Lafora disease is a rare, inevitably fatal, autosomal recessive, progressive myoclonus epilepsy. Being autosomal recessive, the disease is most commonly seen in communities that practice consanguinity. The onset of the disease occurs within the first two decades of life, with an average life span of 10 years following diagnosis (Monaghan & Delanty, 2010). Lafora disease is characterized by myoclonic and tonic-clonic seizures and neurological dysfunction, such as dementia (Monaghan & Delanty,…

My testable question is an off the ground spike more powerful and faster than a spike that is done on the ground. I will answer this by spiking the volleyball ten times, five times in the air and five times from the ground. I will be ten feet away from the wall and I am going to measure how high it bounces after it touches the ground. I chose this topic because I love volleyball and I wanted to know which position has more force and power. My hypothesis is “If an off the ground spike is made,…

The experiments showed that the rate of action potentials can be affected by different stimulus and obstacles, like temperature or rate of which the action potential reaches the source though different obstacles. The earthworm experiment showed that action potentials work best under normal temperatures at which the organism can operate under like room temperature. Like in the FM imaging experiment it showed that most the earthworms sensors are on the surface of the earthworm, if the temperature…

Last Thursday, I had a hockey practice, and before anyone else came on the ice, my brother Michael and I were just shooting around. To see how fast my slapshot is, I had him stand at the other end of the ice, and using his phone, see how long it took for my shot to go from one goal line to the other, exactly 60.96 meters. Keeping the puck on the ice the whole time during my shot, changing just the position of the puck, my slapshot took 4 seconds to cross the far goal line, making my slapshot…

The difference between excitatory and inhibitory neurotransmitters are excitatory neurotransmitters lead to changes that generate action potential in a responding neuron. Inhibitory neurotransmitters block the changes that cause action potential to be generated in the responding cell. The function of receptors are to bind a specific chemical substance. An example of this would be, "...a dopamine but does not bind other neurotransmitters…

Neuronal regeneration is a high energy demanding process however, with maturation, axonal mitochondria transport progressively declines. Mitochondria are cellular powerhouses that supply ATP; essential for neuron growth, survival, and regeneration. Motile mitochondria can become stationary and in mature axons of the central nervous system (CNS), the majority of the mitochondria become stationary with only about 20-30% remaining motile. With this reduction in mitochondrial transport, mature CNS…

excitable cells, as they have the ability to produce an electric current to formrom an action potential from using a concentration gradient of ions across their membrane (Sherwood, 2013). The current generated by the flow of sodium (〖Na〗^+) and potassium ( K^+)ions is called an action potential and occurs in three steps: depolarization, repolarization, and hyperpolarization. First, a membrane potential 〖(V〗_m) is established by creating a concentration gradient of 〖Na〗^+ and K^+where there is a…

dside America photograph archive (1972–2008), Library of Congress, Prints and Photographs Division. Once everyone's onboard, the cars are released and start to roll down. When they round the brow of the first hill, the force of gravity makes them hurtle energy as well. Even the rattling noise the rollercoaster makes uses up some of its energy. The cars lose more and more of their original energy the longer the ride continues, and, since the cars have no engines, there's no way of replacing it.…

Tidal energy is a renewable energy created by using gravitational forces from the sun and the moon. Since the moon rotates around the Earth, and the sun’s placement is constantly changing, the sea levels are always rising or falling. These different levels create the tide cycle and energy is gathered from the difference in sea levels, currents, and tides. Tidal energy can appear complex and confusing but this quote provides a brief explanation of how tidal energy is defined and gathered: “Tidal…

the firing of action potentials in neuronal cells in the brain. The research presented in the paper “High-Fidelity optical reporting of neuronal electrical activity with an ultrafast fluorescent voltage sensor” shows just how far brain mapping has come and how far it still has to go before all pathways are truly understood. This paper presents the medical community the opportunity to harness the versatility of Green Fluorescent Protein (GFP) in order to show how action potentials are initiated,…
