What is Synaptic capacity?
Synaptic capacity refers to the maximum number of synaptic connections that can be formed between neurons in the brain. It is a measure of the brain's ability to adapt, learn, and store information. Increases in synaptic capacity are associated with learning and memory formation.
The spreading of neural pathways is a result of?
The spreading of neural pathways is a result of synaptic plasticity, which is the ability of synapses to strengthen or weaken over time in response to increased or decreased activity. This process allows for learning and memory formation by modifying the strength of connections between neurons.
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.
How does synaptic pruning in adolescence impact brain development and cognitive function?
Synaptic pruning in adolescence is a process where unnecessary connections between neurons are eliminated, allowing the brain to become more efficient. This process helps strengthen important connections and improve cognitive function by enhancing the brain's ability to process information and adapt to new experiences.
What is the theory of overproduction?
Overproduction is the ability of a species to produce far more offspring than can possibly survive. This leads to a 'struggle for survival'. Individuals with the most useful features (the best adaptations) also known as "survival of the fittest" will survive and leave more offspring than other individuals. Their offspring will inherit the useful variations and pass them on in their turn. This is the process of natural selection.
What is the mechanism of AchE inhibitor side effects of weakness?
When an acetylcholinesterase (AChE) inhibitor binds with acetylcholinesterase, regardless of whether it is reversible or irreversible, it prevents the ability of AChE to bind with acetylcholine (ACh) and break it down. Therefore, ACh accumulates in the synaptic gap, causing the postsynaptic neuron or muscle cell to fire/contract repeatedly. As this happens, a fatigue effect is reached due to depletion of chemical energy stores (ATP, etc.), and weakness results from the reduced ability of neurons/muscles to respond to further stimulation.
How many St. Jude hospitals are there in the US?
There is a St Judes Childrens Research hospital in Memphis, TN, which is widely supported for their cancer treatment of ALL children, regardless of ability to pay. In addition, there is a St Judes Medical System in California.
Demonstrate irritability and conductivity?
Irritability in physiology refers to a cell's ability to respond to a stimulus by changing its membrane potential, leading to an action potential. Conductivity refers to the ability of a cell to transmit this action potential along its membrane and to neighboring cells through gap junctions or synapses. Together, these processes allow for communication and coordination within the body's systems.
Do neurons demonstrate irritability and conductivity and transmit electrical messages from one part of the body to another?
Yes, neurons demonstrate irritability as they respond to stimuli by generating electrical impulses. They also have the ability to conduct these impulses along their length, allowing them to transmit electrical messages from one part of the body to another through synapses with other neurons.
How do nerve cells grow?
Nerve cells grow through a process called neurogenesis, where they divide and differentiate from precursor cells. This process is regulated by various growth factors and signals in the body's environment. Nerve cells also have the unique ability to form connections with other nerve cells, called synapses, allowing them to communicate and transmit information in the nervous system.
What is neural mechanism in memory?
Memory is regulated by interconnected regions of the brain, including the hippocampus and prefrontal cortex. Neurons within these regions form complex networks that encode, store, and retrieve memories through synaptic connections and long-term potentiation. The process involves the strengthening or weakening of neural connections, ultimately shaping our ability to remember past experiences.
The capacity of one brain area to take over the functions of another damaged brain area is known as brain?
Neuroplasticity or brain plasticity refers to the way that changes in neural pathways and synapses allow one part of the brain to "take over" damaged areas of the brain. It also refers to the brain's general ability to change as we age for both better and worse.
