Unilateral motor cortex injury in the cat results in a prolonged loss of tactile placing in the forelimb contralateral to the injury. Amphetamine (5 mg/kg) temporarily reverses this tactile placing deficit as early as 4 days following the injury. Racemic amphetamine was found to produce a significan

Intracellular recordings were made from 117 neurons in the motor cortex of anesthetized cats. The pyramidal tract (PT) and VL nucleus of thalamus were stimulated in order to activate the neurons from two directions. 1. PT cells were conditioned by antidromic trains (10--50 cps for 4--15 s) and by pa
## Abstract ## Purpose To investigate whether and how the bloodโoxygenationโlevelโdependent (BOLD) functional MRI (fMRI) signal is modified by brain tumors. ## Materials and Methods The BOLD signal depends on the perfusion, which in turn may be affected in the presence of a tumor. Some studies h
