In this episode, my guest is Dr. Mark D'Esposito, M.D., a neurologist and professor of neuroscience and psychology at the University of California, Berkeley. We discuss the brain mechanisms underlying cognition and the forms of memory required for focus, productivity, planning and achieving goals, and learning. We discuss neurochemicals such as dopamine and acetylcholine and how they can be leveraged to improve cognitive functioning. We also discuss concussion, traumatic brain injury (TBI), Alzheimer's, and Parkinson's disease, and ways to restore or slow cognitive decline by using pharmacologic, lifestyle and behavioral protocols. This episode provides a modern understanding of cognition and memory and actionable tools to optimize brain health and function. *Thank you to our sponsors* AG1: Maui Nui: Joovv: Eight Sleep: LMNT: Momentous: *Dr. Mark D'Esposito* Academic profile: Lab website: BrainHealth project: Publications: X: *Journal Articles* Cognitive and attentional mechanisms in delay of gratification: Inverted-U–Shaped Dopamine Actions on Human Working Memory and Cognitive Control: Cognitive Deficit Caused by Regional Depletion of Dopamine in Prefrontal Cortex of Rhesus Monkey: Clinical experience with the α2A-adrenoceptor agonist, guanfacine, and N-acetylcysteine for the treatment of cognitive deficits in “Long-COVID19”: Estrogen Shapes Dopamine-Dependent Cognitive Processes: Implications for Women's Health: Ongoing dynamics in large-scale functional connectivity predict perception: *Other Resources* BrainHQ: The BrainHealth Project: Neuroscouting: *Huberman Lab Episodes Mentioned* Nicotine's Effects on the Brain & Body & How to Quit Smoking or Vaping: Tools to Enhance Working Memory & Attention: Dr. Matthew Walker: The Science & Practice of Perfecting Your Sleep: How Psilocybin Can Rewire Our Brain, Its Therapeutic Benefits & Its Risks: *People Mentioned* Brian Levine: Professor Dept. of Psychology, University of Toronto: Matthew Walker: Professor of Neuroscience & Psychology, UC Berkeley: Michael Merzenich: Professor Emeritus - Neuroscience, USCF: David Hubel and Torsten Wiesel: Nobel Prize (1981): Emily Jacobs: Associate Professor of Psychology, UC Santa Barbara: Art Kramer: Professor Emeritus, University of Illinois Urbana-Champaign: Eddie Chang: Professor of Neurological Surgery, UCSF: Karl Deisseroth: Professor and Psychiatrist, Stanford: Sepideh Sadaghiani: Associate Professor of Psychology, University of Illinois Urbana-Champaign: *Timestamps* 00:00:00 Dr. Mark D’Esposito 00:02:08 Sponsors: Maui Nui, Joovv & Eight Sleep 00:06:23 Brain & Frontal Lobes, Prefrontal Cortex, Executive Function 00:10:31 Frontal Lobe Development, Children 00:14:12 Rules, Context & Impulse Control; Learning & Goals 00:21:45 Focus, Improving Executive Function 00:26:04 Connections & Top-Down Signals 00:29:02 Sponsor: AG1 00:30:29 Frontal Lobe Injury; Emotional Regulation 00:37:26 Smartphones, Social Media 00:44:37 Working Memory, Dopamine 00:52:59 Sponsor: LMNT 00:54:22 Dopamine Levels & Working Memory, Cognitive Tasks, Genetics 01:00:03 Bromocriptine & Working Memory, Dopamine 01:06:21 Guanfacine, Neurotransmitter Levels, Pupil Dilation & Biomarker Tests 01:12:46 Bromocriptine, Olympics; Pharmacology & Cognitive Function, Adderall 01:19:27 Concussion, Traumatic Brain Injury (TBI) 01:25:22 Sleep, TBI, Concussion & Executive Function; BrainHQ 01:31:57 Aging & Frontal Executive System; Brain Health 01:39:26 Tools: Brain Health & Boosting Executive Function, Books 01:47:26 Alzheimer’s Disease, Genetics, Pharmacology 01:51:48 Parkinson’s Disease, L-Dopa; Coping with Alzheimer’s; Nicotine 01:58:37 Estrogen & Dopamine, Cognition; Tool: Physical Exercise 02:04:43 Tool: Mindfulness Meditation & Executive Function 02:10:31 Brain Networks; Modularity 02:17:08 Modularity, Brain Indices 02:22:53 Psilocybin; Transcranial Magnetic Stimulation 02:30:16 Zero-Cost Support, Spotify & Apple Reviews, YouTube Feedback, Sponsors, Momentous, Social Media, Neural Network Newsletter #HubermanLab Disclaimer:
