PSYC62H3 Chapter Notes - Chapter 2: Caudate Nucleus, Pineal Gland, Stimulant
Document Summary
A railway construction foreman who survived an iron pole through his skull. But after the accident his behavior radically changed from kind, reliable, and friendly man to someone who was fitful and someone who engages in gross profanity. This incident shows that ones personality can dramatically change from injury to the brain. The study of psychoactive drugs requires knowledge about how drugs act on the nervous system. The brain contains a dense ensemble of neurons and glial cells. Neurons these are specialized cells in the nervous system that control behavior, sense, and movement. Neurons communicate by receiving and transmitting information to other neurons in the nervous system and the body. Glial cells these support the function of neurons. Neurons comprise dense communication networks in the brain. These networks support the function of individual brain structures and facilitate communication between structures. Neurons have four major components a soma, dendrites, axon, and axon terminal. The soma is the body of the neuron.
