Research identifies earlier origin of neural crest cells

Neural crest cells—embryonic cells in vertebrates that travel throughout the body and generate many cell types—have been thought to originate in the ectoderm, the outermost of the three germ layers formed in the earliest ...

Embryo's early development revealed in a dish

During embryonic development, the entire nervous system, the skin and the sensory organs emerge from a single sheet of cells known as the ectoderm. While there have been extensive studies of how this sheet forms all these ...

Study answers longstanding cell-development riddle

During the lifetime of a body—whether human, fish or any other type of vertebrate—cells die, making room for fresh new cells to carry on vital processes. The dead cells must be cleared away, though, and debris removal ...

Brain waves detected in mini-brains grown in a dish

Scientists have created miniature brains from stem cells that developed functional neural networks. Despite being a million times smaller than human brains, these lab-grown brains are the first observed to produce brain waves ...

Inhibitory neurons have two types of impact on brain oscillations

Studying the brain involves measuring the activity of billions of individual brain cells called neurons. Consequently, many brain measurement techniques produce data that is averaged to reflect the activity of large populations ...
