The Other Side of Dr. Xeno's Brain

It's me, Dr. Xeno. Here are lecture notes and ideas for my work teaching physical and cognitive development across the lifespan (HDEV 3101) at the Department of Human Development at CSU, East Bay. This content is often referred to as mind-brain, mind body connection, brain and behavior; but it is really about the knowledge derived from the related fields of neurology, neuropsychology, neuroscience and cognitive science. Sometimes I just write about my kids or bike racing. Feel free to comment!

Why don't we see upside down?

Major parts of the visual system. Note that the lens in the eye flips the image upside down and this orientation is carried through the system's pathway all the way to the visual cortex (back of the brain) Primary visual cortex is where we have our first conscious awareness of visual input and that input is further processed (decoded) in secondary and tertiary visual cortices (most senses are set up with these 'tiers' of processing in subsequent neighboring cortical zones).


Do we see the world upside down? Nope, we quickly adapt to this image flip - and this makes the point that the neural code is simply neural energy representing information and NOT the information itself (and certainly not the 'thing' itself).

We are InfoVista...


I won't be too surprised if some folks still refer to the team as 'Documentum' even in 08. But, for 2008 and probably beyond 2009, the East Bay Cyclists club's race team shall be named for the generous sponsor InfoVista. Uh, network service... I mean network security... something important, I'll get better at this. Anyway, this is but a minor change in the NorCal racing scene.

There will still be a team named EMC
2 and we (I?) wish them the best of luck sluggin it out in the upper echelon of NCNCA racing. Wonder what colors they'll select? What with Hootie, Sasser and lord knows who else joining th eZebratic Jesster, I finally have to ask: whatexactly is a VOS anyway? Will Morgan Spinal 24 Hour Specialized add some green to their kit? Speaking of green, will BPG come through for another year of title sponsor cash for the RHVillans? Will VSRT add a few more racers and make an impact? Will the blue dots continue their solid growth and dominate all categories? Why don't Synergy guys wave back? (Except for you Andreas, thanks again for the tube.) And finally, will the Peggy's have another color mishap that accidentally improves the look of their kit again for 08?

Well, look for us InfoVistas in the familiar spidey-like carbon-weave kit on the road and in the dirt and even in some multi-sport type events. Now, get back to your winter training; or eating.
