Document Summary

Scientific study of links between biological and psychological processes. Neuroscience; behavioral genetics; evolutionary psychology; behavioral microbiology. We can make changes to our brain based on day to day tasks, what we learn (can actually have significant impact on physical brain not only mental) Allow communication to be faster insulating layer of fatty material. Helps efficient transmission of signals to other cells. Gaps in myelin sheath are nodes of ranvier- to get to other end quicker. Question the speed at which a neural impulse travels along the axon is greatly impacted by: The presence of myelin sheath ( can affect the speed at which the neural impulse can travel down the axon) Neurotransmitter a specialized nerve cell that receives, processes, and transmits information to other cells in the body ( neurons do not regenerate) Resting potential neuron is negatively charged at rest (-70 mv), depolarization to + 35 mv. When an action potential happens we get a rapid depolarization.
