Event-related potential

unless acted upon by an outside force,” this is applicable to when the gymnast is running toward the vault, as well as, when the gymnast is in the air. Gymnasts use their own force to propel themselves around the bar when performing the uneven bars event and will remain in motion unless acted upon by an outside force, and, in this case, the outside force would be gravity pulling the gymnast downward. Newton’s second law of motion states, “Mass and acceleration are directly proportional in…

spatial summation (Maler and Rogers 1981). It will not fire upon input from only one T unit, it must receive synchronous input from various T units converging at the spherical cell at the same time (Maler and Rogers 1981). When this occurs, an action potential is generated. This was determined by a clever experiment in which, a fish was administer just enough anesthesia to disable its EOD (Maler and Rogers 1981). The researchers replaced its EOD with one that they produced and were able to…

Name: Institution: Course: Instructor: Date of Submission: Pendulum and spring Abstract In this lab, two systems namely a pendulum and a spring that exhibit simple harmonic motion were studied. The systems were subjected to a mass of known weight and allowed to oscillate. Afterwards, the period of each was determined. In addition, the harmonic properties in the systems and their limiting factors were determined through quantitative calculations. Introduction Any system that exhibits back and…

parts, which makes up the limbic system. An important part of the brain in the limbic system is called the hippocampus. It is a large part that is embedded in the temporal lobe on both hemispheres. The hippocampus is vital for making new memories of events and information. Another part of the limbic system is the hypothalamus. It is located below the thalamus. Disregarding its small size, the hypothalamus contains more than 40 neural pathways. The hypothalamus is responsible for increasing and…

Figure 1. An EMG Tracing of Triceps and Biceps Muscles Co-activation. EMG signal produces an electrical activity of the muscle fibers active at a moment time. The electrical activity is measured in millivolts per milliseconds. The top channel shows the bicep EMG, while the bottom EMG correlates to the triceps contraction traces. Shown on the top graph, there are two periods of bicep activation, each last approximately 1.5ms. When the biceps are activated, it produces increasing amplitude peaks,…

violently making it difficult to determine when the car reached each location. As the car went through the track, going up into the loops it grew in height, decreasing in kinetic energy while increasing in potential energy. This caused a greater energy loss due to the significant amount of potential energy transferred into kinetic energy. For example, the inverted curve follows after the lowest point in the roller coaster, which increases the height. This acts…

resistance is common. Stability is evident when adding toxins for selective pressure ensures that only the stable ones can proliferate in further cultivations10. In this experiment, we use the Geneticin (G418) toxin agent for isolating drugs with potential antagonism. G418 inhibits polypeptide synthesis (400 μg/mL is recommended). G418 resistance involves the addition of a Tn5 gene that encodes for an…

What does the term neroglia mean? What are the 4 types of neuroglia cells in the CNS? Discuss this in detail. Neuroglia is a group of cells, in the nervous tissue that supports neurons that keeps the nervous system functioning and together. The 4 types of neuroglis cells of the CNS: (1.) Astrocytes are cells that support and structure cells that is a barrier for the brain through blood. (2.) Microglial cells are cells that remove dirt and attack microbes. (3.) Ependymal cells are cells that…

Explanation of EMG signals EMG stands for electromyography. Muscle fibres generate tiny electrical currents prior to the production of muscle force. These currents are generated by the exchange of ions across muscle fibres membranes, a part of the signalling process for the muscle fibres to contract. EMG is the signal made, it can be measured by applying conductive elements or electrodes to the skin surface, or invasively with the muscle. When using EMG, tiny devices named electrodes are used…

Sensation and perception work together to help the brain make sense of the world we see. There cells, called sensory receptors, are the ones that send stimulus to the brain through afferent nerves, which are responsible for carrying information to the brain and spinal cord. This process is called the bottom-up processing, and it means that the information is being sent to the brain for interpretation. Then there is top-down processing, which works opposite of bottom-up processing. To make sense…
