Scientist Observes real Time Generation of Neurones in Mammals

A scientist at the Hebrew University of Jerusalem says that he has observed the real time generation of neurones in a mammals brain, the first ever claim of such kind in the world. Dr. Adi Mizrahi of the Department of Neurobiology, Alexander Silberman Institute of Life Sciences, used mous...

Zebrafish offer clues to treatments for motor neurone disease

...ve found that these fish are able to produce motor neurones cells that control all muscle activity such as sp...ow zebrafish can regenerate large numbers of motor neurones after damage to the spinal cord and how these motor neurones are produced by natural stem cells could help in f...

Memantine and Alzheimer's disease

..., and has negative effects on neuronal communication at high concentrations. At lower concentrations, memantine was able to enhance signalling between neurones of the hippocampus (the main brain area affected in Alzheimers disease) and was indeed able to reverse learning and memory deficits. However, a pharma...

Large Intake of Calcium from Dairy Food Linked to Dementia in Elders

...is calcification may narrow the blood vessels and make them less flexible, reducing the blood flow through them. When it happens in the brain, neurones may die as a result of blood deprivation, which in turn may cause the lesions that increase the risk of cognitive impairment, dementia, depression and...

Alzheimer's - From Curiosity To Worldwide Disease

...e Auguste D. is deviant from all known disease patterns." Since, scientist understood that the disease is caused by a gradual degeneration of the neurones and usually sets on after the age of 65. Many patients no longer recognise family members and friends, have orientation problems and struggle wit...

The 'Mad Cow' Disease And Protein

... findings enabled the research team to establish that the PrPC is a protein involved in the neuronal metabolism of calcium. Moreover, the existence of neurones without PrPC and surrounded by perineuronal nests breaks with the hypothesis, to date, that the disappearance of such nests – a special form of extrac...

This was a surprising finding, because the interneurones suppress those neurones in the hippocampus which are supposed to write information to the cerebral cortex precisely during phases of high activity.

They found that as well as being sensitive to blue light, melanopsin uses light at different wavelengths to regenerate itself. In so...
