A standard test of cerebellar function is to reach with the tip of the finger for a target at arm's length: A healthy person will move the fingertip in a rapid straight trajectory, whereas a person with cerebellar damage will reach slowly and erratically, with many mid-course corrections. Deficits in non-motor functions are more difficult to ...
The cerebellum's anterior and posterior lobes appear to play a role in the coordination and smoothing of complex motor movements, and the flocculonodular lobe in the maintenance of balance [36] although debate exists as to its cognitive, behavioural and motor functions.
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 (Latin for “little brain”) is a distinct part of your brain that is attached to the rest of your brain at the back of your head. The cerebellum is only about one-tenth the size ...
Cerebellum – Cerebellum has many uses. Has a very important role in emotion perception and emotion attributions. [34] Cerebellar dysfunction has been shown to decrease positive emotions during lesion studies. [35] Over the course of evolution, the cerebellum may have evolved into a circuit that helps reduce fear in order to enhance survival.
A rare brain disease of the cerebellum is rhombencephalosynapsis characterized by an absent or partially formed vermis. Symptoms can include truncal ataxia. The disorder is a main feature of Gomez-Lopez-Hernandez syndrome.
The occipital lobe sits directly above the cerebellum and is situated posterior to the Parieto-occipital sulcus, or parieto-occipital sulcus. [22] This lobe is known as the centre of the visual perception system, the main function of the occipital lobe is that of vision.
The main area involved in motor learning is the cerebellum. Some models of cerebellar-dependent motor learning, in particular the Marr-Albus model, propose a single plasticity mechanism involving the cerebellar long-term depression (LTD) of the parallel fiber synapses onto Purkinje cells.
