In this episode, my guest is Dr. Charan Ranganath, Ph.D., professor of psychology and neuroscience at the University of California, Davis, and a world expert on the neuroscience of memory. We discuss how memory works, what causes diseases of dementia like ...

Highlights

This episode delves into the neuroscience of memory, exploring how the brain forms, retains, and reinterprets experiences across the lifespan. Host and guest examine the biological underpinnings of cognitive resilience, the impact of attention and emotion on recall, and science-backed strategies to support long-term brain health.

06:48

Memory helps create an internal model of the world using past information selectively.

16:20

Neuroplasticity does not shut down with age; it's the willingness to learn that often declines.

21:00

Being curious about a question boosts memory for unrelated faces.

30:09

An animal deprived of dopamine will take rewards but won't work for them

37:33

Social media algorithms prioritize dwell-time; we need an algorithm for curiosity.

40:41

The hippocampus links experiences to context, enabling episodic memory like recalling events at specific times and places.

48:57

Older people are as good as younger ones at remembering distractions in a memory task

56:13

Depression disrupts dopamine activity and reduces curiosity, harming memory.

1:00:40

Those with 4–6 healthy lifestyle factors performed almost twice as high on memory tests

1:22:44

Relating actions to values is a game-changer for maintaining purpose.

1:26:18

Intention directs attention based on internal goals, distinguishing it from passive distraction.

1:35:21

Using a separate phone only for social media with a timer reduces daily usage and enhances focus.

1:44:45

The waiting process of a Polaroid makes it more memorable than digital photos

1:48:41

Strong goal focus can regulate dopamine and norepinephrine release via prefrontal cortex control

1:58:14

Lifestyle factors can reduce Alzheimer's risk by at least 40%

2:02:46

Stimulating the anterior temporal lobes can induce déjà vu and vivid memories.

2:17:48

Psilocybin and psychedelics show promise for inducing massive plasticity

2:19:07

Ibogaine users report high-definition recall of life events with full agency when eyes are closed

2:28:01

Rumination worsens negative memories, while nostalgia's impact depends on perspective

2:30:30

Pavlov’s Dogz Band performs punk rock covers at neuroscience events
