Jul 27, 2023 · Anatomically, the cerebellum consists of the anterior lobe (anterior to the primary fissure), the posterior lobe (posterior to the primary fissure), and the flocculonodular lobe (below the posterior fissure). The cerebellum is located in the posterior cranial fossa of the cranial vault.

Let's start with the efferent pathways. The Dentate nucleus is the largest of the deep cerebellar nuclei and deals with information processed by the neocerebellum and sends its infomation to …

May 10, 2020 · An overview of the gross anatomy of the cerebellum, the functional regions of the cerebellum and some of the associated central nervous system pathways, including a narrated 3D tutorial.

Oct 30, 2023 · Deep to the molecular layer is the Purkinje cell layer. It is the sole efferent pathway from the cerebellum and provides inhibitory impulses to both the vestibular and cerebellar nuclei. The Purkinje cells are excited by climbing fibers of the inferior olivary nucleus and parallel fibers of the granule cells.

In most models of cerebellum function, the climbing fibers regulate movement by modulating the effectiveness of the mossy—parallel fiber connection with the Purkinje cells. The Purkinje cells project in turn to the deep cerebellar nuclei. They are the only output cells of the cerebellar cortex.

From the phylogenetically oldest to the newest, the three parts are: The vestibulocerebellum regulates balance and eye movements. It receives vestibular input from both the semicircular canals and from the vestibular nuclei, and sends fibres back to …

Jul 25, 2023 · The cerebellum, meaning "little brain" in Latin, is primarily responsible for the coordination of movement, maintaining posture and balance, muscle tone, and motor learning. Recent research has shown that the cerebellum may also have cognitive functions, but the exact mechanism and pathways are still unclear.

The cerebellum (“little brain”) is a structure that is located at the back of the brain, underlying the occipital and temporal lobes of the cerebral cortex (Figure 5.1). Although the cerebellum accounts for approximately 10% of the brain’s volume, it contains …

Direct spino-cerebellar pathways are indicated in green: the ventral spino-cerebellar tract (VSCT) and dorsal spino-cerebellar tract (DSCT) originate in thoracic and lumbar segments; the rostral spino-cerebellar tract (RSCT) originates in cervical segments; the cuneo-cerebellar tract (CCT) originates in the brainstem.

Major Components of the Cerebellum. The connections between the cerebellum and other parts of the nervous system occur by way of three large pathways called cerebellar peduncles (Figures 19.1 to 19.3). The superior cerebellar peduncle (or brachium conjunctivum) is almost entirely an efferent pathway.
