Organization of the Brain01:30

Organization of the Brain

The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...
Brain Imaging01:14

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).
Regulation of Expression Occurs at Multiple Steps02:24

Regulation of Expression Occurs at Multiple Steps

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...

Area of Science:

  • Neuroscience
  • Genomics
  • Computational Biology

Background:

  • The mammalian brain functions as a multi-scale hierarchical system with connections and functions across micro to macro levels.
  • Genomic-scale expression profiling offers insights into brain architecture.

Purpose of the Study:

  • To present a novel methodology for correlating gene expression profiles with neuroanatomy.
  • To introduce a computational tool, NeuroBlast, for identifying co-expressed gene networks within and across neuroanatomic structures.

Main Methods:

  • Correlation analysis of gene expression profiles across tissue samples.
  • Development of the NeuroBlast tool for network identification.
  • Application to data modalities with sufficient spatial resolution.

Main Results:

  • NeuroBlast successfully identifies networks of genes co-expressed within or across neuroanatomic structures.
  • The methodology provides a computational technique to elucidate neuroanatomy using gene expression patterns.
  • A complementary technique identifies gene classes defining specific anatomic patterns.

Conclusions:

  • The presented methodology and NeuroBlast tool offer a powerful approach to understanding the relationship between gene expression and neuroanatomy.
  • This approach can be applied across spatial and temporal scales to map brain architecture.
  • It facilitates the discovery of gene classes crucial for defining anatomical structures.
