In this episode, we explore the ins and outs of exercise and brain-derived neurotrophic factor (BDNF), which is integral to memory, nerve growth, memory, learning, and memory; did we say that already? Our special guest this week is exercise physiology PhD candidate Greg Spicer whose dissertation focuses on exercise modalities and acute cardiovascular and neurological responses, including BDNF.
