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 ...

The arbor vitae / ˌ ɑːr b ɔːr ˈ v aɪ t iː / (Latin for "tree of life") is the cerebellar white matter, so called for its branched, tree-like appearance.In some ways it more resembles a fern and is present in both cerebellar hemispheres. [1]
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.
Artificial cerebrospinal fluid (aCSF) is a buffer solution prepared with a composition representative of cerebrospinal fluid that is used experimentally to immerse isolated brains, brain slices, or exposed brain regions to supply oxygen, maintain osmolarity, and to buffer pH at biological levels.
When you have healthy sleep, the glymphatic system in your brain—which pumps out waste products—is more active and efficient, Winter explains. But on the flip side, when you have poor sleep ...
Brain activity slows down, muscles and bones strengthen, hormones regulate, and the immune system is supported. REM, stage 4. During REM sleep, your brain is almost as active as when you’re awake.
The supraoptic nucleus is an important "model system" in neuroscience. There are many reasons for this: Some technical advantages of working on the supraoptic nucleus are that the cell bodies are relatively large, the cells make exceptionally large amounts of their secretory products, and the nucleus is relatively homogeneous and easy to ...
