During the prenatal period, the fetus begins to form one of the most complex structures in nature, the human brain. This process is called neural embryogenesis and it represents one of the most complicated processes in prenatal life. The process relies on the tight regulation of behavior of the cells that will make up the brain. Neuronal stem cells (NSC) play a key role in embryonic brain development. Our improved understanding of the harmful effect of lead on prenatal neurodevelopment calls for increased attention to avoid the exposure of future mothers to this toxic element. It is believed that millions of pregnant women around the world are regularly exposed to high concentrations of lead in food and drinking water
Dr Fagogenis Gerasimos from Athens University School of Medicine, Greece. His current research is basically focused on transmission of human brain’s electromagnetic waves. Brain-to-brain transmission comprises not only cognitive but also sensory interpretations. The quality of perception and interaction from person to person coincides with reality in some fields while simultaneously and at any moment intangible sensory and cognitive images noeticforms Gestalt are realized bilaterally: Psychesthetism is the essence in perception and comprehension. Always, speech and interaction simulate open space conversation.
Although cancer chemotherapy does work very well for many cancer patients, most certainly it can also cause dangerous and permanent brain damage. Chemotherapy can change how the brain works through changing the level of neurotransmitters. It can even change the structure of the brain, reducing its volume and reducing grey matter in the brain. Eventually this leads to cognition impairment which is strongest shortly after finishing the chemotherapy but can persist for decades after.
Scientific data point to the benefits of moderate drinking: it may help to keep a higher level of cognition and prevent age-related deterioration of brain functions. The key is not to go over your limit. Keep your alcohol intake on a moderate level and stay healthy. Recent reports also brought to light the findings that moderate alcohol consumption can influence the size of the hippocampus in elderly population. Compared to abstainers, moderate drinkers have a larger hippocampus and better episodic memory.
From this study, we can infer that new memories may also still be formed in the early stages of Alzheimer’s disease in humans, but that their retrieval may be compromised. Importantly, thismemory loss may be overcome using brain stimulation. Although this technology is still far from being applicable to humans, this study brings new optimism to Alzheimer’s diseasetherapy.
