Sex and age were the main determinants of the total number of neurons in the human neocortex, whereas body size, per se, had no influence on neuron number. Some of the data presented have been analyzed by using new mathematical designs. An equation predicting the total neocortical neuron ...
Despite a general trend for larger mammals to have larger brains, humans are the primates with the largest brain and number of neurons, but not the largest body mass. Why are great apes, the largest primates, not also those endowed with the largest brains? Recently, we showed that the ener...
7. Yet in order to learn something, one must not be too prejudiced.没有成见地去学习一项新事物。8.The total number of neurons remains constant , the growth of the numerical network must occur at the expen
This paper studies the cell size-dependent organization of the nucleolus and Cajal bodies (CBs) in dissociated human dorsal root ganglia (DRG) neurons from autopsy tissue samples of patients without neurological disease. The quantitative analysis of nucleoli with an anti-fibrillarin antibody showed that...
of an ambitious computer simulation that the team designed to understand the behavior of the networks of hundreds of thousands of neurons that initiate different body movements: specifically, how the neurons are coordinated to trigger a movement at a particular point in time, called the response ...
Metabolic constraint imposes tradeoff between body size and number of brain neurons in human evolution(代谢限制在人类进化过程中身体大小与脑神经元数量之间的权衡).pdf,Metabolic constraint imposes tradeoff between body size and number of brain neurons in
from Chapter 28 / Lesson 1 67K Learn about human bone anatomy, including the function of bones and the functions of the skeleton. Discover how many bones are in the human skeleton, the structure of the human skeleton, and the types of bones in t...
Reported values in the literature on the number of cells in the body differ by orders of magnitude and are very seldom supported by any measurements or calculations. Here, we integrate the most up-to-date information on the number of human and bacterial cells in the body. We estimate the ...
