Mirror neurons: a definition. Description: Professor Christian Keysers explains that mirror neurons in the premotor cortex respond when we perform an action and also when we see someone else perform that action. This is similar to empathy. Transcript: Mirror neurons are a set of neurons that we discovered in the premotor cortex of the monkey.
lectin. [ 1 lekâ²tin] 2  a protein in seeds and other parts of certain plants that binds with glycoproteins and glycolipids on the surface of animal cells, causing agglutination. Some lectins agglutinate erythrocytes in specific blood groups, and others stimulate the production of T lymphocytes.
Lectin intolerance means the inability to deactivate the toxic lectin (prevent its binding to your cells) in the confines of your own body, be it in the gut, artery, organ, gland or brain. The lectin then proceeds to invoke immune responses that damage the cell to which it attaches and possibly surrounding cells.
