Jo Marchant, science journalist and author of In Search of Now, unpacks how the brain constructs the present. She explores how moments blend multiple timescales, how memory is recreated in the present, and how perception depends on bodily action. She also links neuroscience to physics to argue our choices help build reality.

Episode notes
Pause To Direct Your Present Moment
- Pause and shift attention to what matters when feeling rushed to regain control of your constructed now.
- Marchant explicitly recommends taking a breath and consciously focusing to change your unfolding present.
When Time Threads Unravel Identity
- In schizophrenia and psychedelic ego death, the brain's integration of timescales can break, fragmenting identity from moment to moment.
- Marchant links these clinical and drug-induced examples to show how time-weaving sustains self.
Memories Are Rewritten In The Present
- Memory is not a replay but a creative act performed in the present, shaped by current beliefs and imagination.
- Marchant describes false-memory studies and neuroscience showing memory networks overlap with imagination networks.
