Cerebral Hemispheres

Cerebral Hemispheres

The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

Gut-Brain Axis

Gut-Brain Axis

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...

Neurons as Communicators of the Brain

Neurons as Communicators of the Brain

Neurons, the fundamental units of the brain and nervous system, function as the primary transmitters of information throughout the body. Their ability to communicate through electrical and chemical signals is vital for every bodily function, from regulating the heartbeat to processing complex thoughts. Each neuron has three main components: the cell body (soma), dendrites, and an axon, each specialized to facilitate swift and efficient neural communication.

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).

Reason and Intuition

Reason and Intuition

The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the brain can only use...

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...

Area of Science:

Neuroscience
Cognitive Science
Computational Neuroscience

Background:

William James' dictum on the "sense of sameness" in thinking was initially misinterpreted.
The distinction between auto-correlation and cross-correlation in neural processing is crucial for understanding cognition.

Purpose of the Study:

To re-evaluate William James' dictum in the context of neural processing.
To experimentally determine if the brain utilizes auto-correlation or cross-correlation.
To propose a revised model of the visual cortex function.

Main Methods:

Analysis of William James' original dictum.
Design and execution of experiments to differentiate between auto- and cross-correlation in the brain.
Development of a new theoretical model for visual cortex function.

Main Results:

Preliminary experiments indicate the brain performs both auto-correlation and cross-correlation.
A revised view of the visual cortex as both an autocorrelator and cross-correlator is proposed.
The columnar structure of the visual cortex is assigned a significant role in this new model.

Conclusions:

The brain's computational mechanisms for thinking involve both auto- and cross-correlation.
A new perspective on the function of complex cells in the visual cortex is presented.
The proposed model offers insights into how neural circuits achieve thought, requiring further validation.
