Why Do Psychedelics Alter Time Perception? The Neuroscience Explained By Goncalo V. Time perception is potentially one of the most present skills in our day to day, we’re constantly aware of time during our circadian routine, whether it’s to enter our routine or finish our day, yet this is only part of what time perception actually does in our life, time perception has profound effects on human consciousness, influencing cognition, affect regulation and behavior. Typically speaking, we perceive life as a continuous timeline — yet, the perception of time allows us to determine how we perceive the past, present, and future, thus affecting our sense of self and what is real. However, when someone consumes a psychedelic compound like DMT, LSD, or even Salvia Divinorum, their perception of time can change to the point where they claim to believe that they’ve experienced hours, and sometimes even decades of their life, or even eternity when tripping, a phenomenon known as time dilation. Such distortions in the perception of time offer us insight into how the brain processes time. They disrupt the assumptions of traditional models of consciousness. This reminds us how something as essential as time can be. What happens to our brain when we lose perception of time is where things become interesting. To understand more about how the perception of time changes between psychedelic experiences, we will go through three typical scenarios reported by the psychedelic community.

Additionally, the augmented attention to sensory stimuli during a trip can also interfere with time perception as the brain attempts to process information at a higher rate. But on the other side of the coin, some people describe hours passing like minutes. This could be linked to what the psychonaut community calls “ego dissolution,” which can loosen someone’s perception of time. For this reason, it’s believed that time compression could be caused by the alteration in serotonin levels and consequent effect on the cortical activity via the 5-HT2A receptor. The third-mentioned hypothesis is the effect of timelessness itself, a complete dissociation of the passage of time, once this happens, users typically describe profound or mystical experiences, and it’s believed that this might be a products of changes in the default mode network (DMN) of the brain, as the default mode network is associated with self-referential thinking and perception of continuous time, its suppression during these altered states could result in the dissolution of time as a boundary, past, present and future are perceived as irrelevant or a unified moment. As every human body reacts differently to these compounds and the sense of temporal distortions, these experiences can vary depending on the type/class of compound, dosage, and setting. Additionally, distinctions between compounds bring up the possibility that different pharmacological interactions could be the key to understanding such modifications to time perception, at least amongst psychedelics, demonstrating that the neural substrates that mediate these experiences are multifaceted. Such alteration in the perception of time while in psychedelic states could provide a novel perspective to study the brain mechanisms in temporal processing, and pave new perspectives for the study of the role of consciousness and its influence in what we consider reality. But first, we must address the big elephant in the room: How do psychedelics alter our perception of time? Our ability to understand time perception is influenced by the activity of distributed brain regions, neurotransmitters, and neural synchrony. Basal ganglia: Implicated in interval timing on the scale of hundreds of milliseconds, functioning as a putative internal clock, generating temporal predictions based on sensory evidence.   Prefrontal Cortex: Encodes longer time spans and combines information for planning and making decisions. Crucial for controlling dynamic time-based tasks.   Cerebellum: Refines motor coordination and precise timing by integrating sensory input and motor output for precise timing events. By integrating interception of internal body states with cognitive perception, the insula has a modulating role in how emotions and somatic sensations shape our perception of time. Neurobiological mechanisms of psychedelic-induced time perception alterations.   These processes are further regulated by major neurotransmitter systems. Dopamine: Acts primarily through the basal ganglia and modulates short-interval timing. Dysregulation is linked to timing deficits.   Serotonin (particularly via the 5HT2A receptor activation): Influences longer time scales. Is the primary mediator of psychedelic-induced time distortions Interfacing emotional and sensory processing with subjective time experience.   Glutamate (largely through the NMDA receptor-mediated neurotransmission): Supports the neural encoding and maintenance of precise temporal representations needed for various cognitive tasks.

Pitch us your idea via email In order to have a precise time perception, there must be a temporal coordination of neural activity between distant brain areas (generally mediated by neural synchrony), almost like a neurobiological orchestra within our body; these rhythms allow the synchronicity of sensory, motor, and cognitive activities. Once we disrupt the synchronicity, it may result in a distorted perception of time. This is exactly what happens when we take a psychedelic compound: it strongly affects the rhythm of this orchestra, resulting in the disrupted time perception due to the modulation of the brain’s sensory, calm, and self-reference system. One key factor for the mediating role of these changes is the Default Mode Network (DMN), comprised of: Medial prefrontal cortex, Posterior cingulate Angular gyrus Related to self-referential thinking and the brain’s internal model of time,
