Extensive research on humans suggests that exercise could have benefits for overall health
and cognitive function, particularly in later life. Recent studies using animal models have …

“Is there a biology of intelligence which is characteristic of the normal human nervous
system?” Here we review 37 modern neuroimaging studies in an attempt to address this …

Chronic exposure to uncontrollable stress causes loss of spines and dendrites in the
prefrontal cortex (PFC), a recently evolved brain region that provides top-down regulation of …

Dendritic spines, which receive most of the excitatory synaptic input in the cerebral cortex,
are heterogeneous with regard to their structure, stability and function. Spines with large …

Mutations in MeCP2, which encodes a protein that has been proposed to function as a
global transcriptional repressor, are the cause of Rett syndrome (RT T), an X-linked …

Plasticity is a remarkable feature of the brain, allowing neuronal structure and function to
accommodate to patterns of electrical activity. One component of these long-term changes is …

Brain-derived neurotrophic factor (BDNF) has a central role in brain plasticity by mediating
changes in cortical thickness and synaptic density in response to physical activity and …

One of the most rigorously investigated problems in modern neuroscience is to decipher the
mechanisms by which experience-induced changes in the central nervous system are …

The decline observed during aging involves multiple factors that influence several systems.
It is the case for learning and memory processes which are severely reduced with aging. It is …

In order to guarantee better conditions for competition, the nervous system has developed
not only mechanisms controlling muscle effectors, but also retrograde systems that, starting …
