Which one of the following neurotransmitters or neuromodulators is NOT released by sympathetic preganglionic neurons?

Dendritic Nanotubes (DNTs) in the brain are primarily understood as structures that:

The typical resting membrane potential of a neuron is approximately:

Some features of Transcranial Direct Current Stimulation (tDCS) are stated below: A. The membrane potential of neurons is modulated by applying a weak electrical current between two electrodes placed on the scalp. B. Neurons under the anode become depolarized, and neurons under the cathode become hyperpolarized during tDCS. C. tDCS can disrupt neuronal activity and create a 'virtual lesion' via anodal stimulation. D. Neuronal activity is decreased in regions below the anode and increased in regions below the cathode. Which one of the following options represents the combination of all correct statements?
