Spontaneous activity is brain activity in the absence of an explicit task, such as sensory input or motor output, and hence also referred to as resting-state activity. It is opposed to induced activity, i.e. brain activity that is induced by sensory stimuli or motor responses. The term ongoing brain activity is used in electroencephalography and magnetoencephalography for those signal components that are not associated with the processing of a stimulus or the occurrence of specific other events, such as moving a body part, i.e. events that do not form evoked potentials/evoked fields, or induced activity. Spontaneous activity is usually considered to be noise if one is interested in stimulus processing; however, spontaneous activity is considered to play a crucial role during brain development, such as in network formation and synaptogenesis. Spontaneous activity may be informative regarding the current mental state of the person (e.g. wakefulness, alertness) and is often used in sleep research. Certain types of oscillatory activity, such as alpha waves, are part of spontaneous activity. Statistical analysis of power fluctuations of alpha activity reveals a bimodal distribution, i.e. a high- and low-amplitude mode, and hence shows that resting-state activity does not just reflect a noise process.[43] In case of fMRI, spontaneous fluctuations in the blood-oxygen-level dependent (BOLD) signal reveal correlation patterns that are linked to resting states networks, such as the default network.[44] The temporal evolution of resting state networks is correlated with fluctuations of oscillatory EEG activity in different frequency bands.[45]

There is nothing more mysterious than a TV set left on in an empty room. It is even stranger than a man talking to himself or a woman standing dreaming at her stove. It is as if another planet is communicating with you. Suddenly the TV reveals itself for what it really is: a video of another world, ultimately addressed to no one at all, delivering its images indifferently, indifferent to its own messages (you can easily imagine it still functioning after humanity has disappeared).

"Radio engineers have been interested by several recent incidents of mysterious music coming from articles to which no radio receiver is attached"
The idea of using VGA adapters as a transmitter has a long history. In 2001 Erik Thiele released Tempest for Eliza, which transmits a signal that can be received with an AM radio. In 2005 Fabrice Bellard used an ATI Radeon 9200SE to transmit DVB-T, PAL and NTSC video signals. Later in 2009, Bartek Kania published VGASIG, which allows to transmit wideband FM radio in realtime using SDL and a regular graphics card. In 2013, siro at das Labor used all three DAC outputs of a VGA card and attached an I/Q modulator to transmit arbitrary signals. However, a major downside with regular graphics cards is that the generated signal of the RAMDAC is not entirely user controllable, as VGA uses horizontal and vertical blanking, thus interrupting the signal. In comparison to competitor devices from DisplayLink, which resemble a classic graphics card with USB 2.0/3.0 interface, Fresco Logic took a different approach for their USB to VGA adapter, which they've also patented. Instead of having the framebuffer for the VGA DAC in the device itself, they use the memory of the host computer and continuously stream the display content via USB. This makes such adapters very cheap, as it essentialy reduces the adapter to a single chip without requiring framebuffer memory. The main drawback is that if the host CPU or USB bus is busy or congested, this results dropouts and flickering of the screen. After reverse-engineering the USB protocol of the FL2000 in 2016, Steve Markgraf discovered through experimentation that it is possible to operate the FL2000 in a way that both horizontal and vertical synchronization are disabled, thus creating a continous stream of samples. This work resulted in osmo-fl2k, which so far was used to transmit low-power FM, DAB, DVB-T, GSM, UMTS and GPS signals.
As part of its ongoing psychic research in the '80s, the Central Intelligence Agency explored the ideas of notorious "free energy" advocate Tom Bearden, according to one of Bearden's papers discovered in the CREST archives by Mike Lewinski. In particular, the Agency was interested in "STAR WARS NOW!," Bearden's warning of Soviet weaponization of electromagnetic fields to create superweapons such as the "Tesla Howitzer."
