 The Covid-19 pandemic has caused significant changes in the way we live our lives. In particular, it has been found that the virus can affect the brain's ability to produce certain neurotransmitters such as glutamate and GABA. This can lead to a variety of mental health issues including anxiety and impaired cognition. A mathematical model was developed to study how these changes in neurotransmitter production could affect the brain's ability to generate coherent bursting discharges. The model suggests that when glutamate levels are reduced, the brain's ability to generate coherent bursting discharges is severely compromised. Additionally, the model shows that this effect can be intermittent with periods of normal rhythm followed by complete loss of synchronicity.
