Could Pulsed Electronically Generated Electromagnetic Fields Cause Alzheimer’s?

Pulsed electronically generated electromagnetic fields (EMFs) used for wireless communications produce electric and magnetic forces that act in the body's cells by activating voltage-gated calcium channels (VGCCs). VGCC activation induces changes that increase intracellular calcium levels. Researchers link EMF exposure to changes that lead to excessive intracellular calcium. This could have implications for the development of Alzheimer's disease.

Age and Alzheimer’s Related Brain Decline Linked to Little-Studied Enzyme

The HDAC9 enzyme appears to play a critical role in learning and neural communication. Decreased expression of HDAC9 in the hippocampus and prefrontal cortex has been noted in patients with Alzheimer's disease. Researchers say HDAC9 may be a regulator of synaptic plasticity.

Memory Is Formed Through Rewiring of Global Network Among Pre-existing Local Neuronal Ensembles

Information about new experiences is retained by being tied to pre-existing activity patterns in the brain. Memory is acquired when the patterns are connected to each other across brain regions via transient bursts of activity.
