The gene Cdkn1c could have been considered an open-and-shut case: Mice in which the gene is removed are larger and have bigger brains, so Cdkn1c should function to inhibit growth. This rationale has led to Cdkn1c being studied ...

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 ...

""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 ...
How do we choose our food? By studying the neurobiological mechanisms involved in food choices of rodents, neuroscientists at the University of Geneva (UNIGE), Switzerland, have identified the important and lasting influence ...

A team of researchers with affiliations to institutions in Brazil, Portugal and Spain has found evidence of a continuous phase transition occurring in the brains of rats when they move from sleep to wakefulness. In their ...
The laboratory of researcher Eloísa Herrera has discovered that during the development of the brain's visual areas, the two retinas communicate with each other temporarily through nervous projections. This connection is ...

The part of the brain that processes visual information, the visual cortex, evolved over the course of millions of years in a world where reading and writing didn't exist. So it's long been a mystery how these skills could ...
