Ayahuasca-induced personal death subjective experiences
Researchers analysed studies on self-reported experiences related to the sensation of death during ayahuasca ceremonies.
Could we have psi abilities if our brains didn't inhibit them?
Research tests a novel neurobiological model and concludes that the frontal lobes of the brain act as a filter to inhibit humans' innate psi abilities.
The impact of after-death communication in bereavement
A study with 70 participants who experienced after-death communication with deceased partners reveals that the majority found it comforting and helpful in their bereavement.
The perception of visual motion
Everyday interactions with the environment require a correct estimation of both self- and object- motion velocities. Perception of object-motion speed is essential to approach or avoid them properly. In many circumstances, object-motion perception is complicated by concomitant self-motion. One of the main challenges for the visual system is to determine the source of the movement that generates the flow pattern: self-motion, object-motion, or their combination. Thus, the research team led by Valentina Sulpizio aimed to establish (1) the sensitivity of several motion-related cortical regions (egomotion regions) to different visually induced motion conditions, including both self- and object-displacements and a combination of them; and (2) whether the activity of these regions was affected by the velocity of both self- and object-motion, thus providing new insight into their role in discriminating between different self- and object-motion velocities. A differentiated profile emerged among the egomotion regions (cingulate sulcus visual area, posterior cingulate sulcus area, posterior insular cortex [PIC], V6+, V3A, IPSmot/VIP, and MT+) during a visual motion stimulation including self- and object-displacements and a combination of them. All the egomotion regions (except area PIC) responded to all the possible combinations of self- and object-motion and were further modulated by the self-motion velocity. Interestingly, only MT+, V6+, and V3A were further modulated by object-motion velocities, hence reflecting their possible role in discriminating between distinct velocities of self- and object-motion. These findings are detailed in the paper Neural sensitivity to translational self- and object-motion velocities published in the journal Human Brain Mapping, in the scope the research project 24/20 - World-relative object motion: How the brain detects object motion while we are moving, supported by the BIAL Foundation.
