Parallel Processing

Parallel Processing

The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...

Visual System

Visual System

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

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 human brain's processing capabilities offer insights for developing advanced machine learning algorithms and architectures.
Understanding brain function is crucial for bridging the gap between biological intelligence and artificial systems.

Purpose of the Study:

Introduce Brain Activation Network (BRACTIVE), a transformer-based framework for studying the human visual brain.
Align visual features with brain representations using functional Magnetic Resonance Imaging (fMRI) to identify Regions of Interest (ROIs).
Enable multi-subject and multi-ROI identification, overcoming limitations of previous methods.

Main Methods:

Developed BRACTIVE, a novel transformer-based framework.
Utilized fMRI signals to map brain activity to visual features.
Implemented a method for automatic extension of ROI identification across multiple subjects.

Main Results:

BRACTIVE successfully identified person-specific ROIs, including face and body-selective areas, consistent with neuroscience findings.
Demonstrated potential applicability to diverse object categories.
Showcased that integrating human visual brain activity into deep neural networks improves benchmark performance.

Conclusions:

BRACTIVE offers an effective approach for identifying subject-specific brain regions related to visual processing.
Leveraging human brain activity via BRACTIVE enhances deep neural network performance.
The framework holds significant potential for advancing both neuroscience and machine intelligence research.
