Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Magnetic Resonance Imaging

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Area of Science:

Neuroscience
Social Psychology
Cognitive Science

Background:

Close relationships are fundamental to human well-being.
Social attachment systems are linked to pain processing mechanisms.
Understanding how relationship closeness influences empathy is crucial.

Purpose of the Study:

To investigate neural differences when imagining pain from self, loved-one, and stranger perspectives.
To explore the impact of relationship intimacy on empathy-related brain activity.
To examine effective connectivity within pain processing networks based on perspective.

Main Methods:

Functional magnetic resonance imaging (fMRI) study.
Participants viewed animated stimuli of hands/feet in painful/non-painful situations.
Imagined scenarios from self, loved-one, and stranger perspectives after photo priming.

Main Results:

All perspectives activated the neural network for pain processing.
Loved-one perspective increased activity in anterior cingulate cortex and insula.
Stranger perspective increased activity in right temporo-parietal junction (TPJ) and superior frontal gyrus.
Greater relationship closeness correlated with reduced right TPJ activity.
Stranger perspective showed negative connectivity between right TPJ and insula.

Conclusions:

Intimacy significantly modulates bottom-up empathy processing.
Neural representations of self and others show greater overlap with increasing closeness.
Distinct neural pathways are engaged when empathizing with loved ones versus strangers.
