Summary
This study found that a combination of Gingko biloba (GB) and Codonopsis pilosula (CP) improved memory acquisition and retention more than GB alone or placebo. Both supplements also enhanced overall health status in participants.
Area of Science:
- Neuroscience
- Pharmacology
- Traditional Chinese Medicine
Background:
- Exploration of common Chinese herbs for cognitive enhancement is needed.
- Gingko biloba (GB) and Codonopsis pilosula (CP) are frequently used herbs.
Purpose of the Study:
- To evaluate the efficacy of GB alone and in combination with CP for memory acquisition and retention in healthy adults.
- To assess the impact of these herbal supplements on overall health status.
Main Methods:
- A double-blind, randomized, placebo-controlled trial was conducted.
- Sixty participants (aged 21-60) received either GB alone, a combination of CP and GB, or a placebo.
- Cognitive function was assessed using a standardized computerized test; overall health was measured by SF-12 and Medical Symptom Questionnaire.
Main Results:
- Both GB alone and the CP/GB combination significantly improved memory acquisition and retention compared to placebo.
- The combination of CP and GB demonstrated superior cognitive enhancement compared to GB alone.
- Participants taking the herbal supplements reported better overall health status.
Conclusions:
- The combination of Codonopsis pilosula and Gingko biloba appears more effective than Gingko biloba alone for improving cognitive function.
- Both herbal interventions positively impacted overall health status in the study population.

Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

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.

01:26Higher Mental Functions of Brain: Learning and Memory
1.9K
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

01:23Role of Neurotransmitters in Memory
2.4K
Neurotransmitters are integral to the brain's communication system, enabling neurons to transmit signals across synapses. This chemical exchange underpins various cognitive functions, including memory processes. The role of neurotransmitters in memory is multifaceted, influencing the encoding, consolidation, and retrieval of memories through their action on different neural circuits.

The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the...
