Central nervous system neurons are unable to regenerate unlike peripheral nervous system neurons due to inhibitory factors and low cAMP levels in the central nervous system. However, if peripheral and central nervous system branches are separated, the peripheral branch can cause cAMP levels to rise and allow the central branch to regrow. This research aims to develop a genetically manipulable model to identify molecules regulating axon regeneration. Caenorhabditis elegans is a suitable model as it has a simple nervous system with identifiable axon paths and synapses, as well as being small and transparent, and its genes, regeneration patterns, and mechanisms are similar to vertebrates.
Not every brain has the same level of capability to adapt to environmental stimulation. It depends on what medical professionals call brain plasticity or neuroplasticity, or how the central nervous system (CNS) is able to change – for better or worse – at any age

Stem cell derived from human umbilical cord or bone marrow improves mobility with spinal cord injuries providing the first physical evidence that the therapeutic use of these cells can help restore motor skills lost from acute spinal cord tissue damage.

There are multiple characteristics to examine during fetal brain growth and development. Cortical surface area and cerebral volume are closely correlated with gestational age. Grey matter and white matter volume increase dramatically during the last few weeks of the third trimester. At the cellular and molecular levels, diffused white matter is involved with mylelination, cytostructural support, and communication. Myelination is closely related to the quality of neuronal connectivity.

The dance between Glia and Neurons is critical to the development and maintenance to CNS. Did you know: • up to 90% of the cells in the vertebrate nervous system are “not neurons” • make > 50% of the brain volume. This is a great overview to anyone that wants to learn more.

This is a journal club presentation on the manuscript by Owen et al, published in May 2021 in the journal Developmental cell. It describes how the myelinoids were derived from the iPSCs and can be considered as model to study myelin biology.

Bom Estudo!
As Associate Principal at The Monitor Group (now Monitor Deloitte) in China, part of my of my role was helping train 1st Year consultants. This is the summary presentation from a day long Masterclass in the commonly used techniques in assessing a firm's "true" value.
The field of neuroscience is undergoing significant change. The two main cell families that make up the brain, neurons and glial cells, each concealed a hybrid brain cell that fell somewhere in the middle.
Regeneration of Brain with new understanding gives us good ground to be optimistic in matters of research and also day to day clinics. This presentation at the most introduces you to the potential stride of the field.

Seminar 4. October 22, 2013 Dr. Aixa Alfonso: The Use of C.elegans as a Model to Study Neural
Development, Function and Dysfunction
Central nervous system (CNS) neurons are incapable of regenerating whereas peripheral nervous system
(PNS) neurons are able to do so in adult warm-blooded vertebrates. The inhibitory environment,
essential axon promoting growth factors, and the low levels of endogenous cyclic adenosine
monophosphate (cAMP) in the CNS are responsible for this incapacity. The inability of regeneration in
the CNS occurs in the branch. Nevertheless, if the PNS and CNS braches are segregated consecutively,
the PNS promotes the levels of cAMP to rise, hence allowing the CNS branch to regrow. The purpose of
this research is to elaborate a genetically manageable model system that detects innovative molecules
responsible for regulate axon regeneration. C. elegans serves as a proper model system, because it has a
modest nervous system with recognizable axon trajectories and synaptic connections in addition to
optimal size and transparency. Their genes, regeneration patterns and molecular mechanisms share
similar characteristics with vertebrates.
