The electroencephalogram (EEG) is a record of the oscillations of brain electric potentials. The EEG provides a convenient window on the mind, revealing synaptic action that strongly co-relate with brain state. Fractal dimension, the measure of signal complexity can be used to characterize the physiological conditions of the brain. As the EEG signal is non linear, non stationary and noisy, non ...

The response of excitable cells to inhibitory nerve impulses has already been studied with intracellular electrodes in several preparations. In the spinal cord of the cat an inhibitory volley sets up a transient polarization of the motoneuron, preventing it from discharging (Brock, Coombs, and Eccles (4)). In the crustacean nerve muscle junction inhibitory impulses have a dual effect. They atte...

Disturbances in the propagation of the heart beat between the auricle and the two ventricles are of frequent occurrence and well known under the terms A-V dissociation or heart block. The term sinoauricular block is the standard name for an apparent block between the sinus node and the auricle, a hypothetical incident to explain transient auricular standstill for a period of time that is a mult...

Background: Traumatic or iatrogenic full thickness auricular defects can be reconstructed in many ways. The defects exceeding 2 cm require challenging reconstruction techniques. The reconstruction options for those should include anterior and posterior skin envelope repair with cartilaginous content. Providing color and texture match, while maintaining anatomic landmarks, should be considered. ...
