Abstract: This chapter informs the reader of the discovery of nerve growth factor, how it plays an important role in bioprinting by directing the growth of the axons of nerve cells along specific paths to repair peripheral nerve injuries, and of the nascent efforts in bioprinting spinal cord scaffolds that may aid in the repair of spinal cord injuries. The chapter apprises the reader of the glial family of cells that provide myelination (insulation) for nerves in the central nervous system. Glial cells are as numerous in the central nervous system (i.e., the brain and spinal cord) as neurons (nerve cells). The chapter also explains fluorescently tagged calcium ion flow within bioprinted nerve tissue. Intracellular calcium—calcium within cells—controls key cellular functions in all types of neurons. For example, nerve cells cause a release of calcium ions that initiate muscle contraction.

Abstract OBJECTIVE Hemangiopericytomas, vascular tumors arising in soft tissue, are relatively rare in the central nervous system; they comprise less than 1% of all hemangiopericytomas. Central nervous system hemangiopericytomas occur primarily in the epidural space of the brain and spinal cord. There are no previous reports of subpial, extramedullary growing central nervous system hemangiopericytomas. CLINICAL PRESENTATION We document the first case of a subpial hemangiopericytoma with extramedullary growth in the thoracic spine. The patient was a 31-year-old man who developed progressively worsening left lower limb numbness that was followed by gait disturbance over the course of 4 months. INTERVENTION Magnetic resonance imaging revealed an intradural tumor at the T4–T6 level of the thoracic spine. Because the patient's symptoms progressed, he underwent resection of the tumor, which had arisen in the spinal cord subpially without attachment to the dura mater. CONCLUSION The pathological diagnosis was hemangiopericytoma. Differential diagnoses include hemangioblastoma, meningioma, schwannoma, and solitary fibrous tumor, the clinical course and prognosis of which are different from hemangiopericytoma. Our experience indicates that hemangiopericytomas can occur as intradural tumors arising from the subpial portion.

Superficial Siderosis (SS) of Central Nervous System is a rare disease characterized by the deposit of hemosiderin in the brain and spinal cord. Clinically, it is characterized by progressive sensorineural ataxia and deafness associated with injury of superior motor neuron. The diagnosis is made by magnetic resonance imaging (MRI) of the encephalon and spinal cord. The objective of the study is to report the case of a patient with characteristic elements of the syndrome, accompanied in a private medical clinic.

Central Lesions

Rothmann points out how important it is to surgeons that the localisation of lesions in the brain and spinal cord should be made with the utmost accuracy. In many cases diseases do not strike suddenly upon a nervous system previously intact. Often the circulation has been previously deranged by arterial sclerosis, which prepares the way for transitory hemiplegia or aphasia. Sometimes there is loss of function after central lesions, which disappears in longer or shorter time. Goltz and his followers have treated many effects following the extirpation of the whole or part of the cerebrum as due to what they call inhibition (Hemmung). Thus the functions of the spinal cord are much impaired after removal of the cerebral ganglia, or the lower portion of the cord loses its reflex function after section higher up, but after a while it again resumes its act$ibon.

This chapter looks at electrophysiological studies of the central nervous system and peripheral nervous system—the core investigations in clinical neurophysiology. These include electroencephalography, which is of value to diagnose epilepsy caused by focal or diffuse brain diseases, electromyography and nerve conduction studies, which are of value to diagnose diseases in nerves and muscles, and evoked potentials, which are of value to diagnose diseases of white matter in the brain and spinal cord.

Abstract The genus Myxobolus, parasites that infect fishes, which cause myxobolosis, includes spore organisms belonging to the phylum Myxozoa and represents approximately 36% of all species described for the entire phylum. This study describes lymphocytic meningoencephalomyelitis associated with Myxobolus sp. infection in the brain and spinal cord (the central nervous system, CNS) of Eigenmannia sp., from the Amazon estuary region, in the Administrative District of Outeiro (DAOUT), Belém, Pará, Brazil. In May and June 2015, 40 Eigenmannia sp. specimens were captured from this region and examined. The fish were anesthetized, slaughtered and dissected for sexing (gonad evaluation) and studying parasites and cysts; after diagnosing the presence of the myxozoans using a light microscope, small fragments of the brain and spinal cord were removed for histological processing and Hematoxylin-Eosin and Ziehl-Neelsen staining. Histopathological analysis of the brain and spinal cord, based on histological sections stained with Hematoxylin-Eosin, pronounced and diffuse edema in these tissues, and congestion, degeneration, and focal necrosis of the cerebral cortex. The present study describes lymphocytic meningoencephalomyelitis associated with infection by Myxobolus sp. in the central nervous system of Eigenmannia sp.

The Dmrt genes encode the transcription factor containing the DM (doublesex and mab-3) domain, an intertwined zinc finger-like DNA binding module. While Dmrt genes are mainly involved in the sexual development of various species, recent studies have revealed that Dmrt genes, which belong to the DmrtA subfamily, are differentially expressed in the embryonic brain and spinal cord and are essential for the development of the central nervous system. Herein, we summarize recent studies that reveal the multiple functions of the Dmrt genes in various aspects of vertebrate neural development, including brain patterning, neurogenesis, and the specification of neurons.
