What are the three most common methods of measuring brain function?

How can we study the structure of brain?

  • The brain parts having greatest electrical activity can be linked with behaviors and sensations of the body. This will tell how the body surfaces are represented in the brain. The structural features of neurons and fiber connections can be studied through microscopic examination of brain tissues. This method is called as histology.

What tools do Neuroscientists use to study the brain?

  • As a result, neuroscientists have a suite of tools at their disposal. Some of these, such as fMRI and EEG, can be used in humans because they are non-invasive; they work through by looking into the skull. But these tools suffer from a lack of detail. To get a more microscopic picture of neuron activity, researchers turn to animal models.

How can we stimulate a specific part of the brain?

  • A specific part of the brain may be stimulated either by electric current or by chemicals. Through electrical stimulation, we can only stimulate the desired part of the brain. But by chemical methods, we can stimulate or defunct a particular part of the brain for a fixed period of time and observe their effects on behavior.
