PS101 Lecture Notes - Lecture 4: Efferent Nerve Fiber, Central Nervous System, Myelin
Document Summary
Standard deviation is an index score based on the distribution. Correlation is about prediction, it"s about taking two variables and comparing a to. Tells us where, in relation to the population, the score falls. Tells us how likely the score is to occur. B with predictions, not about background or how. Atlas shows how sophisticated our brains really are as we do very little everyday things without thinking with mental processing. We have 80 100 billion neurons in the average human brain. 3000x a mac in our brains of computing power. Specialized cells that carry messages throughout the nervous system. Comes in all different shapes and sizes. Like the glue that holds neurons together, preform various support structure. Can in some cases (cid:498)act like a neuron(cid:499) Afferent neurons (sensory) (incoming) relay information from the sense to the. Efferent neurons (motor) (outgoing) send information from the central nervous.
