[70] [71] [72] The first permanent ARPANET link was established on 21 November 1969, between the IMP at UCLA and the IMP at the Stanford Research Institute. By 5 December 1969, the initial four-node network was established. Elizabeth Feinler created the first Resource Handbook for ARPANET in 1969 which led to the development of the ARPANET ...
In 2007 the concept of the default mode was criticized as not being useful for understanding brain function, on the grounds that a simpler hypothesis is that a resting brain actually does more processing than a brain doing certain "demanding" tasks, and that there is no special significance to the intrinsic activity of the resting brain.

[nb 2] After approval by Barry Wessler at ARPA, [11] who had ordered certain more exotic elements to be dropped, [12] it was finalized in RFC 33 in early 1970, [13] and deployed to all nodes on the ARPANET in December 1970. [14] [15] NCP codified the ARPANET network interface, making it easier to establish, and enabling more sites to join the ...
Working with the government, they had cracked the code for computer communications, creating the first and most basic form of the internet, known back then as the ARPANET.
The Interface Message Processor (IMP) was the packet switching node used to interconnect participant networks to the ARPANET from the late 1960s to 1989. It was the first generation of gateways, which are known today as routers. [1] [2] [3] An IMP was a ruggedized Honeywell DDP-516 minicomputer with special-purpose interfaces and software. [4]
Dementia is a general term in the same way that heart disease is a general term. Dementia is caused by damage to brain cells. This damage interferes with the ability of brain cells to communicate with each other. When brain cells cannot communicate normally, thinking, behavior and feelings can be affected. [110] There are many signs of dementia.
Oligodendrocyte formation in the adult brain is associated with glial-restricted progenitor cells, known as oligodendrocyte progenitor cells (OPCs). [15] Subventricular zone OPCs are activated and then migrate away from germinal [ 15 ] zones to populate both developing white and gray matter , where they differentiate and mature into myelin ...
Very large interconnected networks are called large scale brain networks, and many of these together form brains and nervous systems. Signals generated by neural networks in the brain eventually travel through the nervous system and across neuromuscular junctions to muscle cells, where they cause contraction and thereby motion. [2]
