Summary
A herbal nasal remedy, based on traditional Chinese medicine, was found to increase brain activity in the frontal lobe and anterior cingulate cortex (ACC). This suggests potential benefits for neurological disorders.
Area of Science:
- Neuroscience
- Pharmacology
- Traditional Chinese Medicine
Background:
- Traditional Chinese Medicine (TCM) principles, such as clearing orifices, are utilized in developing herbal remedies.
- The Shaolin monk-developed herbal remedy targets nasal cavity application.
Purpose of the Study:
- To investigate the neuro-electrophysiological effects of a specific herbal nasal remedy.
- To assess the impact of the herbal remedy on brain activity, particularly in the frontal lobe and anterior cingulate cortex (ACC).
Main Methods:
- A repeated-measures design involving 14 healthy adults.
- Intranasal administration of the herbal remedy and a saline control.
- Electroencephalography (EEG) recordings and LORETA analysis to examine brain activity and cerebral perfusion.
Main Results:
- The herbal remedy, unlike saline, significantly increased cordance, an indicator of cerebral perfusion, in the anterior brain region.
- LORETA analysis revealed increased activity in the anterior cingulate cortex (ACC) following herbal remedy application.
Conclusions:
- The herbal nasal drop demonstrated preliminary evidence of enhancing frontal lobe and ACC activity.
- These findings suggest potential clinical applications for the herbal remedy in treating frontal lobe disorders.

01:25Olfaction
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function. They...
01:24CNS Stimulants: Cocaine, Amphetamines and Cannabinoids
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its effects by...
01:28Adrenergic Agonists: Mixed-Action Agents
Mixed-action adrenergic agonists, like ephedrine and pseudoephedrine, directly and indirectly affect adrenergic receptors. These agents stimulate adrenoceptors and indirectly release stored neurotransmitters, amplifying the adrenergic response.
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
