A Neurosurgeon’s Fascinating Ride Inside Your Brain | Dr Chandan ys | TEDxElliots Beach
TEDx Talks· 2025-10-29 15:58
Let me begin by asking you a simple question. Where do we live. Do we live in a city. Do we live in a town. Do we live in a house with walls and windows.If you really think about it, we live inside our brain. And everything we experience from the people we love, the choices we make and even the way we look at ourselves, it's quietly filtered a small organ sitting inside your skull. I'm Dr.. Chandan. I'm a neurosurgeon and my job gives me a rare privilege of not only seeing this organ but even holding it. An ...
Healing isn’t always linear | Dr. LaTanya Runnells | TEDxDel Sur Women

Core Concept - The brain is likened to a computer with components such as the prefrontal cortex (operating system), limbic system (emotional headquarters), amygdala (alarm/firewall), and neuroplasticity (software update) [2][3][4] - A mental breakdown is not a sign of weakness but a reset mechanism indicating the brain's current wiring is insufficient [16] - Healing from a breakdown involves a process that may initially worsen symptoms before improvement [10][11] Brain Function During Stress - Constant stress triggers the amygdala, acting as a smoke detector, to sound an alarm [5][6] - During a breakdown, the prefrontal cortex, responsible for logic, memory, and problem-solving, becomes overwhelmed, leading to a shutdown of these functions [7][8] - Raw emotions from the amygdala, such as anger, aggression, and sadness, surge during a breakdown, causing a feeling of loss of control [8] Neuroplasticity and Recovery - Neuroplasticity is the brain's ability to rewire itself, enabling recovery and growth after a breakdown [4][14] - New choices, prayers, and exercises can create new neural pathways, calming the amygdala, strengthening the prefrontal cortex, and restoring balance [15] - The brain that experiences a breakdown is the same brain capable of rebuilding and functioning effectively [14][15]
The potential of the adolescent brain | Anagha Hamsala | TEDxMcfarren Boulevard Youth

Neuroscience of Adolescence - Adolescence is a unique window of opportunity due to increased neuroplasticity, the brain's ability to reorganize itself and form new neural connections [2][5] - During teenage years, brains are most adaptable, primed for learning and growth, but also highly susceptible to negative influences [5] - Environments directly impact brain growth, highlighting the importance of harnessing neuroplasticity to focus, adapt, and thrive [6] - Neuroscience reveals adolescence is about brains actively shaping who individuals become, with neuroplasticity at its peak [7] Enhancing Focus and Habits - Exercise and mindfulness produce brain-derived neurotrophic factor (BDNF), a protein that supports neurogenesis, the production of new neurons [8] - Neuroplasticity thrives on challenge, novelty, and even failure, as brains form new connections in uncomfortable situations [8][9] - Focus is about saying yes to the right things, activating the prefrontal cortex, the brain's CEO responsible for decision making and planning [10][11] - Small achievements release dopamine, the brain's feel-good neurotransmitter, suggesting breaking down goals into smaller, manageable tasks [12][13] - Multitasking is ineffective; the brain prefers doing one thing well, and switching between tasks leads to lost time and productivity [13][14] - Habit stacking involves pairing a new habit with an existing one to prime the brain for focus and growth [15] Influence of Environment and Social Connections - Individuals mirror the behaviors of those around them due to mirror neurons, emphasizing the importance of surrounding oneself with optimistic and supportive people [17][18] - Being intentional with what one consumes and being an inspiration for others can create a ripple effect of positive influence [19][20]
Neurofitness: Exercising the Brain | Juan Pablo Barea | TEDxYouth@AICS

Heat. Heat. [Music] [Music] [Applause] What if I told you there's something that you can take today that would optimize your cognitive functions like memory, focus, and also give you a mood boost that would last for around 3 hours.But uh if you did that repetitively in the long term, it would also have benefits against Alzheimer, dementia, and even depression. Would you take it. Yes.Right. So, I'm here to talk to you about the positive effects that physical exercise have in your brain. I call it neuro fitne ...
