INTRODUCTION
Brain mapping has evolved as an experimental discipline that combines concepts from neuroscience, neuroimaging, psychology, psychiatry, technology, engineering, and artificial intelligence [1-7]. By transforming biological signals into clear data, neurotechnologies have advanced the understanding of the human brain, offering unprecedented insights into its anatomy and function, ultimately improving medical practice [8-11]. As research increasingly focuses on functional brain organization, specialists in neurology and related fields benefit from a better understanding of these fundamental concepts.
Neurotechnology is essential to for identifying and understanding neural organization and functioning, related to the ability to observe brain function in real-time can aid in diagnosing and treating various neurological diseases [11-12], and lay the groundwork for innovative applications, including brain mapping, thus revolutionizing our understanding of the brain and brain health [10-13]. Below are some of the most proeminent brain mapping technology for neuroscience research [13-15].
With notable advancements over the years, electroencephalography (EEG) and quantitative electroencephalography (QEEG) both analyze electrical patterns in the brain, providing information on its functions. EEG works by registering brain waves and evaluating their patterns, while QEEG uses complex algorithms to transform them into numerical data, which can improve understanding of neural networks and functional connectivity. Although these techniques are most commonly used for evaluating epilepsy, they can also be applied to stroke, traumatic brain injury, and neuropsychiatric disorders [12-14,16].
Furthermore, eye tracking (ET) is an emerging technology that offers biological, cognitive, and behavioral insights into brain processes by quantifying and analyzing eye movements. Over the years, it has been increasingly used in medical research and beyond, with applications in psychology, rehabilitation, and other non-medical domains. By evaluating gaze patterns, saccades, and fixations, ET offers valuable information on perception and information processing [11].
Notably, non-invasive brain stimulation techniques, such as repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS), are often used as supportive therapies in treating neurological and psychiatric disorders, particularly in patients who do not respond well to conventional treatments. In recent decades, research has shown their expanding applications in treating various disorders, such as major depressive disorder, chronic pain, and stroke, as well as for cognitive enhancement [17-19].
Finally, functional magnetic resonance imaging (fMRI) [6,9] and functional near infra-red spectroscopy (fNIRS) [6,8] are pivotal non-invasive technologies for brain mapping, assisting researchers to identify active brain regions during specific tasks by detecting changes in blood oxygenation levels. Magnetoencephalography (MEG) measures small magnetic fields generated by neuronal activity and is ideal for studying rapid neurological processes [20], which require timely resolution.
As society shifts from a single-disciplinary approach to a multidisciplinary model, neuroscience showcases the importance of converging perspectives. Understanding the complexities of the most advanced network – the human brain – is not a one-dimensional process; it requires expertise on multiple levels [21]. Whether applied in education, research, or clinical practice, this model can lead to innovation and benefit the world at large [21-22].
