Abstract
Here we summarize topics covered in an
SFN symposium that considered how and why exercise and energy intake
affect neuroplasticity
and, conversely, how the brain regulates
peripheral energy metabolism. This article is not a comprehensive review
of the subject,
but rather a view of how the authors' findings
fit into a broader context. Emerging findings elucidate cellular and
molecular
mechanisms by which exercise and energy intake
modify the plasticity of neural circuits in ways that affect brain
health.
By enhancing neurogenesis, synaptic plasticity
and neuronal stress robustness, exercise and intermittent energy
restriction/fasting
may optimize brain function and forestall
metabolic and neurodegenerative diseases. Moreover, brain-centered
glucoregulatory
and immunomodulating systems that mediate
peripheral health benefits of intermittent energetic challenges have
recently been
described. A better understanding of adaptive
neural response pathways activated by energet
