This quantitative Golgi study extends our investigation of relationships between cortical dendrite systems in humans and higher cognitive functions. [] Key Method Tissue was obtained from 20 neurologically normal right-handers: 10 males (Mage = 52.2) and 10 females (Mage = 47.8). Several independent variables were investigated: GENDER (male, female), HEMISPHERE (left, right), and EDUCATION (less than high school, high school, and university).
A quantitative dendritic analysis of wernicke's area in humans. I. Lifespan changes
TLDR
Age‐related increases and decreases in the basilar dendrites of supragranular pyramidal cells in human superior temporal gyrus of left and right hemispheres are examined in cortical dendritic neuropil.
Regional dendritic and spine variation in human cerebral cortex: a quantitative golgi study.
TLDR
Dendritic progression appears to reflect significant differences in the nature of cortical processing, with spine-dense neurons at hierarchically higher association levels integrating a broader range of synaptic input than those at lower cortical levels.
A quantitative dendritic analysis of four functionally distinct areas of human cerebral cortex
TLDR
Dendritic extent is suggested to be related to the functional capabilities of human cerebral cortex and the belief that learning and environment alter the morphology, physiology, and function of cerebral cortex has found support in documented differences between the cortices of rats raised in enriched and impoverished environments.
The morphology of supragranular pyramidal neurons in the human insular cortex: a quantitative Golgi study.
TLDR
Overall, the insula had spinier, but shorter neurons than did high integration cortices, and thus may represent a specialized type of heteromodal cortex, one that integrates crude multisensory information crucial to interoceptive processes.
Age and hemisphere effects on dendritic structure.
TLDR
There are hemispheric differences in the dendritic structure of the small pyramidal neurons of presumptive human speech cortex and its right hemisphere analogue, and generalized neuronal atrophy is a candidate process to explain the decline in cognition with age.
Regional Dendritic Variation in Neonatal Human Cortex: A Quantitative Golgi Study
TLDR
Regional dendritic patterns suggest that the developmental time course of basilar dendrite systems is heterochronous and is more protracted for supramodal BA10 than for primary or unimodal regions (BA4, BA3-1-2, BA18).
Life‐span dendritic and spine changes in areas 10 and 18 of human cortex: A quantitative golgi study
Dendritic neuropil is a sensitive indicator of the aging process and may exhibit regional cortical variations. The present study examined regional differences and age‐related changes in the basilar
Biphasic dendritic growth of dorsolateral prefrontal cortex associative neurons and early cognitive development
TLDR
A biphasic pattern of postnatal dendritic development, together with a second growth spurt at the age of 2-3 years, represents a unique feature of the associative layer IIIC magnopyramidal neurons in the human dorsolateral prefrontal cortex and it is proposed that these structural changes relate to rapid cognitive development during early childhood.
