    Heart Rate Vulnerability

    • 1265 Words
    • 6 Pages

    Conclusion Heart rate variability has considerable potential to assess the fluctuations in the autonomic nervous system. Here we have examined the impact of meditation – Dialogue with the Body – on heart rate variability. A relaxing effect of meditation on Heart rate variability was observed. Thus this non-invasive methodology is of substantial utility to evaluate autonomic control mechanisms in spite of an incomplete understanding of the physiological significance of HRV parameters.

    Nernst Equation Lab Report

    • 1740 Words
    • 7 Pages

    The purpose of this experiment is to investigate the ionic basis of the neuron’s resting membrane potential (Vm). We examine how this potential is affected by potassium ion [K+] concentration and permeability using Orconectes rusticus crayfish abdominal muscles, and we ask whether or not the Nernst Equation solely based on [K+] can also predict the cell’s resting membrane potential. We predicted that [K+] concentration had a significant influence on the membrane potential and thus the Nernst…

    Kinesin Synthesis

    • 1650 Words
    • 7 Pages

    Our logic for choosing kinesin for developing CNS therapeutics is based upon our own research, which found that kinesins are transcriptionally upregulated during memory storage and that they are both necessary and sufficient to induce long-term memory storage (LTM) in the marine snail, Aplysia californica (Puthanveettil et al., 2008; Fig 1). Furthermore, other researchers have also discovered that an increase in specific kinesin function in the mouse forebrain improves working memory (Wong et al…

    Overview of The Myocyte The myocyte is composed of various protein filaments that comprise the contractile apparatus of the cardiac cell. Myofibrils, a collection of individual sarcomeres, enable contraction and relaxation of the myocyte. The sarcomere is the chief contractile unit of the cell. It is made up of two main proteins, myosin (thick filament) and actin (thin filament), as well as two regulatory proteins, tropomyosin and troponin. In order for the myocyte to contract and shorten it…
