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 ...
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 ]

Increasingly sharp probe tips have been of interest to researchers for applications in the material, life, and biological sciences, as they can map surface structure and material properties at molecular or atomic dimensions. The history of the probe tip can be traced back to 1859 with a predecessor of the modern gramophone, called the ...
A Berkovich tip, with "a" denoting the half angle A scanning electron microscope image of a Berkovich tip used in a nanoindenter. A Berkovich tip is a type of nanoindenter tip used for testing the indentation hardness of a material.
A test probe is a physical device used to connect electronic test equipment to a device under test (DUT). Test probes range from very simple, robust devices to ...
