What's fascinating about exercise is how it affects our neurotransmitters. When we engage in physical activity, we see increases in dopamine, norepinephrine, and BDNF - brain-derived neurotrophic factor - which essentially helps our neurons grow and make new connections.

Hello everyone, I'm Dr. Andrew Huberman, professor of neurobiology and ophthalmology at Stanford School of Medicine. Today, I want to talk to you about something we all chase—but often misunderstand: Most people think motivation is a feeling. Something you wait for. But motivation is not something that simply arrives. It is something that is created. And more importantly—it is something that is sustained through very specific neurological processes that you can control.

Let's talk about how temperature affects our biology. What's fascinating is that our body's response to cold exposure triggers several important chemical cascades. Most people don't realize that these responses actually influence our alertness and cognitive function throughout the day.

Today on the Huberman Lab Podcast, we're exploring the science of stress response and how it affects our nervous system. As a neuroscientist, I'll explain the key mechanisms that regulate our fight-or-flight response and provide science-based tools to manage stress effectively.

When we look at how serotonin functions in the brain, it's important to understand that it's not just about happiness. Actually, serotonin plays a crucial role in your sleep-wake cycles, your appetite regulation, and even how you process emotional information.

When we look at the neural mechanisms of focus, it's critical to understand the role of dopamine. What I recommend is engaging in brief, intense exercise first thing in the morning, which can increase dopamine release and optimize your attention for several hours.

When we examine the effects of bright light exposure in the morning, it turns out that this triggers a cascade of neural events in the suprachiasmatic nucleus, which then signals to your entire body that it's time to be alert and active.

Today we're examining the neuroscience of decision-making, specifically how our brain processes choices and rewards. Understanding these neural pathways helps us grasp why we feel certain ways about our decisions and how our emotional responses shape our behavior patterns.
