    communicate with thousands of other neurons in complex information-processing circuits. Recently developed technologies can record brain activity from outside the skull. One technique is functional magnetic resonance imaging (fMRI)‚ which reconstructs a 3-D map of the subject’s brain activity. The results of brain imaging and other research methods show that groups of neurons function in specialized circuits dedicated to different tasks. The ability of cells to respond to the environment has evolved

    carrier impulses from the CNS to the periphery‚ the peripheral nerves in turn have the funsion to carry messages from one part of the organism to another‚ so we can understand the action of these drugs. They act in the prevention‚ generation and propagation of the nervous impulse. Acting on the blocking of the depolarization initiation‚ allowing Na + to enter the nerve cell from rest to the trigger threshold (- 50a - 60 mV) would consequently impede the initiation and propagation of the impulse. Therefore
