It’s important to note that simply counting the number of neurons in an animal’s brain is not the only way to measure intelligence or cognitive abilities. Other factors, such as the complexity of neural connections and the ratio of brain size to body size, also play important roles in de...
When a person stops performing an activity, the neural networks for the activity fall into disuse and eventually may disappear. Differences in weight and size of a person's brain does not correlate with differences in mental ability. The adult human brain normally weighs from 1.0 to 1.5 kg (...

Recently, much attention has been paid to interpreting the mechanisms for memory formation in terms of brain connectivity and dynamics. Within the plethora of collective states a complex network can exhibit, we show that the phenomenon of Collective Almost Synchronisation (CAS), which describes a sta...

But brain imaging showed that the childrenwho benefited most had a larger hippocampus, a key memory area, and strongerneural(神经的) connections between the hippocampus and brain regions involvedin long-term memory and habit-building.This gives us clues about the memory systems the brain uses to...
Grafts of embryonic habenula or control optic tectal grafts were placed in the lateral ventricle or anterior chamber of the eye. Transplantation alters the location of the habenula as well as its neural and vascular connections. Three groups of hosts were used for the ventricular grafts: four-...
Reading Notes of The Number Sense1. The essence of symbolic knowledge.A symbol, beyond its arbitrary shape, refers to a covert meaning. Symbol comprehension implies accessing this meaning from shape alone, while symbol production requires recovering the arbitrary shape from knowledge of the intended ...
ASD has attracted a great deal of attention of basic and clinical scientists in the hope that clarification of its underlying mechanisms will lead to the development of remedies for ASD as well as a better understanding of the neural substrates of important cognitive functions, including social ...
Determinants of hippocampal volume in MDD are not known. Like others (Reif et al, 2006), we did not detect fewer mitotic cells (Boldrini et al, 2009) or neural progenitor cells (NPCs) in the DG postmortem (Boldrini et al, 2009, 2012) in untreated MDD subjects (o58–60 y old) ...
