决策网络必须根据规则进行调整,这些规则决定了当前感觉信息的给定星座将奖励哪些行动。不知何故,这些规则必须在将感官暗示转化为行动的网络中实施,但这种表示的性质是神秘的。最近的发现表明,一些鱼类中与莫特纳相关的网络可以控制令人惊讶的复杂和可塑性的决定,在这些决定中,猎物运动的规则决定了必须选择什么速度和方向才能在正确的时间出现在正确的地点。随着关键的细胞参与者可以单独识别,FISH可以帮助我们发现脊椎动物大脑决策电路中规则如何表示的本质。
Decision-making networks must be tuned according to the rules that govern which action will be rewarded for a given constellation of current sensory information. Somehow these rules must be implemented in the networks that translate the sensory cues to actions but the nature of this representation is enigmatic. Recent findings suggest that Mauthner-associated networks in some fish can govern surprisingly sophisticated and plastic decisions in which the rules of prey motion govern what speed and direction must be selected to be at the right point at the right time. With the key cellular players individually identifiable, fish can help us to discover the nature of how rules are represented in decision-making circuitry of the vertebrate brain.
