""Implantable optical devices that target neurons can be improved using miniature coils smaller than a grain of rice using optogenetic technology. Scientists can propagate pulses of light using the method to turn protein ...
Two-photon laser scanning microscopy imaging is commonly applied to study neuronal activity at cellular and subcellular resolutions in mammalian brains. Such studies are yet confined to a single functional region of the brain. ...
A new microscope breaks a long-standing speed limit, recording footage of brain activity 15 times faster than scientists once believed possible. It gathers data quickly enough to record neurons' voltage spikes and release ...

(Phys.org)—Researchers are working on the early stages of a brain-computer interface (BCI) that can tell who you're listening to in a room full of noise and other people talking. In the future, the technology could be incorporated ...
Object-recognition systems are beginning to get pretty good—and in the case of Facebook's face-recognition algorithms, frighteningly good.

(PhysOrg.com) -- The ability to see objects oriented differently to the background, which is known as orientation-based saliency, has long been thought to be confined to mammals, but a new study has found that archer fish ...
An interdisciplinary team of researchers led by biologists at the University of Massachusetts Amherst recently published the results of a first-of-its-kind study investigating the links between gene expression and brain evolution ...

A team of researchers from University College London, Columbia University and Oxford University has developed a new approach to conducting transcriptomics and has used it to reveal the properties of 35 neuron subtypes in ...
The term visual cortex refers to the primary visual cortex (also known as striate cortex or V1) and extrastriate visual cortical areas such as V2, V3, V4, and V5. The primary visual cortex is anatomically equivalent to Brodmann area 17, or BA17.
