Visual stimuli occurring naturally are rich in instances of objects delineated from the backgrounds only by differences in luminance,which is called first-order stimuli,as well as those defined by differences of contr...

Since Levick et al. found and studied the orientation biases of retinal ganglion cells of cats, there has been increasing interest in subcortical orientation sensitivity. Shou et al. studied the orientation sensitivit...

Among the visual cortex areas investigated, besides areas 17, 18 and 19, the lateral suprasylvian area (LS) is best studied. The cells in this area are mainly sensitive to the visual stimuli with the preferred moving ...
It is generally accepted that the parasympathetic preganglionic neurons are cholinergic. However, in our laboratory it has been observed that the acetylcholinesterase (ACHE) positive neurons could not be seen in the a...
Ⅰ.INTRODUCTION In our previous work, we found that the nociceptive response of spinal dorsal horn neurons to peripheral stimulation could be reduced by acupuncture of bilateral Zusanlipoints (St 36). This paper is de...
In guinea-pigs, cats and dogs, 4-R-2,2,5,5-tetracis (trifluoromethyl)-imidazoline (R =NHCH2OCOCH3, throughout this paper the term 'SIS-Ⅱ' refers to this derivate) has been shown to induce stepping movements toget...
The medial hypothalamus is implicated in the regulation of adenohypophyseal secretion as well as in the integration of feeding, emotion and autonomic functions. Recently, many authors have reported that the hypothalam...
During the period of 1981--1982, on the basis of previous work, we continued the investigation of toxoplasmosis on domestic animals in Beijing area and 3 strains of Toxoplasma gondii were isolated from the local cats ...
