Neuroscience and Biobehavioral Reviews
|December 26, 2006
Summary
Nitric oxide (NO) is vital for memory consolidation, acting through more than just guanylate cyclase (GC). This review explores four additional NO-regulated targets involved in memory, including the ryanodine receptor (RyR) channel.
Area of Science:
- Neuroscience
- Molecular Biology
Background:
- Nitric oxide (NO) is crucial for memory consolidation.
- Current research predominantly focuses on NO's action via guanylate cyclase (GC) up-regulation.
Purpose of the Study:
- To review evidence for GC-independent mechanisms of NO action in memory processing.
- To highlight four key molecules regulated by NO implicated in memory.
Main Methods:
- Literature review of NO signaling pathways.
- Analysis of studies investigating NO interactions with enzymes, ion channels, and receptors.
Main Results:
- NO interacts with a wide range of cellular targets beyond GC.
- Four molecules—cyclic nucleotide-gated channels, calcium-activated potassium channels, ryanodine receptor (RyR) channels, and mono(ADP-ribosyl) transferase—are up-regulated by NO and linked to memory.
- Existing behavioral data suggest a connection between NO and RyR channels.
Conclusions:
- A singular focus on GC overlooks critical NO functions in memory.
- Investigating NO's role in RyR channels and other identified targets offers new avenues for understanding memory consolidation.

01:28Nitric Oxide Signaling Pathway
Nitric oxide (NO), an inorganic gas, acts as a potent second messenger in most animal and plant tissues. NO diffuses out of the cells that produce it and enters the neighboring cells to generate a downstream response. NO synthase (NOS) catalyzes NO production by the deamination of the amino acid arginine. There are three isoforms of NOS. Endothelial cells have endothelial NOS (eNOS), nerve and muscle cells have neuronal NOS (nNOS), and macrophages produce inducible NOS (iNOS) upon exposure to...
01:23Role 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.

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...
01:03Long-term Depression
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.
