In this Huberman Lab Essentials episode, I explore how your sense of smell (olfaction), taste, and chemical sensing influence memory, alertness, focus, and even communication between people. I explain how these senses help us detect chemicals in the environment and respond to a variety of environmental cues. I discuss the connection between the olfactory system and cognitive performance, and I provide practical tools to enhance learning, sensory function, and brain health. Additionally, I examine how chemical signals exchanged between people subtly influence emotions, biology, and social bonds. Huberman Lab Essentials episodes are approximately 30 minutes long and focus on key science and protocol takeaways from past Huberman Lab episodes. Essentials are released every Thursday, while full-length episodes continue to air every Monday. Read the episode show notes at hubermanlab.com. Huberman Lab Essentials are short episodes focused on essential science and protocol takeaways from past full-length Huberman Lab episodes.

Highlights

This episode delves into the profound yet often overlooked influence of our chemical senses—smell and taste—on brain function, behavior, and social interaction. Far beyond mere perception of flavors and fragrances, these senses are deeply wired into our nervous system, shaping memory, alertness, and even subconscious communication between individuals.

Women's emotional tears reduce men's testosterone and sexual arousal
07:18
Olfaction is the most ancient sense and directly linked to memory

Exposure to a post-pubertal male's scent can trigger earlier puberty in pre-pubertal females (Vandenbergh effect)
12:44
Inhaling through the nose boosts brain alertness and learning capacity
16:15
Smelling an orange can enhance both smell and taste perception
18:11
Olfactory neurons are among the few brain cells that regenerate throughout life.
20:17
Recovery of smell can indicate concussion recovery
22:29
Peppermint and smelling salts trigger alertness via olfactory neurons
24:34
Taste receptors are intermixed on the tongue; the 'taste map' is a myth
32:41
Tears contain chemicals that suppress male sexual desire.
