Brain-derived neurotrophic factor - Wikipedia, the free encyclop Brain-derived neurotrophic factor, also known as BDNF, is a secreted protein[2] that, in humans, is encoded by the BDNF gene.[3][4] BDNF is a member of the "neurotrophin" family of growth factors, which are related to the canonical "nerve growth factor", NGF. Neurotrophic factors are found in the brain and the periphery. Function[edit] BDNF acts on certain neurons of the central nervous system and the peripheral nervous system, helping to support the survival of existing neurons, and encourage the growth and differentiation of new neurons and synapses.[5][6] In the brain, it is active in the hippocampus, cerebral cortex, and basal forebrain—areas vital to learning, memory, and higher thinking.[7] BDNF itself is important for long-term memory.[8] BDNF was the second neurotrophic factor to be characterized after nerve growth factor (NGF). Tissue distribution[edit] Counterintuitively, BDNF is actually found in a range of tissue and cell types, not just in the brain. Mechanism of action[edit]

The solution? A virtual private network, or VPN. A VPN extends your own private network into public places, so even if you’re using Starbucks' Wi-Fi connection, your Internet browsing stays encrypted and secure. There are plenty of ways to set up a VPN, both with free and paid services, but each solution has its own pros and cons, determined by the way the VPN provider operates and charges and the kinds of VPN options it provides. The easiest and cheapest solution to keep your data safe is to just abstain from public Wi-Fi completely. My Raspberry Pi is about the size of a smartphone, but it runs a fully functional VPN server. This is the part where I’d link you to a handy tutorial on how to set this up. Materials Hardware Raspberry Pi Model B: Plus everything that comes with it—by that, I mean a regular power source and a case to put it in. Software .

Itineraries in Florence San Lorenzo Chapel and Santa Maria Novella San Lorenzo is one of two churches in Florence by Brunelleschi. He adopted a simple geometry to develop complex spatial patterns, which can be seen inside the church as well as in the old and new Sacristies; designed by Brunelleschi and Michelangelo respectively. This is a chance to compare masterpieces from the early and high Renaissance. The church has one more treasure: Michelangelo's Laurentian Library, located in the adjacent cloister, which is famous for its entry vestibule, where Michelangelo inserted a stairway that seems to float down from the second floor reading room. If you have enough time you can go to Santa Maria Novella, a Gothic church with a Renaissance facade added by Alberti in the 15th century.
