WebApr 12, 2024 · The other major form of neurostimulation studied in both unipolar and bipolar depression is transcranial direct current stimulation, an easily implemented method of delivering a low amplitude electrical current to the prefrontal area of the brain that could lead to local changes in neuronal excitability.137 Like repetitive transcranial magnetic ... WebThe axon carries the electrical signals along the nerve cell to the axon terminal. An axon terminal. This is where the electrical message is changed to a chemical signal using neurotransmitters to communicate with the next group of nerve cells, muscle cells or organs. Neurotransmitters are located in a part of the neuron called the axon terminal.
