Figure 1From: A reliable method for intracranial electrode implantation and chronic electrical stimulation in the mouse brainIllustration of connecting pins and mounted electrodes. A, a schematic illustration of electrode mounting and an image of connecting pins and a bipolar electrode. B, a photograph of a subject implanted. C-D, images of adjacent brain sections collected from a mouse. The animal was euthanized 3 months after electrode implantation. Note the track of an implanted CA3 electrode (arrowed, C) and densely packed hippocampal neurons in the area near the implanted electrode and in the adjacent section (D). Calibrations: 5 mm in A and 1 mm in C-D.Back to article page
