The three different waveforms are a representation of the electrical activity of the heart. The P wave represents the depolarization of the atrial valve. The QRS complex represents the depolarization of the ventricular valve. Also‚ the T wave represents the repolarization of the ventricular valve. The change in amplitude represents the different heartbeat patterns such as normal‚ fast‚ slow

following step the cells and mitral axons form the lateral olfactory tract. Finally‚ this tract travels from the olfactory bulb to the limbic system. From the olfactory bulb‚ olfactory information is processed in the primary olfactory cortex‚ amygdala‚ septal nuclei‚ hippocampus‚ and the entorhinal cortex. An important factor which has to do with olfactory information is that it can be associated with the limbic system. This refers to the memories that are associated with odors and emotional

In this week’s we got to take a look at an article called Learning to Move by Karen E. Adolph. In this article she talks about the discovering of moving for babies. She states that infants must cope with variable and novel conquering gravity infants must cope with variable and novel constraints on balance and propulsion. Before reading this article I wanted to know about how infants are able to cope with the ability to move and learn about flexibility and specificity. In her article she wanted to
