Epigenetic silencing of tumour suppressor gene p15 by its antisense RNA.

abstract：:Midbrain dopamine neurons are activated by reward or sensory stimuli predicting reward. These excitatory responses increase as the reward value increases. This response property has led to a hypothesis that dopamine neurons encode value-related signals and are inhibited by aversive events. Here we show that this is tr...
