What are different types of cells that are post-synaptic?
Post-synaptic cells can vary widely depending on their location and function in the nervous system. Common types include neurons, which can receive signals from other neurons, and glial cells, such as astrocytes, which can modulate synaptic activity and support neuronal function. Additionally, muscle cells (myocytes) can serve as post-synaptic targets in neuromuscular junctions, responding to signals from motor neurons. Each type plays a distinct role in processing and responding to neurotransmitter signals.
What are few limitation to using multipotent stem cells?
Multiplicity of differentiation potential is limited, lower plasticity compared to pluripotent stem cells, and may not be able to differentiate into all cell types needed for therapy in certain cases.
What is behavioral plasticity?
Morphological plasticity is the tendency of a species to physically change appearance due selective breeding. Some species, like dogs, have a high degree of morphological plasticity - a few generations can turn a wolf into a chihuahua - whereas others, such as humans, have such a low degree that thousands of years of separation yields only minor changes to facial structure and hair type. The mechanisms which govern this effect are complex and numerous, but there seems to be a correlation between high plasticity and the species' natural rate of environmental adaptability.
What does it mean when a material has the property of plasticity?
Think of plasticity as the opposite of elasticity. Elastic materials will deform under an applied force, but will return to their original shape when the force is removed. It is also the opposite of "easy to crack." We are not speaking of gasses or liquids. Plasticity is a property of many solids which tend to keep their new shape once deformed by an applied force. Soft metals like copper and lead are highly 'plastic.' They are easy to hammer into a new shape or draw out into a wire. Rock candy, peanut brittle, and high-carbon steel tools made for cutting have a very low plasticity. They are brittle. Rubber bands also have a low plasticity, as they return to their original shape when let go. Ironically, many types of plastic (vernacular usage) are easy to shatter under stress, and so have very little plasticity, by definition.
The chemically gated channel known as NMDA allows what ions entry into the nerve cell?
The NMDA channel allows calcium and sodium ions to enter the nerve cell in response to glutamate binding. These ions play key roles in neuronal excitability and synaptic plasticity.
What does the synaptic plasticity do in learning?
It allows neuronal development in response to novel experiences.

What is the endocannabinoid systEMS?
neuromodulatory lipids and receptors involved in a variety of physiological processes including appetite, pain-sensation, mood, motor learning, synaptic plasticity, and memory.
What is the synaptic basis for learning and memory?
Learning and memory involve changes in synaptic strength and connectivity between neurons, known as synaptic plasticity. This may include long-term potentiation (LTP), which strengthens synapses, and long-term depression (LTD), which weakens synapses. These changes in synaptic transmission are thought to underlie the formation and storage of memories in the brain.
What are different types of cells that are post-synaptic?
Post-synaptic cells can vary widely depending on their location and function in the nervous system. Common types include neurons, which can receive signals from other neurons, and glial cells, such as astrocytes, which can modulate synaptic activity and support neuronal function.

You remember where your N methyl D aspartate or NMDA receptors are?
NMDA receptors are located in the brain, specifically on the surface of neurons. They play a crucial role in controlling synaptic plasticity and memory formation. Additionally, NMDA receptors are involved in regulating synaptic transmission and are important for learning and memory processes.
What do you mean by neurons that fire together wire together?
This phrase from Donald Hebb's theory of synaptic plasticity suggests that when two neurons are activated at the same time, the connection between them strengthens. This concept implies that repeated co-activation of neurons strengthens their synaptic connection, leading to more efficient communication in the brain.
What is most likely to imitate calcium's role in the function of neurons?
Magnesium is most likely to imitate calcium's role in the function of neurons. Magnesium can affect synaptic plasticity and neurotransmitter release, similar to calcium.
What is syboxin?
Syboxin is a novel investigational drug being developed for the treatment of various neurodegenerative diseases, particularly those associated with synaptic dysfunction. It acts as a selective modulator of specific signaling pathways, aiming to enhance synaptic plasticity and improve cognitive function. Research is ongoing to fully understand its efficacy and safety profile in clinical settings.
How does neurons in brains retains memories?
Neurons retain memories through a process called synaptic plasticity, where connections between neurons (synapses) are strengthened or weakened based on repeated patterns of activation. When memories are formed, these synaptic connections are modified, creating lasting changes in the brain's circuitry that store the memory. Memories are thought to be stored in various regions of the brain, with different types of memories being stored in different areas.
What are few limitation to using multipotent stem cells?
Multiplicity of differentiation potential is limited, lower plasticity compared to pluripotent stem cells, and may not be able to differentiate into all cell types needed for therapy in certain cases.
