... and the ripples are waves of sensory perception seen in an EEG reading of cortical activity. When the pump is on and moving at different speeds, the ripples on the surface of the pond are active and take on different coherent patterns; w...

... of consciousness. By deconstructing systems of perception and memory, Psychedelic Information Theory quantifies the limits of expanded consciousness and describes the methods by which psychedelics alter consciousness, create new information, and a...
... diverse fields of pharmacology, shamanism, and perception. As a succinct yet comprehensive formal analysis of hallucination and shamanic ritual, Psychedelic Information Theory (PIT) is destined to become the modern textbook on psychedelic phenomen...

... Donoghue 1993), and in parietal areas engaged in perception with that in frontal areas engaged in planning strategies for action (Tononi et al. 1992; Lumer et al. 1997). Corticocortical connections undoubtedly play a prominent part here as well but ...
5-HT2A Agonism and Multisensory Binding
... real-time binding of sensation to multisensory perception, affective behavior, and the process of consciousness. 5-HT2A receptor mechanics The 5-HT2A receptor is a G protein-coupled receptor (GPCR), which means it does not activate ion channels ...
... psychoactive substances that powerfully alter perception, mood, and a host of cognitive processes. They are considered physiologically safe and do not produce dependence or addiction. Their origin predates written history, and they were employed ...
Crude cognitive schematic of waking consciousness
This is a simple schematic of human cognitive workflow that follows perceptual signal through the brain. Starting at the left with the two inputs (audio and visual) you can chart the flow of signal through the various processing levels until you ulti...

The Case Against the Spirit Model of Psychedelic Action

... is still no appropriate model for textures. The perception of textures as opposed to edges depends upon local but not pointwise properties. However, there is no predefined neighborhood size over which textures can be analyzed. This has motivated...
The visible spectrum is the portion of the electromagnetic spectrum that is visible to (can be detected by) the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light. A typical human eye will respon...
