Firstly that pyramidal cell axons (with the exception of the drum stick like branches of layer 6 cortico-thalamic pyramidal axons in layer 4, Zhang and Deschênes, 1997), run almost straight through the neuropil, deviating significantly only as they encounter large obstacles, like blood vessels.

More than 40 HPV types can be easily spread through direct sexual contact, from the skin and mucous membranes of infected people to the skin and mucous membranes of their partners.
They can be spread by vaginal, anal, and oral sex (1).
Around one-half of these infections are with a high-risk HPV type (6).
Most high-risk HPV infections occur without any symptoms, go away within 1 to 2 years, and do not cause cancer.
Homeostasis in a general sense refers to stability or balance in a system.
This adjusting of physiological systems within the body is called homeostatic regulation.
Homeostatic regulation involves three parts or mechanisms: 1) the receptor, 2) the control center and 3) the effector.
Anyone who has spent hours at the microscope, reconstructing cortical axons at high power, will be aware of the immense complexity of these axonal arbors and their huge diversity.
A number of anatomical properties become apparent very rapidly. Complementary expressions of transcripts encoding GAD67 and GABAA receptor alpha 4, beta 1, and gamma 1 subunits in the proliferative zone of the embryonic rat central nervous system.
