Individual behavioral responses to hypothalamic stimulation persist despite destruction of tissue surrounding electrode tip
(Elsevier, 1979-09)
Behavior evoked by hypothalamic stimulation differs among animals, although their electrode placements appear histologically to be identical. These differences have been attributed to selective activation of functionally ...
Hormonal induction of behavioral estrus modified by electrical stimulation of hypothalamus
(Elsevier, 1972-07)
Sexual receptivity was induced by sequential injections of estrogen and progesterone in ovariectomized female rats which had bilateral, monopolar electrodes permanently implanted into either the medial preoptic area (MPOA) ...
Lateral spread of light adaptation in the rat retina
(Elsevier, 1977)
Recordings from the rat optic tract fibers were used to assess changes in sensitivity under various conditions of adaptation. An adapting background which excites only a small fraction of the rods can yet cause a several-fold ...
Individual differences in sexual responsiveness to estrogen and progesterone in ovariectomized rats
(Elsevier, 1972-04)
Individual differences among 83 ovariectomized rats in behavioral responsiveness to estrogen were measured by scoring the quality of sexual receptivity induced by injections of estradiol benzoate (EB) and progesterone (P). ...
Single retinal ganglion cell responses in the dark-reared rat: Grating acuity, contrast sensitivity, and defocusing
(Elsevier, 1978)
The visual acuity, refractive state, and depth of focus of the dark-reared hooded rat's dark-adapted eye were determined by recording the responses of retinal ganglion cell axons in the optic tract. The smallest square-wave ...
