A neural pathway connects one part of the nervous system to another using bundles of axons called tracts. The optic tract that extends from the optic nerve is an example of a neural pathway because it connects the eye to the brain; additional pathways within the brain connect to the visual cortex.
Because the neural tube gives rise to the brain and spinal cord any mutations at this stage in development can lead to fatal deformities like anencephaly or lifelong disabilities like spina bifida. During this time, the walls of the neural tube contain neural stem cells , which drive brain growth as they divide many times.
The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience.These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development, and continues to develop postnatally.
A number of online neuroscience databases are available which provide information regarding gene expression, neurons, macroscopic brain structure, and neurological or psychiatric disorders. Some databases contain descriptive and numerical data, some to brain function, others offer access to 'raw' imaging data, such as postmortem brain sections ...

Epigenetic medicine encompasses a new branch of neuroimmunology that studies the brain and behavior, and has provided insights into the mechanisms underlying brain development, evolution, neuronal and network plasticity and homeostasis, senescence, the etiology of diverse neurological diseases and neural regenerative processes.
Methyl-CpG binding protein 1 represses miR-184, which is a microRNA responsible for proliferation of adult neural stem/progenitor cells (aNSCs) along with the inhibition of differentiating these cells. miR-184 regulates embryonic brain development by binding to the mRNA for the Numblike (Numbl) protein and altering its expression.
Stages of neuronal development in the fetal cerebral cortex Model of mammalian neurogenesis [4]. During embryonic development, the mammalian central nervous system (CNS; brain and spinal cord) is derived from the neural tube, which contains NSCs that will later generate neurons. [3]
