Most vertebrate species have a cerebellum and one or more cerebellum-like structures, brain areas that resemble the cerebellum in terms of cytoarchitecture and neurochemistry. [81] The only cerebellum-like structure found in mammals is the dorsal cochlear nucleus (DCN), one of the two primary sensory nuclei that receive input directly from the ...
Cerebellar cognitive affective syndrome (CCAS), also called Schmahmann's syndrome [1] is a condition that follows from lesions (damage) to the cerebellum of the brain. It refers to a constellation of deficits in the cognitive domains of executive function, spatial cognition, language, and affect resulting from damage to the cerebellum.
Non-invasive cerebellar stimulation is the application of non-invasive neurostimulation techniques on the cerebellum to modify its electrical activity. Techniques such as transcranial magnetic stimulation (TMS) or transcranial direct current stimulation (tDCS) can be used. [ 1 ]
The cerebellum is divided into an anterior lobe, a posterior lobe, and the flocculonodular lobe. [32] The anterior and posterior lobes are connected in the middle by the vermis. [33] Compared to the cerebral cortex, the cerebellum has a much thinner outer cortex that is narrowly furrowed into numerous curved transverse fissures. [33]
This separation makes sense if the cerebellum, which is far removed from the hippocampus, is responsible for procedural learning. The cerebellum is more generally involved in motor learning, and damage to it can result in problems with movement, specifically it is considered to co-ordinate timing and accuracy of movements, and to make long-term ...
This approach, targeting the cerebellum, though successful, examines only basic, automatic responses, which virtually all animals possess. However, engrams of specific types of memory are found in the subsystems mediating that learning process [ citation needed ] and as such solely engrams of simple conditioning are associated with the LIP but ...
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.
Two cerebellar sites of CS-US convergence are 1) cells of the deep nuclear region in the cerebellum, and 2) PCs of the cortex. [6] In addition to receiving converging CS and US input via the PN and IO, respectively, cells of the cerebellar nuclei receive GABA -ergic inhibitory input from PCs of the cerebellar cortex.
