Brain connectivity

Morphology and function

These data were acquired using a BioSpec® 47/40V.

Intravitreal and cortical MnCl2 injection allows the determination of projections and connectivities in the monkey brain. Mn2+ acts as an MRI contrast agent and is actively transported along fibers and axons.
 
A, B is the tracer (green) in the visual system (retina, nerve, tract, LGN, radiation in the visual cortex), projections to substantia nigra after caudate
injection (C) and to the Globus Pallidus (D, with HRP histology).
