PS101 Study Guide - Final Guide: Ependyma, Schwann Cell, Resting Potential
Document Summary
Neuroscience: the study of the brain and the nervous system. In the past, researchers strayed away from studying the brain because of limits in our study methods and technologies. It was virtually impossible to study the brain without causing damage to brain tissue. Several decades ago, human neuroscience relied largely on one of the following methods: examining autopsy tissue, testing the behaviour of patients with damage to certain parts of the brain, recording electrical brain activity, animal studies. Types of neurons: afferent neurons (sensory) - relay information from the senses to the brain and spinal cord, efferent neurons (motor) - send information from the central nervous system to the glands and muscles, enabling body to move. Interneurons - carry information between neurons, communicate with both sensory and motor neurons. Resting potential: resting potential is the electrical charge of a neuron when it is at rest.
