  3. N E U R O P H Y S I O L O G Y ? Neurophysiology is a science of medical specialty that studies the central and peripheral nervous systems through the recording of bioelectrical activity, whether spontaneous or stimulated. ? These bioelectrical signals are gathered with differential amplifier studied. help of be to Introduction to Neurophysiology Procedures by Dr Chaman Lal PT 10/27/2018

  5. BIOLOGICAL SIGNALS ? PART I : What makes nerve cells excitable? ? Spontaneous electrical activity-EEG ? Establishment of the membrane potential ? Ion channels ? Generation of action potential and saltatory conduction ? PART II: How do nerve cells communicate with each other? ? Synaptic transmission (central versus peripheral) ? Neuromuscular junction ? PART III: Result of synaptic Transmission ? Clinical relevance Introduction to Neurophysiology Procedures by Dr Chaman Lal PT 10/27/2018

  6. Electroencephalogram EEG Electroencephalogram is the record of the spontaneous Excitatory & Inhibitory Postsynaptic potentials on Electroencephalograph (paper) by using Electroencephalography Technique. Introduction to Neurophysiology Procedures by Dr Chaman Lal PT 10/27/2018

  8. ELECTROMYOGRAPHY & NERVE CONDUCTION STUDY ? Electromyography is the study of motor unit action potentials via disposable needle electrodes to check either spontaneous activity or after active muscle activation /stimulation. ? Nerve conduction study is the study of the Action Nerve conduction study is the study of the Action Potential recorded from distribution) or Muscle belly after giving appropriate stimulation. skin (Cutaneous-Sensory ? Both test parts are studied together for final conclusion or diagnosis of the neuromuscular disease process. Introduction to Neurophysiology Procedures by Dr Chaman Lal PT 10/27/2018

  10. Membrane Potential Refers to the potential difference across the neuronal cell membrane ? Resting potential is usually between -60 to -70mV with net negative inside the membrane ? Membrane potential results from the separation of charge across the cell membrane ? Results from the unequal distribution of intracellular and extracellular ions ?
