The human brain is made up of billions of nerve cells (neurons) that communicate with each other in vast, interconnected ...

Unraveling a key brain chemical, galanin, new research in fish shows it typically calms brain activity. However, stress can weaken this calming effect, leading to overactivity and seizures. This ...

Beyond genes! New research on zebrafish embryos reveals physical forces and cell stickiness are crucial for shaping the brain ...

The neuropeptide galanin modulates whole-brain activity and stress responses in zebrafish, revealing a complex, receptor-dependent role in seizure regulation with implications for epilepsy, and ...

Are recycled bottles safe? A study suggests chemical mixtures in recycled plastics might affect metabolism and hormone ...

Ribosomes are tiny molecular machines inside all living cells that build proteins, and ribosome biogenesis is the complex, multi-step process by which they are made. During brain development ...

With remarkable genetic conservation, optical transparency, rapid embryonic development, and a rich repertoire of genetic tools, zebrafish are now extensively employed to unravel the molecular and ...

A team of scientists at the MRC Laboratory of Medical Sciences (LMS) has uncovered a previously unknown mechanism that controls how genes are switched ‘on’ and ‘off’ during embryonic ...

Incredible images created by our scientists using advanced microscopes are helping to drive biological discovery ...

We monitored real-time in vivo levels of serotonin release in the digestive system of intact zebrafish embryos during early development (5 days postfertilization, dpf) using differential pulse ...

The factors regulating the activity of retrotransposons in early embryo development. Highly coordinated molecular mechanisms, including cis- and trans-acting, RNA decay, and epigenetic modifications ...
