Abstract
Quantitative morphological and functional bases are given for an analog computer model of the frog cerebellar cortex. The model is based on actual neuronal counts and takes into consideration the three main types of neurons in the cerebellar cortex (Purkinje cells, granule cells, and stellate cells) and the two cerebellar afferent systems (mossy and climbing fibers). Physiologically the responses of mossy fibers and Purkinje cells are defined as observed following physiological stimulation of the vestibular system by means of rotative angular acceleration.

Brain modeling by tensor network theory and computer simulation. The cerebellum: distributed processor for predictive coordination.

TL;DR: In this article, it is shown that the firing frequencies of individual cells over a cerebellar cortical area may be interpreted as a spatially distributed, finite, series expansion of a time function, which is reconstructed, by summation, in the nucleus where the cortical cells project.

A computer model of cerebellar purkinje cells

TL;DR: It was shown that the electrophysiological parameters available in the literature make it possible to construct a model capable of demonstrating most of the electrical properties of Purkinje cells, such as antidromic invasion and the ability to generate simple spikes and spike bursts.

Vestibular habituation to angular velocity steps in the cat.

TL;DR: Vestibular habituation was investigated in 6 adult cats submitted to repetitive alternating velocity steps and the progressive change of the nystagmic response was examined by constructing diagrams of the slow cumulative eye position and slow phase eye velocity.

A computer model of the cerebellar cortex of the frog.

TL;DR: A computer simulation of the neuronal circuits in the cerebellar cortex of frog gives evidence for functional specificity in the absence of morphological specificity, suggesting that only a limited amount of genetic specificity may be necessary to generatefunctional specificity in certain neuronal circuits.

TL;DR: P-cell dendritic arbor is primitive in Fugu, being much less complex than inMus musculus and inHomo sapiens, and it is expected that a new generation of data mining tools will be required to support recursive fractal geometrical, combinatorial, and neural network models of the genomic basis of morphogenesis.

How we know universals: the perception of auditory and visual forms

TL;DR: Two neural mechanisms are described which exhibit recognition of forms which are independent of small perturbations at synapses of excitation, threshold, and synchrony, and are referred to partiular appropriate regions of the nervous system, thus suggesting experimental verification.

Is the Cerebellar Cortex a Biological Clock in the Millisecond Range

TL;DR: In any particular region of the cerebellar cortex, the ratio, volume, and number of afferent and efferent fibers is approximately constant, which can be deduced from measurements of the surface of the molecular layer in a certain region and the cross section of the corresponding white core.

Parallel fibre stimulation and the responses induced thereby in the Purkinje cells of the cerebellum.

TL;DR: Investigations by microelectrode recording established that this wave is produced by impulses propagating for at least 3 mm and at about 0.3 m/sec along a narrow superficial band or “beam” of parallel fibres, and there was an absolutely refractory period of less than 1 msec and impulse annihilation by collision.
