Human brain imaging has identified structural changes in gray and white matter that occur
with learning. However, ascribing imaging measures to underlying cellular and molecular …

White matter is the brain region underlying the gray matter cortex, composed of neuronal
fibers coated with electrical insulation called myelin. Previously of interest in demyelinating …

Two-way communication between neurons and nonneural cells called glia is essential for
axonal conduction, synaptic transmission, and information processing and thus is required for …

Molecular approaches to understanding the functional circuitry of the nervous system
promise new insights into the relationship between genes, brain and behaviour. The cellular …

Activity-dependent release of ATP from synapses, axons and glia activates purinergic
membrane receptors that modulate intracellular calcium and cyclic AMP. This enables glia to …

Myelin, the insulating layers of membrane wrapped around axons by oligodendrocytes, is
essential for normal impulse conduction. It forms during late stages of fetal development but …

… with bn(r,z) T' the appropriate term must be extracted from the expression for bT(r,z). By
expanding the E j (2r IW;) term in Eq. (7) as a power series,2 the term that is quadratic in r of 6. T( …

Formation of myelin, the electrical insulation on axons produced by oligodendrocytes, is
controlled by complex cell-cell signaling that regulates oligodendrocyte development and …

The synapse is the focus of experimental research and theory on the cellular mechanisms of
nervous system plasticity and learning, but recent research is expanding the consideration …

Tumor-associated macrophages (TAMs) are essential components of the cancer
microenvironment and play critical roles in the regulation of tumor progression. Optimal therapeutic …
