The Impact of Mobile Phone Electromagnetic Waves on the Neurons and Blood Brain Barrier Integrity in the Chick Embryo

Abstract

Category: Neuroscience Tags: electromagnetic fields, mobile phones, chick embryo, blood-brain barrier, neuronal damage, apoptosis, wireless technology URL: biomedpharmajournal.org Overview With the rapid increase of Wi-Fi, Bluetooth, and other wireless technologies, the electromagnetic environment in everyday life has significantly changed. Mobile phones, a source of non-ionizing low-frequency electromagnetic waves (EW), are omnipresent. This study investigates the effects of mobile phone EW on the developing brain of chick embryos. Methods - Fertilized eggs were incubated under two conditions: one group exposed to electromagnetic waves from a mobile phone and one control group without exposure. - A mobile phone was called from outside the incubator on a set schedule for the exposed group (20 eggs each group). - Embryos were sacrificed on days 10 and 15 for electron microscopy analysis of the cerebral cortex and cerebellum. Findings - Control Group: Cerebral neurons exhibited healthy and normal features, including a large, centrally placed nucleus, visible oligodendrocytes, and a less dense extracellular matrix. The blood-brain barrier remained intact. - Exposed Group: Cerebral neurons were fewer in number, smaller, showed unclear nuclear margins, shrinkage, signs of apoptosis (cell death), and a dense extracellular matrix. In the cerebellum, a reduced number of Purkinje neurons and significant mitochondrial swelling were observed. - The blood-brain barrier was compromised in the exposed embryos, clearly linking EMF exposure to biological effects on brain integrity and development. Conclusion The study demonstrates that electromagnetic waves emitted by mobile phones adversely affect the normal brain development and blood-brain barrier integrity in chick embryos, a clear health risk associated with electromagnetic field exposure.

Main findings

Compared with controls, embryos exposed to mobile phone electromagnetic waves showed fewer and smaller cerebral neurons with unclear nuclear margins, shrinkage and signs of apoptosis, and a denser extracellular matrix. Exposed embryos also showed reduced Purkinje neuron numbers with mitochondrial swelling, and the blood-brain barrier was reported as compromised.

Outcomes measured

• Neuronal morphology/ultrastructure in cerebral cortex
• Neuronal morphology/ultrastructure in cerebellum (Purkinje neurons, mitochondria)
• Apoptosis-related neuronal changes
• Blood-brain barrier integrity

Limitations

• Frequency/band and SAR or field strength not reported in the abstract
• Exposure schedule details not specified in the abstract
• Small sample size (20 eggs per group)
• Outcomes appear based on electron microscopy morphology; functional/behavioral outcomes not described

Suggested hubs

• mobile-phones (0.9)
  Exposure source is a mobile phone; study examines biological effects of mobile phone electromagnetic waves.
