On the role of anatomy in learning by the cerebellar cortex

Mathematical Biosciences, 1999
The properties due to the location of neurons, synapses, and possibly even synaptic channels, in neuron networks are still unknown. Our preliminary results suggest that not only the interconnections but also the relative positions of the different elements in the network are of importance in the learning process in the cerebellar cortex.

Cerebellar Cortex

2010
The microcircuit in the cerebellum is characterized by the relative simplicity, precision, and geometric beauty of its arrangement. Its structure is identical throughout the cerebellar cortex except for some regional differences. The cerebellar cortex has three layers (molecular layer, Purkinje cell layer, and granular layer) and can be divided into ...

Zones in the cerebellar cortex

Journal of Neurosurgery, 1981
✓ The organization of zones in the cerebellar cortex, as reflected by the arrangement of cortical efferent and afferent fibers, was reviewed with special emphasis on the anterior lobe. There is conclusive evidence for the existence of at least six, and possibly as many as nine, ipsilateral rostrocaudally oriented cortical zones, each having specific ...

Pharmacological properties of inhibitions in the cerebellar cortex

Experimental Brain Research, 1971
Stimulation of the parallel fibres, or the mossy fibres, in the cerebellar cortex depresses the potential generated in the granular layer by anti-dromic invasion of the Purkinje cells (N1), and that generated by the axon discharge of granule cells (P2).

Retrograde endocannabinoid signaling in the cerebellar cortex

The Cerebellum, 2006
The regulation of Purkinje cell activity is important for motor behavior and motor learning. As the sole output cell of the cerebellar cortex, Purkinje cell firing is controlled by parallel fibers and climbing fiber synapses, and by inhibitory interneurons.

A computer model of the cerebellar cortex of the frog

Neuroscience, 1977
Abstract A computer simulation of the neuronal circuits in the cerebellar cortex of frog is developed as a means of testing the functional properties of this cortex. The model is based on present day information regarding morphology and function of the different cortical neurons.

Sarcoglycans in cerebellar cortex: an immunohistochemical study

Italian Journal of Anatomy and Embryology, 2011
Sarcoglycans are transmembrane glycoproteins which link each others to form the sarcoglycans sub-complex. This protein system plays a key role in fibers stabilization during muscle activity. Sarcoglycans have been mainly studied on muscle tissue but they aren’t muscle specific.

Neurotrophic effects of PACAP in the cerebellar cortex

Peptides, 2007
In the rodent cerebellum, PACAP is expressed by Purkinje neurons and PAC1 receptors are present on granule cells during both the development period and in adulthood. Treatment of granule neurons with PACAP inhibits proliferation, slows migration, promotes survival and induces differentiation.

Cerebellar cortex and eyeblink conditioning: A reexamination

Experimental Brain Research, 1992
We examined the effects of cerebellar cortical lesions upon conditioned nictitating membrane responses in rabbits. Using extended postoperative conditioning and unpaired presentations of the conditioned stimuli (CSs), we confirmed that combined lesions of lobules HVI and ansiform lobe abolished conditioned responses (CRs) established to light and white

Dysplasias of Cerebellar Cortex

1975
The following remarks amplify the basic aspects of normal cerebellar cortical development described in Chapter 1 and may help the understanding of developmental derangements in cortical architecture. Labelling with tritiated thymidine has shown that the Purkinje cells and the cells of the cerebellar nuclei originate from the division of precursors in ...
