When neurons die why are they not replaced?
ALZHERMERS SYNDROME in simple terms In these diseases, neurons- the brain cells responsible for receiving, processing, and transmitting information- die and are not replaced. The current scientific literature makes one thing plain. As yet, there is no unifying hypothesis for the causes of Alzheimer's disease, Parkinson's disease, or many rarer degenerative brain diseases that cause dementia
When you learn something new you grow new neurons. What would you say to disprove this statement?
No. You don't grow new neurons, you grow more connections.
What is the link between neuron pathways and learning?
our core learning is recorded in the set of neurons. sensory neurons send decoding messages to the motor neurons. in case the information generated by one set of neurons is insufficient to solve the problem, the inter neurons send furthar questions through the pathways to another set of neurons and carries back the information to the earlier set of neurons. un answered questions get recorded in a new set of neurons as new experience.
In adults where are stem cells that produce new neurons?
in the brain
In adults where the stem cells that produce new neurons?
in the brain
Do neurons get replaced in the human brain?
No, neurons in the human brain do not typically get replaced. Once neurons are damaged or lost, they are not usually regenerated or replaced by new neurons.

How do neurons divide and regenerate in the human brain?
Neurons in the human brain do not typically divide or regenerate like other cells in the body. Once neurons are damaged or lost, they are not easily replaced. However, there is ongoing research on ways to stimulate neurogenesis, the process of generating new neurons, in certain regions of the brain. Additionally, some studies suggest that under certain conditions, existing neural stem cells in the brain may be able to produce new neurons.
Where is memory data stored in your brain?
Memory data is stored in various regions of the brain, primarily in the hippocampus and prefrontal cortex. The hippocampus helps with the formation of new memories, while the prefrontal cortex assists in the retrieval and processing of memories. Additionally, memories are believed to be distributed across a network of interconnected neurons in the brain.
Neuroscientists have recently found a biological basis for observational learning in the functioning of in the cerebral cortex?
Observational learning involves the process of acquiring new behaviors by watching others. Studies have shown that mirror neurons in the cerebral cortex play a role in this type of learning by firing not only when an individual performs an action, but also when they observe someone else performing the same action. This suggests a biological basis for how we learn from others through observation.
Lost neurons cannot be replaced because mature neurons cannot?
divide like other cells in the body. However, neural stem cells in certain areas of the brain have the potential to generate new neurons through a process called neurogenesis. This process primarily occurs in the hippocampus and olfactory bulb.
Can undamaged neurons make new connection with damaged neurons?
yes
How long does it take for dead grass to grow back?
Dead grass does not grow back. It needs to be removed and replaced with new grass seeds or sod.
Can nerve cells divide and regenerate in the human body?
Nerve cells, or neurons, generally do not divide and regenerate in the human body. Once they are damaged or lost, they are not easily replaced. However, there are some regions in the brain where new neurons can be generated through a process called neurogenesis.
When you learn something new do you grow new neurons?
That is a complicated and very good question. In humans (mammals) neurons are formed during development throughout the cortex. At adulthood, this continues only in the hippocampus and olfactory bulb. Therefore the rest of the cortex is made of all the same neurons for the rest of your life (n.b. you can lose them). Therefore learning new things is probably the result of neuro-placticity rather than neurogenesis. However, There are two general types of memory; episodic and semantic. Episodic are the ones that you can imagine because you experienced them. As opposed to semantic- dry info you've studied. Episodic memories seem to be consolidated by the hippocampus which may play memories back during REM sleep. This may be the result of neurogenesis. However, the new cells that are formed will not be the loci of the memories they are the mechanism of storing the memories in the neocortex.
When you learn something new you grow new neurons. What would you say to disprove this statement?
No. You don't grow new neurons, you grow more connections.
Does dead mycardial tissue get replaced?
Dead myocardial tissue does not regenerate or get replaced by new healthy tissue. Instead, the body forms scar tissue in place of the dead tissue. This can lead to decreased cardiac function and potential complications.
