    Can someone explain to me about this technology? All this time i thought it was the design at the throat but i was told that it is not, it is built in the handle.

    A piece of plastic that is glued on the racquet. But of course im talking about the GT and older models. The newer Babolats, I.E 2013 APD and 2012 PD have a active cortex. It doesn't seem like it does much, but it clearly looks like a gimmick that should work very slightly.

    My understanding (but I may be wrong) is that Cortex is in the throat, actually:

    http://www.babolat.com/#/tennis/us/innovations/47/Cortex-Active-Technology

    I believe that it's simply an inserted (plastic or silicone?) layer that separates throat and handle shaft, not allowing direct contact and transfer of vibrations between the two.

    It is envisioned as a frequency filter, which supposedly attenuates low frequencies that cause harm to joints, and passes frequencies associated with the "feel" of the ball at impact.

    Whether it works as intended or not, is a different question... :)

    I just hacksaw'd an apdgt, looking through it right now, hollow through the cortex piece. it looks like the cortex is a decorative external piece only. the inside looks just like a hollow one piece all the way down. the gt area as well, looks like a simple one piece, hollow throughout. hollow hoop, hollow throat, hollow handle.

    Technology? Please, then every one with a dampener is a pioneer.

    It's nothing but a gimmick, just like every other "technology".

    sawed through the cortex, its like theres a slight groove on the external surface (minor indention) , the cortex is a piece of plastic that in-sets over that. just on the surface, cut in enough to be semi-flush to the exterior.

    Just a gimmick really. Weight is a true vibration killer

    not necessarily. a clock tower bell weighs a ton, but it rings loud so weight doesn't kill vibration. something that is able to absorb energy like rubber and foam kill vibrations.

    That's not really the same thing. Mass really is the most straight forward way to reduce vibration transmission. In fact, in acoustics, there is the so-called mass law:

    http://rwsc2.inforce.dk/sw98684.asp

    Since sound is produced by vibrations, it's still analogous. A more massive racquet will transmit less vibration at the expense of feel. This is a problem though since weight always has a negative aspect.

    Helps explain why the pdr has little to no feel

    Doesn't explain why the previous generations has little to no feel.

    there was one more specific cortex pic but it was unfocused.

    So that's famous "Cortex technology"... I'm impressed ;)

    maybe it feels hollow but basically it's sort of a nice idea to ease some vibrations IMO.
    not sure if other brand's ideas looks much 'cooler' once you slice them.

    Don't get me wrong, I'm a Babolat owner (Pure Drive GT 2012).

    On my racquet, Babolat engineers made a huge improvement and even made this plastic-piece "active" by turning it upside-down (V shape -> A shape).

    Since all playtests of Pure Drive 2012 confirmed that the new "active cortex" makes a noticable difference compared to "passive" cortex system, they implemented it in new and improved AeroPro Drive 2013, as well... ;)

    Makes you wonder why they even bother to pj it on Nadals racquet, since it's likley only cosmetic. Roddick just wrapped his overgrip high up the handle so you never saw the fake "cortex".

    As mentioned, it's a bunch of marketing bologna that doesn't do anything at all.

    Wilson, however, produced a line of racquets several years back that actually had a piece of vibration dampening rubber/plastic in between the handle and throat. It worked, but wasn't popular.

    Babolat probably decided to steal the idea, modify it, and market it towards all the people who think stiff Babolat racquets are the cause of their elbow and shoulder issues...

    I thought the original idea belongs to Head with its Suspension Grip. Which actually had an internal apparatus inside the grip that spins/rotate/move to dissipate the shock of the frame? It just breaks all the time that's all.
