On January 9, 2014 a new discovery was made, Penn State university molecular biologists discovered that dendrites are able to regenerate after deletion. In most neurons, in order for one to function properly you would need both the axons and dendrites. In animals there is always constant regeneration and degeneration. When you look deeper into the idea of regeneration and degeneration we notice that regeneration with peripheral neurons occur more often than central neurons. (Huebner & Strittmatter, 2009) Peripheral neurons come from the peripheral nervous system (PNS). (Jasvinder, 2013) They include all the neurons in the body minus the brain or spinal cord, and functions to supply sensation or motor messages to the skin and skeletal muscles (Jasvinder, 2013) Central neurons come from the central nervous system (CNS), and refers to the neurons that are related are in your spinal cord and your brain. (Chudler,2013) From scientific research we already know that axons are able to regenerate after being injured, through multiple complex phases but it is possible. But the purpose of this paper is to talk about the new discovery about Dendrite regeneration, because for many years that has been an unanswered question. For many years people suspected that it was possible to repair damaged dendrites, but were never truely able to test whether it was possible on mammals. (Gao and Chen, 2011,Greenwood and Connolly, 2007) Since it’s nearly impossible to test on mammals biologists decided to take a turn and test it on Drosophila. When people refer to Drosophila they are basically talking about fruit flies. So biologists decided to do labs on Drosophila dendrite arborisation neurons hoping to determine whether it is or is not possible for den...

  • Reversing Stroke and Spinal Cord Damage

    1718 Words  | 4 Pages

    Until recently there was virtually nothing doctors could do for the 500,000 Americans who have strokes each year, the 500,000 to 750,000 who experience severe head injury, or the 10,000 people who are paralyzed after spinal cord damage (3). However, that is about to change. Researchers now think it may be possible to replace destroyed brain cells with new ones to give victims of stroke and brain injury a chance to relearn how to control their body, form new thinking processes, and regain emotions. After demolishing the long-standing myth that brain cells cannot regenerate or proliferate, scientists are developing ways to stimulate cells to do just that. Although stroke, head injury, and paralysis are three of the most devastating things that can happen to anyone, scientists have recently learned that the damage they cause is not preordained. It takes place over minutes, hours, and days, giving them a precious opportunity to develop treatments to halt much of the damage. Most of the new remedies are not yet available, but an explosion of research in the last five to ten years has convinced scientists that some of them will work (8).

  • How Flexible is the Brain's Circuitry?

    In elementary biology, we are all taught that cells in our body go through systems that replaces old, worn out cells with new cells. Most cell types go through programmed cell death, or PCD, but there was always an exception in the neuron; very early in mammalian development, neurons stop growing (4). PCD would be disastrous, as the depleted neurons would never be replaced. Since we need all our neurons and their connections to function, how do individuals with damage to both these neurons and connections survive, much less functioning within any definition of normality? After all, remove a few chips from a computer's motherboard and you won't have functioning computer. Yet there are children living their lives with only half their brains intact

    The neurons or brain cells are shaped like trees. Young brain cells, called soma, resemble an acorn or small seed of a tree. The seed sprouts limbs when stimulated, called dendrites. Further on in development, the cell will grow a trunk like structure called an axon. The axon has an outer shell, like the bark of a tree, called the myelin sheath. Finally, at the base of the cell, there are root-like structures called axon terminal bulbs. Through these bulbs and the dendrite of another cell, cells communicate with each other through electrochemical impulses. These impulses cause the dendrites to

  • Pros And Cons Of Synaptic Pruning

    279 Words  | 1 Pages

    Synaptic pruning signifies the requisite process of the developing brain in which unnecessary neural interfaces within the brain are removed; it has been supported to improve energy conservation and monitor efficiency concerning the mind. Unsurprisingly, synaptic pruning tends to continue long after the brain has matured, and typically goes hand-in-hand with a process known as myelination: When remaining neurons are coated in a fatty-layer called myelin that accelerates synaptic charges and protects neural connections. "The classic 'use it or lose it' principle applies to adolescence—those circuits that are actively engaged may remain, those underutilized may be subject to systematic destruction." Based on the previous quote, the underlying

Various organizations such as the “International society for neurochemistry” and the “European Brain and behavior Society” exist today to further the study of the nervous system and expand human understanding of medical and psychological ailments. The actual study of the nervous system dates all the way back to ancient Egypt where surgeons would drill holes into the human skull in order to alleviate a variety of aliments. The second half of the 20th century furthered the study of neuroscience via advancements in Molecular biology, and electrophysiology. These advancements are currently being used to study potential solutions to diseases such as (ALS) amyotrophic lateral sclerosis, strokes, and brain trauma. This research is funded by credible organizations such as the (NIH) National Institute of Health and the “National S...

  • Understanding the Brain: Synaptic Pruning

    901 Words  | 2 Pages

    During early childhood, there is a huge proliferation of connections between neurons, usually peaking around the age of two. The adolescent brain then cuts down the amount of connections, deciding which ones are important to keep and which can be let go. While there are various theories as to the molecular mechanisms by which pruning actually occurs, most agree that pruning is primarily carried out by a very motile form of glial cell, called microglia [1], and pre-programmed cell death (apoptosis). These microglia are thought to remove cellular debris and perform surveillance during the healing process of an injured brain, but in the healthy, developing brain they have a possibly more important function. If a synapse receives little activity, it is weakened and eventually deleted by microglia and other glial cells through a process called long-term depotentiation (LTD). After the synapse has been removed, the space and resources that it once used are taken by other synapses. These synapses are strengthened by long-term potentiation (LTP). These processes and various others take place throughout development, peaking at adolescence and reaching their base around the age of 21, and transform the brain to create more complex and efficient neuronal configurations.
