Plasticity of mystacial fur representation in SI cortex of adult vibrissectomized rats--a 2DG study.
Localization of cortical representation of the common fur of mystacial pads was mapped with 2-deoxyglucose autoradiography in adult rats after vibrissectomy. Normal representation of mystacial fur was found in locations outside the posteromedial barrel subfield (PMBSF). Vibrissectomy performed in young adult resulted in fur inputs activating the PMBSF. This plastic change took more than two weeks and less than one month to complete.
