Document Summary

Lc innervation of paraventricual nucleus of the hypothalamus (pvn paraventricular nucleus) Ne or apha2 receptor agonists injected into the pvn stimulates eating response; effect is blocked by alpha2 antagonists. Electrophysiological and pharmacological evidence for a role of central ne in processing arousing sensory stimuli. Activity of lc neurons changes with behavioural state of animals. Activated by arousing stimuli and inhibited during sleep. Microinjections of alpha or beta receptor agonists into the medial septum increases animals" time spent awake. How peripheral and central epi and ne are integrated at some level in the brain. When we acquire information, that information is encoded in the neural circuitry of the brain, it is in a fragile state in short-term memory the synaptic and behavioural level) it will not be stored in long-term memory circuitry. Emotionally charged memories are often the best consolidated, longest lasting and most vibrant. Information can be displaced based on the emotionality of that information.
