 Context examples 

Phenytoin sodium promotes sodium efflux from neurons located in the motor cortex, thereby stabilizing the neuron and inhibiting synaptic transmission.

(Phenytoin sodium, NCI Thesaurus)

This inhibits neuronal firing and results in the stabilization of neuronal membranes, thereby preventing the spread of seizure activity at the motor cortex.

(Ethotoin, NCI Thesaurus)

Phenytoin potentially acts by promoting sodium efflux from neurons located in the motor cortex reducing post-tetanic potentiation at synapses.

(Phenytoin, NCI Thesaurus)

Phenytoin exerts its effect most likely through an enhancement of sodium efflux from neurons in the motor cortex.

(Fosphenytoin Sodium, NCI Thesaurus)

Experts published a research that suggests the human propensity for contagious yawning is triggered automatically by primitive reflexes in the primary motor cortex - an area of the brain responsible for motor function.

(Why Is Yawning so Contagious?, The Titi Tudorancea Bulletin)

Although the mechanism of action is not well established, mephenytoin potentially promotes sodium efflux from neurons in motor cortex, and stabilizes the threshold against hyperexcitability caused by excessive stimulation.

(Mephenytoin, NCI Thesaurus)

The central sulcus separates the primary somatosensory cortex from the primary motor cortex and the frontal lobe from the parietal lobe.

(Fissure of Rolando, NCI Thesaurus)

The frequency of attacks is reduced by depression of nerve transmission in the motor cortex and elevation of the threshold of the CNS to convulsive stimuli, probably due to direct modification of membrane function in excitable cells and/or alteration of chemically mediated neurotransmission.
