Normal brain functioning and cognition are thus clearly interlinked to the correct interplay between glia cells and neurotransmitters. The degeneration of the developing brain of this species of worm suggests that glia "listen in" on neuronal communication and act based on what the glia "hear" from the chemical messenger cells of neurotransmitters in a vitally important way (Chen 2009)
This stimulates brain activity, which can help to treat a variety of conditions, such as major depression. Research is currently underway to determine if magnetic fields may be useful in other neurological disorders as well (Fitzgerald, Fountain, & Daskalakis, 2006)

Weaknesses One of the key weaknesses of Neuronetics, Inc. is that the theory behind the machine has been accused of being unable to be proven according to modern clinical standards (Zwillich, 2007)
H. Kayser explains that "Exotoxins" are pathogenic bacteria that are capable of producing a "variety of toxins that are either the only pathogenic factor" in the onset of diseases like diphtheria, tetanus and cholera, or if they aren't the only factor they are at lease a "major factor" in a person getting these three diseases (Kayser, 2011)
Meanwhile in the book Neurobiology of Brain Disorders: Biological Basis of Neurological and Psychiatric Disorders, the authors explain that the release of toxins can have a negative impact on the human nervous system. In particular the authors mention the "Clostridium botulinus and tetani toxins, which are metalloproteases that inhibit synaptic vesicle release" (Zigmond, et al
