Excitatory postsynaptic potential

Estimating the speed of neural transmission from hand-ankle (treatment A) and hand-hand (treatment B) Introduction A neuron is a specialised cell transmitting nerve impulses and its function is to transmit information within the nervous system which is a network of nerve cells and fibres which transmit nerve impulses between parts of the body. Neural transmission occurs when a neuron is activated (sends out an electrical impulse). Activation of a neuron takes place when the neuron is stimulated…

The brain works in mysterious ways. According to Dr. Rita Smilkstein we learn in a series of steps and something as to how you feel when learning something new depends on if you can even remember that knowledge. I believe that the way Dr. Smilkstein explains how the brain works is true compared to some of my own personal stories. According to the research of Dr. Rita Smilkstein, humans learn in five or six stages, which she calls the Natural Human Learning Process (NHLP). This was true of how I…

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…
