When we suppressed the ALS mutation in the brains of animals, onset of the disease was delayed, the animals lived longer, spinal motor neurons survived longer, and the neuromuscular junctions stayed healthy longer,» said Svendsen, the Kerry and Simone Vickar Family Foundation Distinguished Chair in Regenerative Medicine.

Finally, the researchers tested this circuitry in live animals, artificially turning on the motor neurons in anesthetized mice and then looking to see how the auditory cortex responded.

Since olfactory sensory neurons regenerate throughout life, even in humans, the investigators were able to measure neuron regeneration in specific animal models.

They counted the numbers of APs and ALs in different body tissues — intestine, muscle, pharynx (i.e., the animal's foregut), and neurons — at different time points during the adult life of C. elegans, and used chemical blockers to learn more about the dynamics of the process.

Albeanu and colleagues, including Arkarup Banerjee and Fred Marbach, graduate students in the Watson School for Biological Sciences at CSHL and co-first authors of the Neuron paper, conducted experiments in living animals that revealed a mechanism for adjusting olfactory signal gain.

Some theoretical models suggested that new neurons destabilize memories already stored in the hippocampus by degrading the information there, but the idea had never been explored in live animals.

For example, it could be used to image neurons in living mice by combining the Raman scattering technique with existing methods in which tiny windows are implanted in the brains and spinal cords of laboratory animals.

In a live animal, these neurons would then relay that information to the brain (Nature Photonics, DOI: 10.1038 / nphoton.2012.10).

THE firing of every neuron in an animal's body has been recorded, live, for the first time.

«Our earlier work was the first to clearly show in vivo (in a living animal) that mature astrocytes can be reprogrammed to become functional neurons without the need of cell transplantation.

This method uses light to precisely control the activity of specific neurons in living, even moving, animals in real time.

The researchers focused on a process — known as «homeostatic scaling down» — that has been well - studied in lab neurons but not before in living animals.
