An international research team including scientists from Leibniz IPHT (Jena,Germany; www.leibniz-ipht.de) has created an ultra-thin endo-microscope that offers gentle in-depth observations,enabling detailed investigation of the brain. 

The endoscope has a diameter of only 110micrometers, making it about as thin as a human hair. This slim structure allows the device to capture images deep within tissues and at a subcellular level. 

This innovation could potentially help in studying the onset and progression of severe neuronal diseases,providing new insight for neuroscientists to formulate strategies against these debilitating conditions.
