Hormones are important messages both within the brain and between the brain and the body.
  • BrainFacts/SfN
The messages sent from one brain cell to another are the basis of brain function. Brain cells communicate through both electrical and chemical means.
  • BrainFacts/SfN
Insulation covering wires preserves the strength of the electrical signals that travel through them. The myelin sheath covering axons serves a similar purpose.
  • BrainFacts/SfN
Chemical reactions within brain cells translate the neurotransmitter message for the neuron.
  • BrainFacts/SfN
Molecules that are important in brain development may help treat or prevent brain injuries and disorders.
  • BrainFacts/SfN
In response to signals from a brain region called the hypothalamus, the adrenal glands secrete glucocorticoids, hormones that produce an array of effects in response to stress.
  • BrainFacts/SfN
A stressful situation activates three major communication systems in the brain, all of which regulate bodily functions.
