From cerebellar texture to movement optimization
- BiologyBiological Cybernetics
The aim of this review was to link the distinctive functions of the cerebellum, as derived from cerebellar lesion studies, with potential elementary computations, as observed by a bottom-up approach from the Cerebellar microcircuitry.
AGE RELATED CHANGES IN THE PURKINJE CELLS IN HUMAN CEREBELLAR CORTEX
The results of the study showed that the Purkinje cells are seen as a linear interface at the junction of the molecular and granular layer in the human cerebellum.
The Morpho/Functional Discrepancy in the Cerebellar Cortex: Looks Alone are Deceptive
- BiologyFront. Neurosci.
A discrepancy between anatomical structure and functional dynamics is highlighted and a plausible underlying mechanism is suggested that could explain this arrangement of activity.
The length of parallel fibers in the cat cerebellar cortex. An experimental light and electron microscopic study
- BiologyExperimental Brain Research
The studies suggest that in folia longer than 7 mm parallel fibers are 6 mm long on the average, and it was determined on Golgi sections that the average center-to-center distance between en passant boutons of individual parallel fibers is 5.2 μm.
The connectivity of the brain: multi-level quantitative analysis
- BiologyBiological Cybernetics
A mathematical formalism or calculating connectivity volumes generated by specific topologies with various physical packing strategies is developed and it is concluded that interior packing is less efficient than exterior packing (in a sphere) and fully and randomly connected topologies are extremely inefficient.
Detectability of cerebellar activity with magnetoencephalography and electroencephalography
- Biology, PsychologyHuman brain mapping
The results show that cerebellar activity should be clearly detectable by current M/EEG systems with an appropriate experimental setup.
A model for time interval learning in the Purkinje cell
A biologically plausible model is proposed which complements the modification of synaptic weights for learning one time interval in one synapse of one Purkinje cell and discusses how this model would allow the cerebellum to detect and generate specific spatio-temporal patterns, a classical theory for cerebellar function.
The cerebellum for jocks and nerds alike
- Biology, PsychologyFront. Syst. Neurosci.
The results from studying how Purkinje cells encode movement signals suggest that the cerebellar cortex circuitry can support associative learning, sequencing, working memory, and forward internal models in non-motor domains.
Congenital hypoplasia of the cerebellum: developmental causes and behavioral consequences
- BiologyFront. Neuroanat.
The role of the midbrain hindbrain isthmic organizer in the development of the cerebellar vermis and the specification and differentiation of Purkinje cells and granule neurons are discussed.
Sensorimotor mapping of the human cerebellum: fMRI evidence of somatotopic organization
- BiologyHuman brain mapping
Functional magnetic resonance imaging was employed to determine areas of activation in the cerebellar cortex in 46 human subjects during a series of motor tasks and representations were observed that seem to confirm earlier electrophysiological findings of sagittal zones in animals.

THE CEREBELLUM: A REVIEW AND INTERPRETATION
Detailed studies of the comparative anatomic relations and development, phylogenetic and ontogenetic, of the cerebellum in mammals and submammals have thrown new light on the functional connections…
THE MAMMALIAN CEREBELLUM: A COMPARATIVE STUDY OF THE ARBOR VITAE AND FOLIAL PATTERN
In order that definite conclusions may be reached in regard to functional localization within the cerebellum on the basis of the characteristics of the folial pattern as compared with the physical organization of the animal providing the pattern, a much greater number of cerebella must be studied.
THE EVOLUTION AND ANATOMY OF THE CEREBELLUM
The identification of all lateral cerebellar parts with the neocerebellum seems hardly justified when the authors realize that both ontogenetically and phylogenetically the cerebellum had a bilateral origin, and that even in man one of the lateral parts, the flocculus, appears very early in the development of the Cerebellum.
