What type of technique would allow you to visualize the nerve electrical signal of the brain? Is it possible to do that with MRI?
Here is a good review of current brain imaging techniques:fredreload said:Is there another imaging technique more detailed than mri in terms of showing nerve impulse?

An electrical signal in the brain refers to the transmission of information through a series of electrical impulses between neurons. These signals are responsible for all brain functions, including movement, sensation, and thought.
An electrical signal travels through the brain by passing from one neuron to the next through a junction called a synapse. When a neuron receives a signal, it releases neurotransmitters that cross the synapse and bind to receptors on the next neuron, triggering an electrical impulse in that neuron.
Electrical signals in the brain can be measured using techniques such as electroencephalography (EEG) or magnetoencephalography (MEG). These methods involve placing electrodes on the scalp to detect the electrical activity of the brain.
Synapses play a crucial role in the brain's communication system. They allow for the transmission of information between neurons, facilitating various brain functions. The strength and efficiency of synapses can also change, which is essential for learning and memory processes.
Yes, both electrical signals and synapses can be affected by mental health disorders. Imbalances in neurotransmitters, which are responsible for transmitting electrical signals, have been linked to conditions such as depression, anxiety, and schizophrenia. Changes in the structure and function of synapses have also been observed in individuals with various mental health disorders.
