Pyramidal Tract: a Comparison of Two Prosimian Primates.

Pyramidal neurons of granular prefrontal cortex of the galago: complexity in evolution of the psychic cell in primates.

Typically, cognitive abilities of humans have been attributed to their greatly expanded cortical mantle, granular prefrontal cortex (gPFC) in particular. Recently we have demonstrated systematic differences in microstructure of gPFC in different species. Specifically, pyramidal cells in adult human gPFC are considerably more spinous than those in the gPFC of the macaque monkey, which are more s...

Prosimian Primates Show Ratio Dependence in Spontaneous Quantity Discriminations

We directly tested the predictions of the approximate number system (ANS) and the object file system in the spontaneous numerical judgments of prosimian primates. Prior work indicates that when human infants and a few species of non-human animals are given a single-trial choice between two sequentially baited buckets they choose the bucket with the greater amount of food but only when the quant...

A Study of Leaping in Prosimian Primates

Spasticity and the Human Pyramidal Tracts

After a long and tortuous history spanning over a century of clinicoanatomical and experimental observations, the concept of spasticity has assumed its current form as a velocity-dependent increase of tone in a group of passively stretched muscles. However, several gaps have remained in the understanding of spasticity as a clinical and experimental phenomenon. A long-standing controversy concer...

Comparison the Effect of Eight Weeks Pyramid Resistance Training With two Patterns on Bio-motor Ability and Anthropometrical in Wrestlers

Objective: Wrestling is a fast-paced activity in which resistance training is essential to improve athlete performance. We evaluated the effect of comparison of the effect of eight weeks resistance training with two patterns of pyramidal and inverse pyramidal on bio-motor ability, Anthropometrical and skill profile of freestyle wrestlers. Methods: In this semi experimental study, 24 male frees...
