Inhibition of neurons
WebbOne such circuit allows motor neurons to inhibit themselves—a phenomenon called recurrent inhibition. Recurrent inhibition is achieved with a neuron, the Renshaw cell, that inhibits the motor neuron that excites it (see Figure 3.11 ). The inhibitory effect of the Renshaw also extends to nearby motor neurons ( Baldissera, Hultborn, & Illert, 1981 ). WebbTo test this in neurons, erastin (0.5–8 µM) was applied to hippocampal HT22 neurons for 16 hours. In addition, cells were cultured with the autophagy inhibitor, 3-methyladenin (10 mM) and/or ferroptosis inhibitors, ferrostatin 1 (10–20 µM) or deferoxamine (10–200 µM) before exposure to erastin.
