However, we've yet to establish much presence when users require olfactory information - such as in environments focused on foods, flowers, perfumes, or, in some cases, more offensive smells.(More)
In an experimental study using adult cats, we analyzed the distribution of the sympathetic postganglionic neurons in the superior cervical ganglion (SCG) which innervate the pupillary dilator and tarsal muscles to determine whether there are direct fiber projections from the spinal cord to the iridic and tarsal muscles. This study consisted of three(More)
It is generally accepted that preganglionic neurons of the cervical sympathetic nerve arise from the ciliospinal center, which exists in the spinal cord over C8-T3. However, its distribution within the spinal cord has not been exactly demonstrated. Therefore, horseradish peroxidase (HRP) was injected into the cervical sympathetic trunk in order to(More)
