The human cerebellum is located at the base of the brain, with the large mass of the cerebrum above it, and the portion of the brainstem called the pons in front of it. It is separated from the overlying cerebrum by a layer of tough dura mater called the cerebellar tentorium; all of its connections with other parts of the brain travel through the pons.
The cerebellum (pl.: cerebella or cerebellums; Latin for "little brain") is a major feature of the hindbrain of all vertebrates.Although usually smaller than the cerebrum, in some animals such as the mormyrid fishes it may be as large as it or even larger. [1]
[9] [10] The brainstem, resembling a stalk, attaches to and leaves the cerebrum at the start of the midbrain area. The brainstem includes the midbrain, the pons, and the medulla oblongata. Behind the brainstem is the cerebellum (Latin: little brain). [7] The cerebrum, brainstem, cerebellum, and spinal cord are covered by three membranes called ...
The cerebellar peduncles are three paired bundles of fibres that connect the cerebellum to the brain stem. [1] Superior cerebellar peduncle is a paired structure of white matter that connects the cerebellum to the mid-brain. Middle cerebellar peduncles connect the cerebellum to the pons and are composed entirely of centripetal fibers.
Its lobes are linked through a circuit of neurons connecting to the vermis, the medial structure in the cerebellum. Extensions leave the base of the follucular's lobes which then connect to the spinal cord. The cerebellum, which houses the flocculus, is located in the back and at the base of the human brain, directly above the brainstem. [7]
UBCs function to amplify inputs from the vestibular ganglia and nuclei by spreading and prolonging excitation within the granular layer. [ 2 ] [ 7 ] They receive glutamatergic inputs on its dendritic brush from a single mossy fibre terminal in the form of a giant glutamatergic synapse and make glutamatergic synapses with granule cells and other ...

They ascend into the white matter of the cerebellum, where each axon branches to innervate granule cells in several cerebellar folia. In this case, the pathway is so named for a unique synapse formed by its projections, the mossy fiber rosette. Fine branches of the mossy fiber axons twist through the granule cell layer, and slight enlargements ...
