  • Interesting fact: It is not possible to tickle yourself. The cerebellum, a part of the brain, warns the rest of the brain that you are about to tickle yourself. Since your brain knows this, it ignores the resulting sensation
    • n Cerebellum (Anat) The large lobe of the hind brain in front of and above the medulla; the little brain. It controls combined muscular action. See Brain.

    • n cerebellum The little brain or hind-brain of a vertebrate animal; a lobe of the brain developed on the dorsal side of the cerebrospinal axis, between the corpora quadrigemina in front and the medulla oblongata behind, and forming part of the roof of the fourth ventricle. The pons Varolii is the corresponding ventral portion of the cerebrospinal axis, and these two parts together are sometimes called the epencephalon. In man the cerebellum is a well-developed mass, having an average weight of about 5½ ounces, occupying the inferior occipital fossa, and separated from the posterior portions of the cerebral hemispheres above by the tentorium. A median portion or vermis and two lateral hemispheres are distinguished, and these are divided by transverse clefts into thin, closely packed laminæ. The cerebellum has three pairs of peduncles by which it is connected with the rest of the brain: the superior peduncles, which join it with the cerebrum; the middle peduncles, which pass down on either side to form the pons Varolii; and the Inferior peduncles or restiform bodies, which connect it with the medulla oblongata. The surface of the laminæ is of gray matter, while the interior is white, so that a section at right angles to the lamellæ presents a foliaceous appearance, which has received the name of arbor-vitæ. There are other masses of gray matter within, namely, the corpus dentatum, nucleus emboliformis, nucleus globosus, and nucleus fastigii. (See corpus and nucleus.) The cerebellum seems to he principally concerned with the coördination of voluntary movements. See cuts under brain and corpus.

Quality assessment for short oligonucleotide microarray data
We are looking at HU95 chips from two sample cohorts (a total of about 40 sub jects) in each of the brain regions anterior cingulate cortex, cerebellum, and dorsolateral prefrontal cortex.
Quality assessment for short oligonucleotide microarray data
While for cerebellum the quality in lab M is still better than in the replicate in one of the other labs, for the other two brain regions the ranking is reversed. Effects of a slight underexposure in lab M may now have become more visible.

In cerebellum, lab M still produced slightly higher quality hybridizations than lab I, while the ranking is reversed and more pronounced in anterior cingulate cortex.
