Rats that ate during hypothalamic stimulation were trained to press a lever for food only while receiving light signals from head-mounted lights. During stimulation, they pressed if the signal was visible to the eye contralateral to the electrode, but ignored the signal if it was visible only to the ipsilateral eye.
The software needs of psychology researchers are sufficiently diverse that they cannot be met by the commercial sector. The field needs more psychologists who publish software, and individual researchers need to be able to write their own. To support this view, the author offers EL Knife, a data utility for reconfiguring multifactor spreadsheet files. Data… (More)
Grooming occurred as an aftereffect of electrical stimulation at hypothalamic sites that elicited locomotion, drinking, or eating as stimulus-bound behaviors. Removal of food or water, which caused rats to switch from one stimulus-bound behavior to another, produced little or no change in the grooming aftereffect. Stimulation with pulse showed that the… (More)
