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...

Background:

The brain's complexity and limitations of in vivo studies hinder understanding.
Existing in vitro 3D tissue cultures are not yet functional for brain tissue.

Purpose of the Study:

To construct complex, functional, 3D brain-like cortical tissue in vitro.
To establish a model for studying brain homeostasis and injury responses.

Main Methods:

Formation of 3D compartmentalized architectures using primary cortical neurons.
Long-term in vitro maintenance of the engineered brain-like tissue.
Electrophysiological and biochemical assessments of tissue function and response to injury.

Main Results:

Successfully constructed functional 3D brain-like cortical tissue maintained for months.
Engineered tissue demonstrated electrophysiological function.
In vitro injury induced biochemical and electrophysiological responses mimicking in vivo observations.

Conclusions:

Developed a novel modular 3D brain-like tissue model.
This model enables real-time, non-destructive assessments of brain tissue.
Offers new avenues for investigating brain homeostasis and injury mechanisms.
