Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists01:30

Cognitive 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...
Working Memory01:24

Working Memory

Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this information.
Role of Cerebellum and Prefrontal Cortex in Memory01:14

Role of Cerebellum and Prefrontal Cortex in Memory

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 cerebellum's...

Higher Mental Functions of Brain: Learning and Memory

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 playing an...
Neuroplasticity01:01

Neuroplasticity

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.
Brain Imaging01:14

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).

Area of Science:

  • Cognitive Neuroscience
  • Translational Medicine
  • Neuroscience

Background:

  • Working memory (WM) enhancement is a key goal in cognitive science.
  • Neural communication, specifically frontomedial theta and posterior gamma oscillations, is linked to WM performance.
  • Limited evidence exists on how training strategies and neuromodulation interact to boost WM.

Purpose of the Study:

  • To investigate how strategy-based working memory training and neuromodulation influence neural communication.
  • To explore the role of theta-gamma oscillation coupling in WM enhancement.
  • To determine if targeted neuromodulation can selectively improve cognitive-neural plasticity.

Main Methods:

  • Analysis of electroencephalography (EEG) data during strategy-based WM training with neuromodulation.
  • Observation of theta-gamma oscillation coupling changes associated with WM improvements.
  • Application of high-definition transcranial Direct Current Stimulation (HD-tDCS) to the left dorsolateral prefrontal cortex (LPFC).

Main Results:

  • WM enhancements correlated with altered theta-gamma oscillation coupling.
  • HD-tDCS applied to LPFC led to improved WM performance.
  • The intervention resulted in slower frontomedial theta oscillations, indicating enhanced WM.

Conclusions:

  • Cognitive-neural pattern plasticity can be rapidly and selectively enhanced through neuromodulation.
  • Leveraging spatial frequency coupling within specific cortical circuits is crucial for strategic memory improvement.
  • This research provides a framework for optimizing memory enhancement interventions.
