The Journal of neuroscience : the official journal of the Society for Neuroscience.J Neurosci.2015 Nov 4;35(44):14809-21. doi: 10.1523/JNEUROSCI.2285-15.2015.
We were interested in determining whether rostral medial prefrontal cortex (rmPFC) neurons participate in the measurement of conditioned stimulus-unconditioned stimulus (CS-US) time intervals during classical eyeblink conditioning. Rabbits were conditioned with a delay paradigm consisting of a tone

We have previously characterized a model of posttraumatic stress disorder (PTSD), based on classical conditioning of the rabbit nictitating membrane response (NMR), that focuses on 2 key PTSD-like features: conditioned responses to trauma-associated cues and hyperarousal. In addition to the developm

Importance of social stimuli for the development of learning capability in honeybees

… However, in a proboscis-extension reflex (PER) assay, newly emerged and very young worker bees could not associate a given odor (conditioned stimulus, CS) with a sucrose reward (unconditioned stimulus, US): This ability was acquired 5 to 9 days after emergence in workers, while it was accomplished 2 to 5 days after emergence in drones, probably reflecting the earlier onset of flight in drones. …

学習の中で最も基本的な条件付けの一つとして古典的条件付けがある.本研究では,古典的条件付けに基づく条件付け味覚嫌悪反応(CTA)が海馬,大脳皮質味覚野においてどのような情報処理がされているのか微小電極を用いて調べた.刺激には,条件刺激(CS)にスクロース無条件刺激(UCS)に塩化リチウムを用いて条件付けを行った.その結果,条件付けされる前と後において大脳皮質味覚野での活動が見られた.
