You misunderstood.
I think that Perception+Olfactory Booster would be a bad choice, because there are no tests that are Skill+Modifier. I would allow it to be Intuition+Booster, or Intuition+Rating in Enhanced Sense.

As for Improved Senses, I would say that they could be tracked and noticed, but since it states that strong smells induce penalties on the power, that it could not be used in defense of Tailored Pheremones.

EDIT: I would actually go so far as to say that Adepts with enhanced senses would be more affected by Tailored Pheremones, since their powers are always active...hmm...perhaps always suffering the effects of a distracting odor (-2D) as is stated under Perception tests.

Just be sure to hold outside meetings on days when the Smog Air Quality Index is in the Red Zone.

That's true...perhaps allowing the Olfactory Booster user to decrease the dice given by the person with Enhanced Pheremones?

Though, Lone Star walking around with Pheremone Scanners to find people with the felonious bio-enhancment would be a funny sight.

"Sir, would you care to explain why you are registering as a hot spec on my radar."
"Yeah...I had an accident a long time ago, um...and had to get...stuff...put...right..."

As another point, about an Adept with Kenesics who chooses to shut down or override his bodies response to the Pheremones? While it gives him additional dice, would it penalize the person with Enhanced Pheremones?

Pheromone are not necessary nice smells that's sure.
But you are are wrong : they are not at all like toxins.

They are detected (chemical receptor) by the nose, the signal is then integrated by the brain, which order part(s) of the body to react in a certain way.

So yes ! if you cut the signal going from the nose to the brain, pheromones won't have anymore effects.

Don't underestimate the power of the smell !!!

I do not like intuition alone for a adept with improved smell (and without enhanced senses) actually.

For the rest I think you are right : you can't "cut" improved smell as the cyber enhancement thus it won't help against pheromone. It may help to detect them.

Uncough adept will surely go on speaking with their Johnson while putting on their gas mask !

Indeed, you can. As the write-up says it follows the rules for 'Sniffers listed earlier in the book. And, of course, Pheremone 'Sniffers allow you to detect Tailored Pheremones with a Thershold 2 test.

So the VNO doesn't seem to be linked to the conscious sense of smell. The olifactory epithelium (the sense-of-smell bits) is wired to the olifactory cortex (the bit that distinguishes and catalogs scents). The VNO is wired to the amygdala (a thingy that stimulates memory) and the hypothalamus (the bit that regulates hormones, which in turn regulate behavior). There seem to be two paths, and so little or no connection between the two functions.

I agree with this, because I can smell pheromones. It's a lame super power, I know, but a highly sensitive sense of smell runs in my family (I have another stupid super power, too, but it's not germane). I can smell people's moods, where a woman is in her cycle, and whether a woman is interested in me. That being said, even though I can smell them and know what the scent means, my mood is still influenced by them.

Two disclaimers:

1. I am not a neurologist.
2. Try not to think about my super power if you ever meet me in person.

The question becomes this: does the olifactory booster replace the VNO (which sits in the bone at the back of the nose, the one you can see in skulls) as well as the olifactory epithelium (which lines the inside of the nose)? Standard biomedical practice advocates the minimum intrusion possible, and so would leave the VNO alone, so that's my vote. I'd allow an olifactory booster a shot at detecting the use of tailored pheromones, though.

Interesting link.

You don't need to replace all the receptor for the nose and sinus to replace them by the olfactory booster anyway.
You just need to link the cyberware to both the cranial nerve for smell - and make the other connection with your commlink. The VNO is "part of the olfactory system(s)" from what is said in the article.

I like that part :

Agreed, but the VNO is part of the olifactory system only because it's, well, olifactory. It's not wired up to the conscious part of the system (that's from the other article, the one that was written later). If you plug the olifactory booster into the olifactory nerve, then the booster isn't connected to the VNO's signals.

Heh. I wonder if the University of Vienna ever checks their logs.
"Hey Karl, we just got two hundred downloads of your paper on Integrating Neuroendocinology from all across Western Europe and N. America."
"Sounds like role-players again, I guess."

What's german for WTF?

English ancronyms are nearly never translated in german.

I hadn't thought about it that way; I just assumed my epithelium-side sense of smell was sensitive. Maybe I've got some near-end cross-talk in my face. =)

I've never tried to describe it before. It's kinda like describing a color; you know what "green" is, but you can't really explain it. I suppose it's kinda germane to the topic, so I'll give it a go, despite the fact that I wonder if I'm not just serving as a freak show. =b

I'll start out by saying that there is a certain amount of difference between people. One woman's aroused scent, for example, is not exactly the same as another's. In fact, sometimes I can actually identify people by their scent. Still scents are similar. Arousal smells kind of like a light musk with a bit of baby powder mixed in, for women. Fear is similar, but less baby powder and more acidic. Depression doesn't smell like much, it's like a dampened normal scent. A woman who is on or about to get her period smells like the musk, only with a little more tanginess to it; sometimes the scent of feminine hygiene products covers it up a bit, so sometimes it's that and not the actual hormone/pheromone that clues me in.

The irony of this post is that I am completely stuffed up right now, and can't actually smell a thing. I love irony.
