Commissural axon guidance requires complex modulations of growth cone sensitivity to midline-derived cues, but underlying mechanisms in vertebrates remain largely unknown. By using combinations of ex vivo and in vivo approaches, we uncovered a molecular pathway controlling the gain of response to a midline repellent, Semaphorin3B (Sema3B). First, we provide(More)
γ-Aminobutyric acid (GABA) is a kind of amino acid contained in green tea leaves and other foods. Several reports have shown that GABA might affect brain protein synthesis, improve many brain functions such as memory and study capability, lower the blood pressure of spontaneously hypertensive rats, and may also have a relaxation effect in humans. However,(More)
Propofol, an intravenous general anaesthetic, exerts anaesthetic actions through interaction with gamma-aminobutyric acid type A (GABA(A)) receptors in the supraspinal nervous system. However, whether propofol has any significant effects on synaptic transmission at the spinal level and whether it exhibits antinociceptive action is still not fully clarified.(More)
