Afferent control of neuron numbers in the developing brain
Developmental Brain Research, 1988In this study we tested whether the quantitative matching of developing neuronal populations may depend on the size of the afferent supply. Partial deafferentation of the middle division of the parabigeminal nucleus (PBm) was produced before the period of naturally occurring cell death, by reducing the neuronal population of the superior colliculus ...

Regulating the number and function of neuronal acetylcholine receptors
Trends in Neurosciences, 1989Nicotinic acetylcholine receptors (AChRs) on vertebrate neurons represent a family of receptors distinct from the well-characterized AChR of skeletal muscle. New probes for neuronal AChRs are now being used to examine the regulation of receptor number and function.

Increased Neuron Number and Head Size in Autism
JAMA, 2011N THIS ISSUE OF JAMA, THE REPORT BY COURCHESNE AND colleagues 1 documents an increase in neuron number intheprefrontalcortex(PFC)inmalechildrenandadolescents with autism. Those findings build on Leo Kanner’s original observations 2 in 1943 and 2 decades of recent research investigating macrocephaly in autism.

Nutritional effects on neuron numbers.
Nutritional neuroscience, 2003Undernutrition during early life is known to cause deficits and distortions of brain structure although it has remained uncertain whether or not this includes a diminution of the total numbers of neurons. Estimates of numerical density (e.g. number of cells per microscopic field, or number of cells per unit area of section, or number of cells per unit ...

Morphology and number of neurons in two species of polychaetes
Journal of Comparative Neurology, 1981AbstractNeurons of the ventral nerve cord (VNC) in the polychaete species Clymenella torquata and Nereis virens were ultrastructurally distinguished from glial cells by the smaller diameter and elongated shape of glial nuclei in adult organisms. In contrast to neurons, ß‐glycogen‐like particles and densely packed microfilaments were found in glial ...

Neurons, numbers and the hippocampal network.
Progress in brain research, 1990Anatomists involved with studies of the hippocampal formation are being prodded by computational modelers and physiologists who demand detailed and quantitative information concerning hippocampal neurons and circuits. The beautiful camera lucida drawings of old, and the elegant descriptions of dendritic form that accompanied them are giving way to ...

Cranial capacity and neuron number: A critique and proposal
American Journal of Physical Anthropology, 1966AbstractSome recent studies correlating cranial capacity with behavioral development and more molecular parameters such as neuron number are critically examined. These studies are found lacking in terms of basic assumptions and empirical support from other studies.
