|April 2, 2015
Summary
Melaxene (3 mg) enhances human brain function by increasing neural synchronization across EEG rhythms. This neurophysiologic study shows Melaxene boosts left hemisphere activity and connectivity.
Area of Science:
- Neurophysiology
- Brain Function Analysis
Context:
- Investigating the impact of pharmacological agents on cognitive processes.
- Utilizing electroencephalography (EEG) for dynamic brain activity monitoring.
Purpose:
- To determine the effects of a single 3 mg dose of Melaxene on human brain functional state.
- To analyze changes in electroencephalography (EEG) rhythms and spatial synchronization patterns.
Summary:
- A 12-hour neurophysiologic study demonstrated that Melaxene reliably increases cross-correlation parameters of global spatial synchronization in EEG rhythms.
- Melaxene administration was shown to activate cross-correlation links in spatial synchronization between the left and right brain hemispheres.
- Functional asymmetry analysis indicated a dominant activation of the left hemisphere following Melaxene intake.
Impact:
- Provides insights into Melaxene's mechanism of action on brain connectivity.
- Suggests potential applications in modulating neural activity and hemispheric balance.
- Highlights the role of EEG in assessing drug-induced neurophysiological changes.

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...

Pigmentation
5.0K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

Biological Influences on Intelligence
704
Intelligence is often thought to be linked to brain size, but the relationship is more complex than that. While brain size does correlate modestly with some abilities, like verbal skills, the connection is weaker for others, such as spatial reasoning. Other factors, like brain structure, also play crucial roles. For instance, despite Einstein's smaller-than-average brain, his parietal cortex, which is involved in spatial reasoning, was 15% wider, suggesting that neural density might matter...

Changes in Skin Color: Clinical Perspectives
4.2K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

Functional Brain Systems: Limbic System
9.4K
The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

Human Genetics

Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
