Parkinson's disease (PD), characterized by the absence of dopamine in the striatum[1], is caused by the death of the substantia nigra pars compacta dopamine (SNcDA) neurons in the mid-brain. The cause of this cell loss is attributed to irreparable damage due to a dysregulation cascade originating from excess cytosolic dopamine[2]. However, it is unresolved if dopamine dysregulation in SNcDA neurons themselves is the cause of PD or if it is a mere symptom. Here, we introduce a theory of specialized non-causal action potentials that serve metabolic homeostasis called `metabolic spikes' which can

Aims. Acute consumption of sweeteners has become increasingly common in modern diets. However, emerging research suggests that the impact of sweeteners on the hypothalamus, involved in regulating food intake [CA1] and metabolism, may be deleterious. Several studies have raised concerns about their potential effects on brain cellular metabolism (Kohno D et al.,2016), suggesting a mismatch between detection of false sugar and the energy value actually detected. This study aimed to investigate the dose-dependent impact of sweeteners on these energetic processes. Methods. Using the hypothalamic ce
