The Reference Signal Model - Eye movements are often made over a stationary background, which means that the retinal image contains information about eye velocity. Reference signal models therefore combine extra-retinal, retinal and vestibular information to generate a single compound signal. Since retinal motion generating extra-retinal information is somewhat contradictory, the extra-retinal signal of the classical model is replaced by a reference signal (Wertheim, 1994). Figure 2.3 presents a schematic for a simple reference signal model, which does not include vestibular information....   [tags: Medical Science] 1731 words

Anatomy: How the Muscles Work - In order for a skeletal muscle to contract, a signal must be first sent from the primary motor cortex which is located in the precentral gyrus of the cerebral cortex. This is considered to be an Upper motor neuron. These fibers travel through the brain via the internal capsule until they get to the lower portion of the medulla oblongata. At this point, the neuron crosses over to the other side of the body. This means that if a neuron is to inervate the right bicep muscle, it originated in the left side of the precentral gyrus and crossed over to the right side at the medulla oblongata....   [tags: signals, neurons, membrane] 1613 words

Baher (2001, p. 2) states that the natural world we live in, as well as most artificial sources, produce signals which we have grown accustomed to consider mainly of the analog type. This means that the signal f (t) is defined, somehow, for all values of the continuous variable t, and its amplitude can assume any value of a continuous range.

Taking a Look at Audio Compression - ... Due to the transmission of signal along with the noises like background noise, environmental noise and the noise present in signal itself leads for the distortion and loss of information, such that the transmission is not much effective. In between the output transponder and microphone there is a positive feedback loop which affects the hearing aid. The stable gain achieved in the forward path and the sound quality at the output is reduced by this feedback [1]. Since the hearing aids are used to correct impaired hearing, it should be tuned from the lower range of frequency to the normal audible frequency....   [tags: multimedia applications] 921 words

Activation of Protein Kinases by Means of Stochastic Resonance - ... It often occurs in bi-stable systems or in systems with a sensory threshold and when the input signal to the system is "sub-threshold". As pointed out for lower noise intensities, the signal does not cause the device to cross threshold, so little signal is passed through it. For large noise intensities, the output is dominated by the noise, also leading to a low signal-to-noise ratio. For moderate intensities, the noise allows the signal to reach threshold, but the noise intensity is not so large as to swamp it....   [tags: cellular function]
