Concept explainers
(a)
To determine: The diagram of a wave having a lower frequency.
Introduction: When an individual is sleeping, then more oxygen is consumed by the brain than when an individual is awake. Hence, sleep is a
(b)
To determine: The diagram of a wave having a larger amplitude.
Introduction: An electroencephalogram in open eyes state shows fast and irregular pattern without any dominant waves. In closed eyes state or sleep or coma state, neuron’s electrical activity initiates to synchronize into waves with characteristic patterns.
(c)
To determine: The diagram of a wave having a higher frequency.
Introduction: Most dreams in an individual take place during the period of REM sleep. The eyes seem to follow the action of the dream, so move behind the closed lids. During periods of REM sleep, there are more chances of sleepers to wake up spontaneously.

- When performing respiratory impedance plethysmography, two coils of insulated wire are sewn into elastic cloth bands in a sinusoidal manner. Over what are(s) of the body are the sinusoidal bands placed?arrow_forwardA) The following structure in the figure is a receptor for sensory information: A, B, C, D, E, F, G, H, I, J, K, L, M, N, O B)The following structure in the figure is an interneurone: A, B, C, D, E, F, G, H, I, J, K, L, M, N, O C)The following structure in the figure will carry information to skeletal muscle: A, B, C, D, E, F, G, H, I, J, K, L, M, N, Oarrow_forwardMatch following structures with their functionsarrow_forward
- How do phase shifts occur?arrow_forwardWhich one of these is an example of an excitatory postynaptic potential in a typical neuron? a) A voltage change from -70mV to -70.5mV b) A voltage change from +35mV to 0MV c) A voltage change from 0mV to +0.35mV d) A voltage change from -69.5mV to -70mVarrow_forwardWhich of the following is true regarding the difference between graded and action potentials? a.) Action potential occur only when the surface of the neuron is myelinated, but graded potentials occur in both in both myelinated and non-myelinated neurons. b.) The magnitude of action potential depends on the magnitude of the stimulus, whereas graded potentials are all or none. c.) The magnitude of graded potential depends on the magnitude of the stimulus, whereas action potentials are all or none.arrow_forward
- all of the following phrases decribe the same phenomenon except for one: a. action potential b. eletrical impusle c. power stroke d. depolarizationarrow_forwardOur brain receives more action potentials when our eyes are exposed to light even though our photoreceptors release more neurotransmitter in the dark.
