Immerse a block (approx. 10x5 mm) of formaldehyde-fixed (or paraformaldehyde- glutaraldehyde-perfused) brain tissue into a 2% aqueous solution of potassium dichromate for 2 days; Dry the block shortly with filter paper. Immerse the block into a 2% aqueous solution of silver nitrate for another 2 days. Cut sections approx. 20–100 μm thick.
The slice preparation or brain slice is a laboratory technique in electrophysiology that allows the study of neurons from various brain regions in isolation from the rest of the brain, in an ex-vivo condition. Brain tissue is initially sliced via a tissue slicer then immersed in artificial cerebrospinal fluid (aCSF) for stimulation and/or ...
It is believed to play a role in some cases of human epilepsy. [7] [8]It has also been implicated in working memory [9] and drug addiction. [10]It has been suggested that the dorsal subiculum is involved in spatial relations, and the ventral subiculum regulates the hypothalamic-pituitary-adrenal axis.
In Ogawa's experiments, blood-oxygen-level-dependent imaging of rodent brain slice contrast in different components of the air. At high magnetic fields, water proton magnetic resonance images of brains of live mice and rats under anesthetization have been measured by a gradient echo pulse sequence.
The dentate gyrus (DG) is part of the hippocampal formation in the temporal lobe of the brain, which also includes the hippocampus and the subiculum.The dentate gyrus is part of the hippocampal trisynaptic circuit and is thought to contribute to the formation of new episodic memories, [1] [2] the spontaneous exploration of novel environments [2] and other functions.
