Role of Neurotransmitters in Memory

Role of Neurotransmitters in Memory

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.

Glutamate, the brain's main excitatory neurotransmitter, is...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

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.
