The antennas contained in mobile phones, including smartphones, emit radiofrequency (RF) radiation (non-ionizing "radio waves" such as microwaves); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat or to synchronised molecular vibrations (the term 'heat', properly applies only to disordered molecular motion).
Patients may be awake during neurosurgery and asked to perform tasks, such as moving fingers or repeating words. This is necessary so that surgeons can remove the desired tissue while sparing other regions. Removing too much brain tissue can cause permanent damage, while removing too little can mandate additional neurosurgery. [citation needed]
In the brain, electrical signals are spread by the firing of neurons which lead to a desired outcome in the body. This can be caused by a release of a neurotransmitter or the voluntary contractions of a muscle. An action potential must be met in order for the electrical signal to be created. [1]
Amyloid beta (Aβ) was found to cause neurotoxicity and cell death in the brain when present in high concentrations. Aβ results from a mutation that occurs when protein chains are cut at the wrong locations, resulting in chains of different lengths that are unusable.
Mouse Brain Library [3] High resolution mouse brain atlas; BrainMaps. High-Resolution Brain Maps and Brain Atlases of Mus musculus; Despite superficial differences, especially in size and weight, the mouse brain and its function can serve as a powerful animal model for study of human brain diseases or mental disorders (see e.g. Reeler ...
In many protocols, mice are coinjected with pertussis toxin to break down the blood-brain barrier and allow immune cells access to the CNS tissue. This immunisation leads to multiple small disseminated lesions of demyelination (as well as micro-necroses) in the brain and spinal cord and the onset of clinical symptoms. [citation needed]
There exist studies on germ-free mice, devoid of any gut bacteria, that show the mice exhibit less anxiety compared to mice with a normal gut microbiome. [ 40 ] [ 41 ] Inflammations or infections of the gut tract of mice caused a change in certain behaviour associated with symptoms of anxiety, such as a less drive to explore [ 42 ] and a ...
Bioelectromagnetics, also known as bioelectromagnetism, is the study of the interaction between electromagnetic fields and biological entities. Areas of study include electromagnetic fields produced by living cells, tissues or organisms, the effects of man-made sources of electromagnetic fields like mobile phones, and the application of electromagnetic radiation toward therapies for the ...
