Purpose: We have previously shown that the stimulation of limbic structures related to affective life such as the amygdale can improve and reinforce neural plastic processes related to hippocampus-dependent forms of explicit memory, as spatial memory and LTP. We now assessed whether this effect is restricted to the mentioned structure and memory type, or represents a more general form of modulatory influence.
Methods: Young, male Sprague Dawley rats were implanted stereotactically with one electrode in the basolateral amygdala (BLA) and trained to acquire a motor skill using their right anterior limb.
