density and longevity of neural recordings in untethered, freely behaving animals» and come up with «beautiful models» of brain function that can be mathematically analyzed.

Spontaneous fluctuations are a hallmark of neural recordings, emergent over time scales spanning milliseconds to tens - of - minutes.

Complex and expensive to fabricate, these arrays are too bulky because the silicon support also incorporates the application - specific integrated circuit (ASIC) chip for neural recording.

The compact neural probe array consists of a three - dimensional probe array, a custom 100 - channel neural recording chip and a flexible polyimide polymer cable.

Next, working with anesthetized rats, they sent direct ionic current into the sciatic nerve in the legs and, using neural recording electrodes, recorded whether this current inhibited the activity of individual or groups of neurons at the spinal cord.

Then she validated her findings by showing the macaques additional faces, and accurately reconstructing what they'd seen using only neural recordings.

His team came up with the idea of a cognitively controlled hearing aid after they demonstrated it was possible to decode the attended target of a listener using neural responses in the listener's brain using invasive neural recordings in humans (Nature 2012).

The collaboration, led by Wen Shen and Mark Allen of the University of Pennsylvania, found that the extracellular matrix derived electrodes adapted to the mechanical properties of brain tissue and were capable of acquiring neural recordings from the brain cortex.

Such neural recording systems using wires to connect the implanted device to an external device can cause infections through the opening in the skull.

In order to identify the part of their brains responsible for seizures, the patients underwent 1 to 4 weeks of observation through electrocorticography (ECoG), a technique that provides precise neural recordings via electrodes placed directly on the surface of the brain.

To determine which neural recordings corresponded to the «ignored» and «attended» speech, the team reconstructed speech patterns from the brain's electrical activity using a mathematical model.

Scientists are working on using flexible neural recording fibers in order to develop devices that could help spinal cord injury or stroke sufferers regain their mobility.

In this process they played sounds for Ramsey, who was asked to try to repeat them aloud in his mind while neural recordings were taken via the electrode.

To analyze the neural recordings the researchers developed an odor - recognition data classifier and computational model that allowed them to compare the recognition scores between the natural flower scents and those embedded with various backgrounds.

«Lack of [stability in the neural recordings] has been a persistent problem with BCIs, and the investigators used a set of well - considered approaches to effectively address this for cursor control,» says Andrew Schwartz, a University of Pittsburgh neuroscientist who has done extensive work on brain - controlled devices but was not involved in the study.
