In 1,884, while attempting to define the limits of human perception, Charles Pierce and Joseph Jastrow discovered something else: the limits of our insight into ourselves.
Participants in their experiments systematically under-rated their ability to correctly judge their own sensations, which Pierce and Jastrow offered as an explanation of “the insight of females as well as certain ‘telepathic’ phenomena”. These particular implications have thankfully been left behind (along with the conceptual relationship between telepathy and female insight). But by the late 1970s this approach of asking participants to rate their own performance had emerged as its own field of research: the study of “metacognition”.
Broadly, this ability to self-reflect and think about our own thoughts allows us to feel more or less confident in our decisions: we can act decisively when we’re confident we are correct, or be more cautious after we feel we’ve made an error.

In this episode, Dr. Huberman is joined by Dr. David Berson, Professor and Chairman of Neuroscience at Brown University. Dr. Berson discovered the neurons in your eye that set your biological rhythms for sleep, wakefulness, mood and appetite. He is also a world-renowned teacher of basic and advanced neuroscience, having taught thousands of university lectures on this topic. Many of his students have become world-leading neuroscientists and teachers themselves.
Here Dr. Berson takes us on a structured journey into and around the nervous system, explaining: how we perceive the world and our internal landscape, how we balance, see, and remember. Also, how we learn and perform reflexive and deliberate actions, how we visualize and imagine in our mind, and how the various circuits of the brain coordinate all these incredible feats.
A common solution is emerging in two different fields: developmental biology and neuroscience.

MIT is an acronym for the Massachusetts Institute of Technology. It is a prestigious private research university in Cambridge, Massachusetts that was founded in 1861. It is organized into five Schools: architecture and planning; engineering; humanities, arts, and social sciences; management; and science. MIT’s impact includes many scientific breakthroughs and technological advances.
In this video, Dr. Lila Landowski shares footage of two neurons connecting in a dish. Here’s what Lila had to say about the footage:
You’re watching two neurons that I saw under the microscope sensing one another and connecting.
There are 86 billion neurons in the brain — how do they know how to connect to other neurons or body parts when our bodies are developing?

Scientists and philosophers have pondered the nature of consciousness for centuries. But now, researchers from Japan have uncovered new information that challenges previous theories about the relationship between two elements of consciousness.
In a study published this month in iScience, researchers from the University of Tsukuba have revealed that when the perception of bodily self-consciousness is distorted, the recovery of body ownership can be predicted by different kinds of memories.

A molecule that shows promise in preventing Parkinson’s disease has been refined by scientists at the University of Bath in the UK, and has the potential to be developed into a drug to treat the deadly neurodegenerative disease.
Professor Jody Mason, who led the research from the Department of Biology and Biochemistry at Bath, said: “A lot of work still needs to happen, but this molecule has the potential to be a pre-cursor to a drug. Today there are only medicines to treat the symptoms of Parkinson’s—we hope to develop a drug that can return people to good health even before symptoms develop.”
