Surgery can be done in case a peripheral nerve has become cut or otherwise divided. This is called peripheral nerve reconstruction. The injured nerve is identified and exposed so that normal nerve tissue can be examined above and below the level of injury, usually with magnification, using either loupes or an operating microscope. If a large ...
Inner ear regeneration is the biological process by which the hair cells and supporting cells (i.e. Hensen's cells and Deiters cells) of the ear proliferate (cell proliferation) and regrow after hair cell injury. This process depends on communication between supporting cells and the brain.
The axolotl is less commonly used than other vertebrates, but is still a classical model for examining regeneration and neurogenesis. Though the axolotl has made its place in biomedical research in terms of limb regeneration, [19] [20] the model organism has displayed a robust ability to generate new neurons following damage.
Neuroprosthetics (also called neural prosthetics) is a discipline related to neuroscience and biomedical engineering concerned with developing neural prostheses.They are sometimes contrasted with a brain–computer interface, which connects the brain to a computer rather than a device meant to replace missing biological functionality.
Preliminary diagnostic procedures include ear examination, hearing and vestibular testing. Typical symptoms include unilateral tinnitus, progressive hearing loss and vertigo. Usually diagnostic sensitivity is increased with one or more otological symptom. The rate of VS pick up with unilateral tinnitus alone using MRI has been shown to be <0.1% ...
In cerebellar granule cells and cortical neurons, E2F1 can trigger neuronal apoptosis through activation of Bax/caspase-3 and the induction of the Cdk1/FOXO1/Bad pathway (Giovanni et al., 2000). The downregulation of p130/E2F4 (a complex which has been shown to maintain the post mitotic nature of neurons) induces neuronal apoptosis by ...
3. Your ears are plugged up. Blockages like ear wax (or, in very rare cases, a tumor) could cause ringing in your ears due to pressure on the nerves that run through your ear canal. You might also ...
This can only be done where the functional associations of these neurons are approximately known. Because of the complexity of neural processing and the lack of access to action potential related signals using neuroimaging techniques, the application of brain implants has been seriously limited until recent advances in neurophysiology and ...
