Design-based estimation of neuronal number and individual neuronal volume in the rat hippocampus
Journal of Neuroscience Methods, 2007Tools recently developed in stereology were employed for unbiased estimation of the neuronal number and volume in three major subdivisions of rat hippocampus (dentate granular, CA1 and CA3 pyramidal layers). The optical fractionator is used extensively in quantitative studies of the hippocampus; however, the classical optical fractionator design may be

THE NUMBERS OF NEURONES IN DECAPOD CRUSTACEA
Journal of Crustacean Biology, 1988THE NUMBERS OF NEURONES IN CRUSTACEA Details regarding the nervous system of Crustacea rest heavily on the larger Decapoda. Investigations into the arrangements in all the other groups and of larval stages are few and far between. In many ways this is understandable, for the larger adult decapods are much more amenable to physiological work and it is ...

Unbiased number of vestibular ganglion neurons in the mouse
Neuroscience Letters, 1998Vestibular sensory information from the labyrinth and otolith organs is conducted to the central nervous system exclusively via primary vestibular afferents (PVA) originating from neurons located in the vestibular ganglion (VG). In the present study, the total number of VG neurons was determined in two different wild-type mouse strains using the ...

Number faculty is alive and kicking: On number discriminations and number neurons
Behavioral and Brain Sciences, 2017AbstractLeibovich et al. advocate for a single “sense of magnitude” to which a dedicated faculty for number could allegedly be reduced. This conclusion is unjustified as the authors adopt an unnecessarily narrow definition of “number sense,” neglect studies that demonstrate non-symbolic numerosity representation, and furthermore ignore abstract number ...

Fall in the number of intracardiac neurons in aging rats
Mechanisms of Ageing and Development, 1999The neurons of whole cardiac atria were stained using a NADH-diaphorase technique in young adult (3 months old) (GI) and aging rats (20 months old) (GII). Light microscopy revealed differences in the appearance of the neurons in the two groups. In GI, most ganglia contained 50-100 neurons while in GII, most ganglia usually contained 20 neurons.

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 ...
