Document Summary
Chapter 2: cognitive neuroscience: cognitive neuroscience: study of physiological basis of cognition. 19th century, brains inner works beginning to be discovered: nerve network: continuous high-way like system for brain signals (now visible under microscope when stains applied) Golgi (1870s) developed a brain staining technique where less than 1% cells could be stained separately. Caval, used golgi"s technique and the study of baby animal brains to discover that cells were individual units, neurons: neuron doctrine: idea that individual cells transmit signals in the nervous system not continuous). Adrian was able to record electrical signals from single sensory neurons (allowing us to learn about nature of neuron signals: neurotransmitters: chemical released at the end of the axon that transmits the signal across the synaptic gap. Adrian experimented on neuron firing and sensory experience by measuring firing as he put more and more pressure on the skin.
