Using light to manipulate neuron excitability

Nearly 20 years ago, scientists developed ways to stimulate or silence neurons by shining light on them. This technique, known as optogenetics, allows researchers to discover the functions of specific neurons and how they ...

How neurons autonomously regulate their excitability

Nerve cells can regulate their sensitivity to incoming signals autonomously. A new study led by the University of Bonn has now discovered a mechanism that does just that. The German Center for Neurodegenerative Diseases and ...

Ganglion cells created in mice in bid to fix diseased eyes

While fish, reptiles and even some birds can regenerate damaged brain, eye and spinal cord cells, mammals cannot. For the first time, non-neuronal cells have been induced to mimic specific ganglion cells in the eyes of mice.
