The probes are used in hundreds of neuroscience laboratories including the International Brain Laboratory, to record brain activity mostly in mice and rats. By revealing the activity of vast numbers of neurons, Neuropixels probes are allowing new approaches [ 3 ] to the study of brain processes such as sensory processing, decision making, [ 4 ...
The subsequent milestone involves the assembly of a brain-wide map of activity. This map of activity is being obtained with Neuropixels probes, which allow recording up to 300-1000 neurons simultaneously. [7] Other recording technologies, such as calcium imaging, will be used in the second phase. These data will then be analyzed and integrated ...
The performance of the Neuropixels probes and their potential for transformational neuroscience experiments was described in a November 9, 2017 paper published in Nature. [28] In 2019, The New York Times reported that imec's Neuropixels technology is widely recognized as the most advanced method of gathering data from brain cells. [29]
Microelectrode arrays (MEAs) (also referred to as multielectrode arrays [1] [2]) are devices that contain multiple (tens to thousands) microelectrodes through which neural signals are obtained or delivered, essentially serving as neural interfaces that connect neurons to electronic circuitry.

However, scientists have tried to introduce the newer, more accurate term 'photoactivatable probes'. Both nomenclatures are currently in use. Major discoveries were made in the following years with caged neurotransmitters , such as glutamate , which is used to map functional neuronal circuits in mammalian brain slices . [ 3 ]
Second way: Make sensors super small in all dimensions. Advantages: Can be injected, easier to use. Might last longer as they're less likely to trigger the body's immune response. But, they're quite different from current sensors and need more testing before they're ready for patients.
Probes are published on the Portal along with a highlight of the probe’s validation data, and it takes a few weeks for the SAB ratings (denoted with 0 to 4 stars) to emerge. Probe pages also contain SAB comments and links to related databases or sources (e.g., journals) where additional information can be found. Probes must receive an average ...
