In this episode of BrainWaves, Eva sits down with Dr. Caterina Gratton, Associate Professor of Psychology at UIUC and PI of Gratton Lab, to unpack how our brains create, store, and protect memories. From the mysteries of neuroplasticity to the science of cognitive resilience, this episode dives into how brain networks evolve with age and what cutting-edge research reveals about keeping our minds sharp.
🧠Key Terms
Neural Networks: Systems of connected brain regions that communicate and coordinate activity. Dr. Gratton studies how these large-scale networks shape memory and cognition.
Cognitive Control: The brain’s ability to direct thoughts and actions toward goals — focusing attention, ignoring distractions, and switching tasks.
Neuroplasticity: The brain’s capacity to change and reorganize through learning or after injury.
Brain Network Desegregation: With age, once-separate brain networks start interacting more, which can help integrate information but may reduce efficiency.
Transcranial Magnetic Stimulation (TMS): A non-invasive technique using magnetic pulses to modulate brain activity; used in research and depression treatment.
Deep Brain Stimulation (DBS): A surgical method using implanted electrodes to treat neurological disorders like Parkinson’s.
Precision Brain Mapping: Collecting detailed, individual brain data to tailor treatments and better understand personal differences in brain networks.
