MRI, or Magnetic Resonance Imaging, is used primarily for structural imaging of the brain, allowing us to see its anatomy in detail. Conversely, fMRI, or functional MRI, measures brain activity by detecting changes in blood flow, making it useful for studying brain function. While MRI provides excellent images of brain structure, fMRI has a much higher temporal resolution, capturing brain activity over time.
Explain the role of neurotransmitters in neuronal communication.
How to Answer
- 1
Start by defining neurotransmitters and their function in the nervous system.
- 2
Mention how neurotransmitters are released from presynaptic neurons.

Example Answers
Neurotransmitters are chemical messengers that enable communication between neurons. They are released from the presynaptic neuron into the synaptic cleft and bind to receptors on the postsynaptic neuron, which can initiate a response such as an action potential. Different neurotransmitters like dopamine or serotonin have specific roles, influencing mood, reward, and other functions. After their action, they are either reabsorbed or broken down, which regulates their levels.
