Demyelinating diseases can be modeled in animals by focal application of lysolecithin into the CNS. A single injection of lysolecithin into mouse spinal cord produces a lesion that spontaneously repairs over time. The goal is to study factors involved in de- and remyelination, and to test agents for enhancing repair.

Demyelination and Remyelination of Mouse Spinal Cord Neurons

This video demonstrates the method for inducing demyelination in mouse spinal cord neurons using lysolecithin injections, followed by remyelination through the migration and differentiation of oligodendrocyte precursor cells. The process impairs and then gradually restores neuronal signal transmission.

Demyelination takes place in multiple central nervous system diseases. A reliable in vivo drug delivery technique is necessary for remyelinating drug testing. This protocol describes an osmotic pump-based method that allows long-term drug delivery directly into the brain parenchyma and improves the drug bioavailability, with broad application in remyelination research.

Evaluating the Accuracy of Snap Judgments

Source: Diego Reinero & Jay Van Bavel—New York University Social psychologists have long been interested in the way people form impressions of others. Much of this work has focused on the errors people make in judging others, such as the exaggerated influence of central traits (such as "warm" and "cold"), the insufficient weight given to the context in which others' behavior takes place, and the tendency for people to make judgments that conform to their initial expectations about another.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
FAQs
Successful repair should be supported by evidence at two levels: restored myelin structure and improved axonal signaling. Structural measurements can show whether new myelin is present around nerve fibers, while nerve-conduction testing indicates whether those fibers transmit signals more effectively. Considering both prevents an anatomical change from being interpreted as functional recovery without corresponding evidence.
Each measurement addresses a different part of recovery. Histological staining, magnetic resonance imaging, and electron microscopy provide structural evidence related to myelin restoration, whereas nerve-conduction tests assess signaling through affected fibers. Combining these approaches gives a more reliable assessment than relying on one measurement, particularly when researchers need to determine whether repair has meaningful neurological consequences.
True repair should be supported by direct evidence of restored myelin rather than inferred only from reduced inflammation or improved symptoms. Structural findings from tissue-based methods or imaging can be compared with nerve-conduction results to test whether axonal signaling also improves. This distinction helps prevent temporary biological or clinical changes from being misclassified as regeneration.
Electron microscopy contributes detailed structural evidence about myelin and its relationship to nerve fibers. Its value is complementary to broader imaging and tissue-staining approaches because it helps examine repair at a more detailed level. In a multimodal assessment, these observations strengthen conclusions about whether newly detected changes represent restoration of myelin rather than an indirect effect of treatment.
Investigators can combine histological staining, magnetic resonance imaging, electron microscopy, and nerve-conduction testing to examine treatment effects from structural and functional perspectives. The resulting measurements are compared to determine whether a candidate therapy is associated with new myelin and better axonal signaling. This integrated approach supports comparison among treatments and helps separate repair from temporary changes.
It is particularly useful when studying recovery after demyelinating injury, assessing therapies for multiple sclerosis, or investigating other disorders involving myelin loss. The evaluation can characterize whether treatment-related changes reflect actual repair and whether that repair improves signaling. These findings support the development of regenerative therapies and provide evidence for comparing candidate interventions.
