Immediate and Long-Term Effects of Septal and Frontal Ablations on the Species-Typical Behavior of the Rat

Part of the Advances in Behavioral Biology book series (ABBI, volume 20)


It has been accepted that the role of the septum is that of being part of the neural substrate for mediation and expression of behavior’s emotional or motivational component (24). For the most part, explanations of this role have been couched in descriptors connotating emotional behavior which should be recognized in gross behavioral displays. Examples of such terms are hyper-emotionality (18,30,48), rage reactions (14,15), increased or hyper-reactivity (36), hyper-activity (25,38), hyper-sensitivity (33,52), increased boldness (30,58,62), disinhibition (27,42,50), decreased fear (50,53), and altered species-specific defense reactions (2,54,48,56,59).
