![]() The cell body (soma, bottom) is about 1/40 of a millimeter in size.The head contains all the components the neuron needs to receive information from other cells, including molecules on its surface called receptors, which can bind to substances called neurotransmitters that carry signals between neurons and substances that control the number of receptors and their activity. The head is the place where two neurons connect and exchange information, an area called the synapse. A dendritic spine looks like a mushroom ( Figure 1), with a large head and a thin neck. Let us begin by describing the parts of the dendritic spine. This article will explain, support, and expand on this hypothesis. Most of what we know supports the idea that these spines are one of the main places in the brain where memories are created and stored. Since then, we have learned a huge amount about dendritic spines. For this work, Ramon y Cajal won the Nobel Prize for Physiology or Medicine in 1906. He discovered that brain neurons have thousands of tiny outgrowths, each about 1/1,000 of a millimeter long, which are now called dendritic spines. At that time, the Spanish researcher Ramon y Cajal discovered that the membrane, or outer covering, of brain neurons was not as smooth as scientists previously thought it was. Future studies may help us answer this fascinating riddle.Ībout 130 years ago, powerful microscopes were developed that allowed researchers to see brain cells called neurons in more detail. However, there is still a long way to go before we can identify exactly where memories are kept in the brain. Likewise, preventing dendritic spines from changing may stop memories from forming. This hypothesis is based on hundreds of studies showing that forming a memory causes dendritic spines to undergo major changes in number, size, and shape. Since dendritic spines can change shape and size quickly, some researchers have suggested that they are the structures in the brain where memories are created and stored. Even with the latest technology, it is very difficult to research dendritic spines because they are so tiny-one dendritic spine is about 1/1,000 of a millimeter, and there are thousands of them on the surface of most nerve cells in the brain. Since then, scientists have been trying to understand what dendritic spines are and how they function in the brain. INCA Ingénieurs Conseils Associés, Niederanven (engineer) A.M.Over 100 years ago, Nobel Prize winner Ramon y Cajal first described structures called dendritic spines, located on the surface of brain cells. From outside of the Labyrinthe, visitors and passersby will be able to see the top of the tree-like form, reaching above the walls of the maze from all directions.įonds d’urbanisation et d’aménagement du plateau de Kirchberg, Luxembourg Each of its branches extends in a different direction, allowing for a panoramic view of the surrounding gardens, art works, and architecture. A thought in the brain travels through dendrites much like a human ascending the sculpture and both inevitably lead to the goal of processing the structures of our world. As one ascends the stairway, they encounter a point where they must choose one path that leads directly to an observation point, or select a second pathway that then also requires a further decision. The sculpture’s tree-like structure, requires visitors to choose a particular path to climb. Within the context of the Labyrinthe du Parc Central, Dendrite-a reference to the branched structure of the neurons that constitute our minds-provides visitors with the opportunity to climb above the encompassing walls of the maze, giving the chance to see the architecture of their pathway to the centre (as well as the vibrant surrounding landscape of the Plateau de Kirchberg), and, to preemptively observe their subsequent path to the exterior.
