Lecture: key properties of ltp / comparison to tone fear conditioning. Key properties of ltp / comparison to tone fear conditioning. Animals condition to the specific frequency of the tone that was associated with the shock, but not to other frequencies. The acquisition of tone shock conditioning is critically dependent on the two inputs co-occurring in time. The tone input is weak and requires the shock input to drive memory formation. Tone fear conditioning can last for at least one year in rodents, which live. Divisions of the human brain on average only 2+ years. The brain is highly modular with certain regions have specialized functions. Specific brain region interactions produce behavior, perception, thoughts, memories and actions. Different brain regions interact to form functional brain networks. A major goal of modern neuroscience is to understand the nature of these brain network interactions across different behaviors, and how these interactions are disturbed by neuropsychiatric disorders or neurological disease.
