The brain

Area of Science:

  • Neuroimmunology
  • Cerebral Cortex Function
  • Mammalian Physiology

Background:

  • The cerebral neocortex plays a role in regulating the immune system.
  • Previous studies suggested potential sex-based differences in brain-immune interactions.

Purpose of the Study:

  • To investigate the influence of specific cerebral neocortex regions on immune responses.
  • To determine if immune function lateralization exists in the brain cortex.

Main Methods:

  • Lesioning of the right or left fronto-parietal cortex in male Wistar rats.
  • Assessing T-lymphocyte mitogenesis using phytohemagglutinin and Urtica Dioca Agglutinin.
  • Measuring antibody synthesis and plasma levels of ACTH and prolactin.

Main Results:

Related Experiment Videos

  • Left cortical lesions decreased T-lymphocyte mitogenesis by 25-40%.
  • Right cortical lesions increased T-lymphocyte mitogenesis by 20-45%.
  • No significant changes in antibody synthesis or hormone levels were observed.

Conclusions:

  • Evidence suggests lateralization of immunomodulatory functions in the brain cortex.
  • These findings may be conserved across sexes and mammalian species.
