Ventrobasal thalamus necessary for visually-released defensive boxing of rat.

摘要: Abstract Visually-released, pain-induced defensive boxing in the rat was abolished by lesions which destroyed ventrobasal thalamus. The visually-released produced facial anesthesia of one a pair rats were administered footshock small chamber; with forced to rely upon visual stimuli rather than tactile normally release behavior. abolition specifically related destruction thalamus adjoining structures. A particularly effective control procedure involved response unilateral confined and removal input contralateral side brain closure ipsilateral eye. Since is learned behavior dependent cortex, it would appear that cortical mechanisms incorporate higher levels projection system into an alternative releases after anesthesia.
