Moreover, we discuss how the contribution of dendrites and axons to neuronal excitability may impose constraints on the morphology of these compartments in specific functional contexts. More than a century ago, Santiago Ramon y Cajal provided us with a tremendously extensive description of the various morphologies of the neuronal types constituting the mammalian brain and other species’ nervous systems ( Cajal, 1952). From this meticulous observational work, Cajal hypothesized the role of the different neuronal compartments in information processing. One of his most famous contributions in that sense was the law of “dynamic polarization” that originally stated that, within a neuron, information is transmitted from the dendrites towards the soma (cellulipetal) and then in the axon away from the soma (cellulifugal). However, noticing the morphological peculiarities of several neuronal types, Cajal soon revisited this law, because it could only fit neuronal types where the axon directly arose from the cell body onto which all dendrites converged. S Pen support makes perfect sense on a screen of this size, and it was something that people were clamoring for with the first two Folds.In particular, Cajal made the observation that in many invertebrate neurons and even in some vertebrate neuronal types (such as the crook-shaped cell in the optic lobe of birds), the axon arose from a dendrite, hence compromising the theory of cellulipetal and cellulifugal propagation of information. There’s more writing and drawing real estate here than on any Galaxy Note smartphone, yet not so big that it’s inconvenient like a full-sized traditional tablet that has to be stowed in a bag. The Galaxy Z Fold 3 can be closed to half and stuck in a pocket. It may well change the way you use your phone day to day, especially if you spring for the S Pen and a case to carry it in – unfortunately, the stylus is sold separately and doesn’t tuck inside the phone. That inconvenience will be jarring for long-time Note fans, even if we found the new stylus bigger and easier to use than the Note’s toothpick-sized S Pen.Īlso, you’ll need to dial back your camera expectations: this is yet another foldable with cameras that are good, but which lack the zoom-in oomph of the Samsung Galaxy S's Note 20 Ultra. There is one standout camera perk: an under-the-screen camera neatly obviates the need for punch-hole on the more seamless inner display, although the 4MP camera quality loss is noticeable. The big hook to the Galaxy Fold 3 is its slightly cheaper price compared to the Galaxy Z Fold 2. Samsung Galaxy Z Fold 3 release date and price Our hands on Samsung Galaxy Watch 4 Classic review.Those who had their doubts about the first two generations of Samsung’s foldable, were right to hold ‘em, but now it may be time to fold ‘em, as this truly is one of the best Samsung phones, and will likely still remain a worthwhile machine, event when its successor, the Galaxy Z Fold 4, arrives. The best Samsung Galaxy Z Fold 3 deals in your region.It starts at $1,799 / £1,599 / AU$2,499 for a model with 256GB of storage, while if you want extra capacity you can get a 512GB Galaxy Fold 3 for $1,899 / £1,699 / AU$2,649. The Samsung Galaxy Z Fold 3 retains the book-like design and functionality of its two predecessors, with a limited but usable 6.2-inch Cover Display on the outside of the handset that opens up to reveal a massive 7.6-inch display on the inside. The two displays, and a hinge mechanism that allow you to fold and unfold this phone, combine for the most head-turning mobile gadget design of 2021. Yes, we’ve seen it twice before, but most people we showed the Galaxy Fold 3 to still haven’t seen anything like it.Īnd that’s what you’re paying for: the wow factor of being able to pull a phone out of your pocket and unfold it to not only reveal a 7.6-inch tablet-like display, but to also show that you're symbolically ahead of the technology curve. Samsung has made improvements to the hinge, and the materials used are more durable than those employed in all previous foldable phones we've tested. In fact, Samsung is claiming the Z Fold 3 is 80% stronger than its prior foldables and sure enough, there’s a noticeable difference when you unfold the device, especially if you’re upgrading from Gen 1. It’s sturdier than the Fold 2, and the company’s Ultra Thin Glass feels less mushy this time around – that’s important whether you’re playing games or swiping through Instagram and TikTok videos. The Z Fold 3's design is remarkable, even if it doesn’t always seem practical.
