Chemical potential

in a neuron’s case it’s covered by a myelin sheath. The dendrites are the branches and the axon terminals bulbs are the tree stems. The same way all the parts play in how the tree works are the same in which all the parts of a neuron work. Electro-chemical impulses are like the tree trying to get nutrition to the roots, which is called synaptic firing in a neurons…

known as an Action Potentials (AP), which propagate down an axon to transmit a signal to another cell. The signal may be transmitted to another neuron through a synapse of another dendrite or will form a Neuromuscular junction with a skeletal muscle cell. Skeletal muscle consists of many multinucleated muscle fibers connected to intercalation of sarcoplasmic…

damage to the body. The effects of multiple sclerosis are seen as the result of occurrences taking place at a more molecular level. “If an axon loses myelin, it still lacks sodium channel in the areas previously covered with myelin, and most action potentials die out between one node and the next” (Kalat, p.44-45). Multiple sclerosis will present itself with a wide array of…

before it settles down. The wheel moves because you bouncing up and down as the scale gets rid of excess energy. You bouncing up and down because you have excess energy that is shifting back and forth between gravitational potential energy, kinetic energy, and elastic potential energy. This bouncing continues until sliding friction in the scale has converted it all into thermal energy. Only then the bouncing stop and the scale read your correct…

The neuron is the basic working unit of the nervous system. It is a specialized cell that is designed to transmit information to other cells across the body. Neurons make up such a large part of the brain, that they are also responsible for learning, reasoning, memory, and perception. The neuron comes from the portion of the body known as the nervous system, which is responsible for the impulses sent throughout the body. The neuron is composed of several parts in its structure and to ensure…

play. More specially the principle of energy. To make a catapult that could send a skittle through the air and into a bowl to reach its goal an energy had to be used, that energy was elastic energy. So what is elastic energy. Elastic energy is a potential mechanical energy…

Research Statement Past research accomplishments. Probing the dynamics of neuronal activities is crucial to understand the complex mechanisms of the brain and related diseases. Thus, there are great demands on optogenetic indicators for neuronal activities. However, engineering desired optogenetic indicators is a well-known challenge, probably due to the delicate sensing mechanisms, and the lack of effective high-throughput screen. To tackle this, I developed several novel molecular evolution…

According to the National Institute of Neurological Disorders and Stroke, there are more than 600 neurologic disorders 1. Neurodegeneration is one of the main contributors to Alzheimer’s, Parkinson’s, and Multiple Sclerosis. Neurodegeneration is the debilitating condition along with those diseases, which results in the healthy, functioning nerve cells to deteriorate and slowly die off. Deterioration gradually leads to the loss of cognitive skills, motor skills, and eventually death of the nerve…

How are humans, or any sentient life for that matter, anything more than complex arrangements of meat, neurons, and bone? The biophysical explanation of human physiology explains, quite in depth, the entire genetic makeup and biochemical arrangements from the simplicity of a ball and socket joint to the complexity of the brain. Surely the vast amount of research regarding human physiology could spearhead further research into the complexities of perception and thought, correct? There is no way…

zero scalar potential, the result of the calculation is to give a distribution function that is not a solution of the Vlasov equation as it is not a function of the constants of motion only. In essence, an additional exp(−r2) factor is required in the DF to counter exp(r2) terms that manifest by completing the square in the integration. The physical cause here would appear to be the inertial forces associated with the rotational bulk flow. If one assumes a non-zero scalar potential, then it…
