Unformatted text preview: Cellular Mechanisms of Cognition o Cellular components of the brain Will focus on the cellular anatomy and physiology of neurons Give us a basic understanding of the complex events that underlie what we see at the behavioral level o Structure of the neuron Neurons Basic signaling units (many different types with different shapes and sizes) Typical features Most are both pre (sending signal) and post-synaptic (receiving signal) Cell body o Contain mitochondria, golgi bodies, ribosomes, ER, nucleus Axon (receives signal) Dendrite (sends signal) Signals are electrical within, and chemical between Voltage changes may result in neurotransmitter release White matter: axons Gray matter: cell bodies and dendrites Neuron Doctrine Neural units o Thought to be individual units o Function on their own o Problem: most neurons dont typically function like that Connectional specificity o Specific neurons work in specific tasks Dynamic polarization o White matter runs through the core of the brain and terminate...
