Pleasure & Pain

Category: Brain

Pleasure is vital for our survival - without it we wouldn't eat or have sex, and would soon die out as a species. But how does pleasure work and what gives us the most pleasure in life?

Memory Hackers

Memory is the glue that binds our mental lives. Without it, we’d be prisoners of the present, unable to use the lessons of the past to change our future. From our first kiss to where we put our keys, memory represents who we are and how we learn and navigate the world. But how does it work? Neuroscientists using cutting-edge techniques are exploring the precise molecular mechanisms of memory. By studying a range of individuals ranging—from an 11-year-old whiz-kid who remembers every detail of his life to a woman who had memories implanted—scientists have uncovered a provocative idea. For much of human history, memory has been seen as a tape recorder that faithfully registers information and replays intact. But now, researchers are discovering that memory is far more malleable, always being written and rewritten, not just by us but by others. We are discovering the precise mechanisms that can explain and even control our memories. The question is—are we ready?

What do brains do?

Brains and nervous systems do a lot of things, but overall their purpose seems to be to allow cells to communicate and behave together. But because gene's generally code for things that help reproduction, you can start to see harsh patterns in behavior.

Engineering the Brain Deploying a New Neural Toolkit

A new generation of technology is revolutionizing neuroscience, allowing a closer study of the brain than had ever seemed possible. The techniques are hybrids of optics, genetics, and synthetic biology with the ability to manipulate brain activity, often in real time. Through direct stimulation of neural connections, some of these techniques hold the promise for the treatment of diseases like depression or schizophrenia.

The Brain that Changes Itself

Join us as we explore the revolutionary science of "neuroplasticity" - a concept that expands not just our knowledge of how our brains work, but how we use them. For centuries the human brain has been thought of as incapable of fundamental change. People suffering from neurological defects, brain damage or strokes were usually written-off as hopeless cases. But recent and continuing research into the human brain is radically changing how we look at the potential for neurological recovery. The human brain, as we are now quickly learning, has a remarkable ability to change itself - in fact, even to rewire itself. The Brain that Changes Itself, based on the best-selling book by Toronto psychiatrist and researcher Dr. Norman Doidge, presents a strong case for reconsidering how we view the human mind.

The Stilwell Brain

There are 100 billion individual neurons in the human brain. Working together, they allow us to make sense of, and move through, the world around us. Scientists have built replicas of the human brain with computers, but no one has ever successfully made a brain out of humans. On this episode, I’ll travel back to my hometown of Stilwell, Kansas, and turn it into a working brain!

The Social Brain

The traditional narrative is that humans are selfish. If pushed, the story goes, we look after ourselves first and others later. In this episode, we see how modern neuroscience has blown that myth apart.
