... in psychedelic study, drew him to my attention. What struck me was his intuitive intelligence and objective queries. He was also then working on his book, and many like myself, witnessed its laborious evolution through many stages of edi...
... a small amount of the substance and paying close attention to the interference patterns created in perception; that shamanic icaros or standing vocalizations are produced in response to interrupt frequency and ADSR envelope to drive or dampen the am...
5-HT2A Agonism and Multisensory Binding
... to the cortex. These loops can be described as attention-controlled feedback filters which drive and stabilize external perception and behavior. CSTC loops provide real-time sensory feedback for fine-tuning eye movements, motor reflexes, emotional...
Group Mind and Fluid Tribal Dynamics
... group mind. You must first demand focus of group attention, and then you must masterfully apply the entrainment technology; these rules are immutable and are the same for the hypnotherapist, the shaman, the musician, the salesman, the politician, th...
... differences in ability to focus and maintain attention, particularly when other events are serving to capture attention. These effects seem to be a function of frontal brain areas.[33] Others have argued that the capacity of working memory is...
... encouraged to close their eyes and direct their attention inward. At the 14-month follow-up, 58% and 67%, respectively, of volunteers rated the psilocybin-occasioned experience as being among the five most personally meaningful and among the five...

An Overview of Physical Shamanism
... is intuitive if the shaman merely pays close attention to his or her internal physiology as the hallucinogen takes action. In the nomenclature of chaos theory, when a chaotic system evolves towards a particular state over time, that state is ca...
An Interview with Dave Nichols
... were looking for. We have focused most of our attention on the diethylamide, because the potency of LSD is so exquisitely dependent on what that amide is. We've made a lot of compounds that we haven't even published data on. We have receptor bind...
... L-DOPA and is instrumental in modulating salient attention, motivational response, and fine motor control. Dopamine is central to the reward system, and dopamine release is stimulated by recreational drugs, food, gambling, sex, and physical risk tak...
Does time dilate during a threatening situation?
... properties which require an increased amount of attention to be devoted to it. Alternatively, the perceived duration of the stimulus might reflect the amount of energy expended in generating its neural representation (that is, duration is a functio...

Bypassing interneurons: inhibition in neocortex
A recent paper suggests a new form of inhibitory circuit in cortex, in which a pyramidal cell directly excites the presynaptic terminal of an inhibitory interneuron, allowing the rapid and powerful inhibition of another pyramidal cell....
Scientists explain inception of perception in the brain
The taste of champagne, the sound of a train, the flash of a pop fly into left field – indeed all of human perception – begins in the brain’s center. That’s where sensory information passes from the thalamus to the neocortex for proce...
Cortical Region Interactions and the Functional Role of Apical Dendrites
The basal and distal apical dendrites ofpyramidal cells occupy distinct cortical layers and are targeted by axons originating in different cortical regions. Hence, apical and basal dendrites receive information from distinct sources. Physiological ev...
Timewarp: How your brain creates the fourth dimension

Increasing evidence suggests a link between attention, working memory, serotonin (5-HT) and prefrontal cortex activity. In an attempt to tease out the relationship between these elements, this study tested the effects of the hallucinogenic 5-HT1A/2A ...
Psilocybin slows binocular rivalry switching through serotonin modulation
... binocular rivalry switching rate to arousal and attention and suggests that psilocybin induced slowing of binocular rivalry is not 5-HT2A mediated, but instead may reflect a 5-HT1A mediated reduction of serotonin release from the brainstem raphe nu...
